Description

The present invention relates to technology for transferring images between devices.

With the recent increase in data transfer speeds over networks, imaging devices such as cameras are now able to transfer captured images to external devices such as server computers over a network. With such image transfer functions, the user of the imaging device can specify the images to be transferred as the transfer target. The images specified as the transfer target are then transferred sequentially from the imaging device to the external device. It is desirable for the operation of specifying the images to be transferred to be as simple as possible and involve fewer steps for the user, such as pressing multiple buttons. Patent Document 1 discloses a technology for controlling whether images captured by a camera are transferred automatically or according to user instructions.

By the way, when images designated for transfer are transferred in sequence as described above, it would be useful to have a way to allow images that are later in the transfer order or images that are not designated for transfer to be prioritized by cutting in on them earlier in the transfer order.

The present invention was made in consideration of the above problems, and its purpose is to realize a technology that allows users to quickly select images they want to transfer with simple operations and transfer them preferentially.

In order to solve the above problems and achieve the object, a communication device of the present invention is a communication device having a communication means capable of communicating with an external device, an imaging means, a display means for displaying an image, and a control means for controlling a function of setting the image displayed by the display means as a transfer target image to be transferred to the external device, and when a first user operation is received in a state in which a first image that is not set as the transfer target image is being displayed by the display means and a second image that is not set as the transfer target image is not being displayed, the control means sets the first image as the transfer target image, and when the first user operation is received in a state in which the first image already set as the transfer target image is not being displayed by the display means and a second image that is not set as the transfer target image is being displayed, the control means sets the second image as the transfer target image and managing the first image as an image to be transferred after the first image already set as the image to be transferred, and when a second user operation different from the first user operation is performed while the first image set as the image to be transferred is being displayed and the second image set as the image to be transferred is not being displayed, the control means sets the first image as an image to be transferred preferentially over the second image set as the image to be transferred, and when the second user operation is performed while the second image set as the image to be transferred is being displayed and the first image set as the image to be transferred preferentially is not being displayed, the control means sets the second image as the image to be transferred preferentially, and manages the second image as an image to be transferred before the first image set as the image to be transferred

According to the present invention, it is possible to quickly select the images you want to transfer with simple operations and transfer them preferentially.

The following describes in detail the form for carrying out the present invention. Note that the embodiment described below is one example for realizing the present invention, and should be appropriately modified or changed depending on the configuration of the device to which the present invention is applied and various conditions, and the present invention is not limited to the following embodiment. In addition, a configuration may be made by appropriately combining parts of each of the embodiments described below.

In this embodiment, a system is described in which an imaging device such as a digital camera or a communication device with a camera function transfers content such as images to an external device such as a server computer (PC) via a communication network. Note that the imaging device of this embodiment is not limited to a digital camera, and may be, for example, a tablet device, a media player, a surveillance camera, medical equipment, etc. Also, the communication device with a camera function may be, for example, a smartphone, which is a type of mobile phone, a digital camera with a communication function, a tablet device, etc. Also, the external device of this embodiment is not limited to a server computer, and may be, for example, a smartphone, which is a type of mobile phone, a digital camera with a communication function, a tablet device, a personal computer (PC), etc.

<Device configuration> With reference to Figure 1, the configuration and functions of the imaging device 100 of this embodiment will be outlined.

In FIG. 1, (a) is a functional block diagram of the imaging device 100 of this embodiment, and (b) is a rear view.

In FIG. 1(a), the control unit 101 is a central processing unit (CPU) that controls the entire imaging device 100, and realizes each process of the flowchart described below by executing a program stored in a non-volatile memory 106 described below. Note that instead of the control unit 101 controlling the entire device, the entire device may be controlled by multiple hardware devices sharing the processing.

The optical system 102 includes a group of lenses including a zoom lens and a focus lens, and a shutter with an aperture function. The imaging unit 103 is an image sensor composed of a CCD, CMOS, or the like that converts a subject image into an electrical signal. The A/D converter 104 converts the analog image signal output from the imaging unit 103 into a digital signal.

The image processing unit 105 performs resizing processes such as pixel interpolation and reduction and color conversion processes on image data such as video and still images captured by the imaging unit 103. The image processing unit 105 also compresses and encodes the still image data that has been subjected to the above processing using JPEG or the like, and encodes the video data using a video compression method such as MPEG2 or H.264 to generate an image file, which is then recorded on the recording medium 111. The image processing unit 105 also performs a predetermined calculation process using the captured image data, and based on the obtained calculation result, the control unit 101 controls the focus lens, aperture, and shutter of the optical system 102 to perform AF (autofocus) processing and AE (autoexposure) processing. Furthermore, the image processing unit 105 also generates a live view image for checking the composition and focus when shooting.

The non-volatile memory 106 is an electrically erasable and recordable memory, and may be, for example, an EEPROM. Constants and programs for the operation of the control unit 101 are recorded in the non-volatile memory 106. The programs referred to here are programs for executing various flowcharts described later in this embodiment.

The working memory 107 is used as a working area for expanding constants and variables for the operation of the control unit 101, programs read from the non-volatile memory 106, and the like. The working memory 107 is also used as a buffer memory for temporarily storing image data captured by the imaging unit 103, and as an image display memory for the display unit 109.

The operation unit 108 is an operation means such as various switches, buttons, a touch panel, etc. that accepts user operations, and includes, for example, operation members 112 to 118 shown in FIG. 1(b). The configuration of each of the operation members 112 to 118 will be described later. The control unit 101 controls communication with external devices, image capture, display, playback, etc., based on instructions from the operation unit 108 in response to user operations. The control unit 101 also executes transfer processing of played back images and captured images, which will be described later. The control unit 101 also controls a transfer management list used in the transfer processing of this embodiment.

The display unit 109 displays a live view image during preparation for shooting, displays captured images, and displays text for interactive operations. The display unit 109 is, for example, a display device such as a liquid crystal display or an organic EL display. The display unit 109 may be integrated with the imaging device 100, or may be an external device connected to the imaging device 100.

The recording medium 111 records image files encoded by the image processing unit 105, and reads out image files already recorded by the control unit 101. The recording medium 111 may be a memory card or a hard disk drive that is attached to the imaging device 100, or may be a flash memory or a hard disk drive built into the imaging device 100.

The communication unit 110 is an interface for connecting to an external device 200 such as a smartphone or a PC, which will be described later in FIG. 2, so as to be able to communicate with the external device 200. The imaging device 100 of this embodiment can exchange data with the external device 200 via the communication unit 110. For example, the control unit 101 can transmit image data generated by the imaging unit 103 to the external device 200 via the communication unit 110. In this embodiment, the communication unit 110 includes an interface for communicating with the external device via a so-called wireless LAN or WiMAX in accordance with the IEEE802.11 standard. The control unit 101 realizes wireless communication with the external device 200 by controlling the communication unit 110. Note that the communication method is not limited to wireless LAN, and for example, Bluetooth (registered trademark) can be used. Wired communication such as Ethernet (registered trademark) or USB (Universal Serial Bus) may also be used.

Here, the configuration of the operation unit 108 of the imaging device 100 of this embodiment will be described with reference to FIG. 1(b).

The operation unit 108 includes push button type operation members such as an OK button 112, a set button 113, a playback button 114, a multi-controller 115, a shooting button 116, a rating button 117, and a magnification button 118. In addition, these operation members 112 to 118 may be in the form of touch buttons provided on a touch panel that is integral with the display unit 109.

The OK button 112 is an operating member that sends an instruction to the control unit 101 to confirm an item or setting selected by the user on a menu screen or the like. The OK button 112 is used to have the user determine in advance whether or not final confirmation by the user is required for settings, such as images to be deleted or images to be transferred.

The set button 113 is an operating member that sends an instruction to the control unit 101 to confirm an item selected by the user on a menu screen or the like. The set button 113 is a button used for user selection, similar to the OK button 112, but is used for more general-purpose selection operations, such as when the user selects an item, image, or the like on a menu screen or the like.

The play button 114 is an operating member that sends an instruction to play an image (an instruction to switch to a play mode) to the control unit 101. In response to pressing the play button 114, the control unit 101 can perform a playback process in which the image data recorded on the recording medium 111 is read, temporarily stored in the working memory 107, and displayed on the display unit 109.

The multi-controller 115 includes up, down, left and right cross keys, and is an operation member that sends instructions to the control unit 101 for the user to select an item or image on a menu screen or the like. The user can move the cursor to a desired position by pressing the up, down, left and right keys on the multi-controller 115, and select a desired item or image by pressing the set button 113.

The shooting button 116 is an operating member such as a shutter release button or a recording start button that the user operates to send a command to start shooting to the control unit 101. In response to pressing the shooting button 116, the control unit 101 starts a series of shooting processes, such as shooting an image, displaying a quick review of the image immediately after shooting, and writing the image to the recording medium 111, in accordance with a program stored in the non-volatile memory 106.

The rating button 117 is an operating member that sends an instruction to the control unit 101 to assign a rating to the image being played. In response to the rating button 117 being pressed while an image is being played, the control unit 101 assigns a rating to the image being played.

The enlarge button 118 is an operating member that sends an instruction to the control unit 101 to enlarge and display the image being played. In response to the enlarge button 118 being pressed while the image is being played, the control unit 101 enlarges the image being played.

Next, the system configuration of this embodiment will be described with reference to Figure 2.

2, in the system of this embodiment, the imaging device 100 described above is connected to an external device 200 such as a smartphone or a server computer (PC) as an image transfer destination via a network 201 that performs wireless communication or wired communication, and transfers the captured image. Although not shown, the external device 200 includes a control unit, a working memory, a non-volatile memory, an image processing unit, a communication unit, a display unit, an operation unit, a recording medium, and the like, similar to the imaging device 100. The network 201 is not particularly limited in terms of the communication method, as long as data transfer such as images between devices is possible. In this embodiment, as a use case for transferring images from the imaging device 100 to the external device 200, data communication based on FTP (File Transfer Protocol), which is one of the technologies used in the reporting business of television stations and newspapers, is assumed. In FTP, a function for automatically transferring images captured by the imaging device 100 and a function for starting image transfer by performing a predetermined operation during image playback can be used. Particularly at big events like the Olympics, it is expected that the photographer and the editor who processes the images will be different people, and in such situations, it is necessary to transfer the captured images to the editor as quickly as possible. In addition, as cameras' continuous shooting functions have become more powerful, a large number of images may be taken at once, and even in such situations, it is important to be able to select and transfer the images you want to transfer as quickly and easily as possible.

<Image transfer process> Next, the image transfer process performed by the imaging device 100 of this embodiment will be described with reference to FIG. 3.

3A illustrates an example of the display state of the display unit 109 during image playback. In response to pressing the playback button 114, the control unit 101 reads out image data recorded in the recording medium 111 and displays it on the display unit 109, while simultaneously displaying image-related information such as the file name 300 of the currently displayed image. In addition, in this embodiment, when it is determined that two specific buttons of the operation unit 108 are simultaneously pressed during image playback, the control unit 101 performs control to designate the currently played image as the image to be transferred. There are various configurations for which buttons the two buttons are assigned to, but it is generally desirable to assign them to a button that can be operated with the right hand and a button that can be operated with the left hand. This is because it is easy for the photographer to press the buttons simultaneously. For example, the two buttons are located on the left and right ends of the back of the camera body when the camera is held horizontally. In this embodiment, the image to be transferred is designated in response to the OK button 112 and the set button 113 being simultaneously pressed. Note that instead of the OK button 112, the rating button 117 and the enlargement button 118 may be used. Considering the operability of buttons that are pressed simultaneously, it is easier for the user to operate the buttons if they are located at the left and right ends of the back of the camera body when the camera is held horizontally.

Figure 3 (b) illustrates a state in which a first indicator 301 is displayed on the display unit 109 superimposed on the played-back image to indicate that the image is an image to be transferred. By displaying the first indicator 301 indicating that the played-back image is an image to be transferred in this manner, it is possible to clearly indicate to the user that the played-back image is an image to be transferred. Then, when an image to be transferred exists as described above and a connection with the external device to be transferred has been established by the communication unit 110, the control unit 101 controls the image to be transferred to be automatically transferred.

Figure 3(c) illustrates an example of a state in which an image to be transferred is being transferred. During image transfer, a second indicator 302 displayed with a dotted line is displayed on the display unit 109, indicating that a playback image is being transferred. In the illustrated example, the icon display form is changed between the first indicator 301 and the second indicator 302, but the icon display form may be the same and the color, etc. may be changed. The icon may also be made to blink. It is only necessary to clearly indicate to the user that the image has been selected as an image to be transferred and is waiting to be transferred, and has changed to a state in which it is being transferred. Figure 3(d) illustrates an example of a state after the transfer of the image to be transferred is completed. After the transfer of the image is completed, a third indicator 303 indicating that the transfer of the image is completed is displayed on the display unit 109. As with the second indicator 302 during image transfer shown in Figure 3(c), the third indicator 303 may be displayed by changing the icon display form, color, etc. Note that, as shown in FIG. 3B, when the OK button 112 and the set button 113 are pressed simultaneously while the image to be transferred is being played back, the control unit 101 cancels the designation of the image to be transferred. In this embodiment, pressing the OK button 112 and the set button 113 simultaneously functions as a toggle button that switches whether or not to designate the image to be transferred.

<Transfer management list> Next, we will explain the transfer management list for managing images to be transferred, with reference to Figure 4.

In FIG. 4, 400 is an image of an image file recorded on the recording medium 111. In the following, it is assumed that there are three file names, IMG_0001, IMG_0002, and IMG_0003, as image-related information of the image file 400 recorded on the recording medium 111, and the description will be given in accordance with each state of FIG. 3(a) to (d). In the state of FIG. 3(a), the image IMG_0001 is displayed on the display unit 109. In this state, when the control unit 101 detects the simultaneous pressing of the OK button 112 and the set button 113, it adds the file name (IMG_0001) to the transfer management list 401 as image-related information of the image to be transferred, and sets the transfer status indicating the transfer status of the image to "waiting for transfer". Then, as shown in FIG. 3(b), the first indicator 301 indicating that the image is the image to be transferred is displayed on the display unit 109. After that, when the image transfer status is switched to "in progress" as shown in FIG. 3C, the control unit 101 updates the transfer status of the image (IMG_0001) to "transferring" in the transfer management list 402. After that, when the image transfer is completed as shown in FIG. 3D, the control unit 101 updates the transfer status of the image (IMG_0001) to "transfer completed" in the transfer management list 403. Here, the control of the transfer management list when one image file is selected as the transfer target and the image is waiting to be transferred, being transferred, and transferred completed has been described, but it is also possible to add a plurality of images to be transferred to the transfer management list in advance as shown in 404. In this case, the images to be transferred are added sequentially as shown in the transfer management lift 404 in response to the simultaneous pressing of the OK button 112 and the set button 113 each time the playback image is switched. Then, the transfer status is updated each time each image to be transferred goes from waiting to be transferred to being transferred and transferred. The transfer management list is recorded in the non-volatile memory 106 or the recording medium 111, and is deployed to the working memory 107 when the control unit 101 uses it.

The transfer status of an image that is eligible for transfer can be "Waiting for transfer", "Transferring", or "Transfer completed", while the transfer status of an image that is eligible for priority transfer, which will be described later, can be "Waiting for priority transfer", "Transferring", or "Priority transfer in progress".

The above explanation describes the process of transferring playback images, but we will also explain the process of automatically transferring captured images. The imaging device 100 of this embodiment has a function that allows the user to select in advance whether or not to transfer captured images on a menu screen, etc., and automatically transfers captured images to the transfer destination when the device is set to automatically transfer captured images. Even in this case, automatic transfer at the time of capture can be achieved by adding captured images to the transfer management list in the order in which they were captured, just like playback images.

In the above-mentioned transfer process for played back images and captured images, the images to be transferred are transferred in the order in which they are registered in the transfer management list. In this case, it would be convenient if images that are later in the transfer order or images that are not specified as transfer targets could be moved to the top of the order and transferred preferentially. This type of function is particularly useful in use cases where it is necessary to transfer images as quickly as possible. Therefore, in this embodiment, a technology is realized that allows the images to be transferred to be quickly selected and transferred with a simple operation, without compromising the original operability while keeping the button layout of the existing camera.

Below, the priority forwarding process of this embodiment will be explained with reference to Figures 5 to 8.

<Priority transfer process during image playback>
Fig. 5 shows an example of a display when priority transfer is performed during image playback. The image to be transferred during playback in Fig. 5(a) and during playback in Fig. 5(b) is designated as described in Fig. 3(a) and Fig. 3(b). When the OK button 112 and the set button 113 are pressed simultaneously for a predetermined period of time or longer during playback of the image to be transferred 500 as in Fig. 5(b), the control unit 101 sets the image to be transferred 500 being played as the image to be transferred with priority transfer.

5(c) illustrates a state in which the image 500 to be transferred is set as a priority transfer target by simultaneously pressing and holding the OK button 112 and the set button 113 in the state of FIG. 5(b). In the state of FIG. 5(c), the image-related information (file name) of the image 500 to be transferred is moved to the top of the transfer management list, and the transfer status is updated to "waiting for priority transfer". Then, a fourth indicator 502 is displayed on the display unit 109 superimposed on the image 500 to be transferred, indicating that the image has been set as a priority transfer target. The fourth indicator 502 is displayed in a different form and color from the icon of the first indicator 501 so that it can be distinguished from the first indicator 501, and clearly indicates to the user that the image is a priority transfer target. In the illustrated example, the display form of the icon is changed between the first indicator 501 and the fourth indicator 502, but the display form of the icon may be the same and the color may be changed. It is sufficient to clearly indicate to the user that the image to be transferred has been changed to a priority transfer target.

Figure 5(d) illustrates an example of a state in which an image to be transferred with priority is being transferred. In the state of Figure 5(d), the transfer status of the image to be transferred 500 is updated to "priority transfer in progress", and the display unit 109 displays a fifth indicator 503 indicating that the image to be transferred with priority is being transferred. In the illustrated example, the fourth indicator 502 and the fifth indicator 503 change the icon display form, but the icon display form may be the same and the color, etc. may be changed. All that is required is to clearly indicate to the user that the image to be transferred with priority has changed from a selected state to a state in which it is being transferred.

5(e) illustrates the state after the transfer of the image to be transferred with priority is completed. In the state of FIG. 5(e), the transfer status of the image to be transferred 500 is updated to "priority transfer completed", and the display unit 109 displays a sixth indicator 504 indicating that the image transfer is completed. Note that it is not necessary to distinguish the image whose transfer has been completed from a normal icon, but a different display from the normal one may be used to clearly indicate to the user that the priority transfer has been completed. As with the fifth indicator 503 during image transfer shown in FIG. 5(d), the sixth indicator 504 may be displayed by changing the display form or color of the icon. Note that when the OK button 112 and the set button 113 are pressed simultaneously in the state where the image is set as the image to be transferred with priority as shown in FIG. 5(c), the control unit 101 cancels the priority transfer setting.

Here, a method of setting an image to be transferred with priority, which is different from that shown in FIG. 5, will be described. After an image to be transferred is designated as shown in FIG. 5B and a first indicator 501 is displayed on the display unit 109, the OK button 112 and the set button 113 are temporarily released, and the OK button 112 or the set button 113 is pressed within a predetermined time, thereby setting the image to be transferred with priority. In this setting method, the image to be transferred is designated by simultaneously pressing the OK button 112 and the set button 113, and then the image to be transferred with priority is set by pressing either button again within a predetermined time. Here, in addition to the time constraint of within a predetermined time, the condition may be, for example, the period until the display unit 109 turns off and transitions to a shooting standby state. It may also be the period until the next image is played.

<Priority transfer when taking pictures>
FIG. 6 shows a display example in the case where a priority transfer target is set when an image is captured. FIG. 6A shows an example of a capture standby state in which live view images are displayed one after another on the display unit 109. When the capture button 116 is pressed from this capture standby state, normal capture processing is started. Here, a use case is assumed in which an image to be captured is to be transferred with priority over existing images to be transferred. In this embodiment, taking such a use case into consideration, when the capture button 116 is pressed with the OK button 112 pressed in the capture standby state of FIG. 6A, one or more images captured thereafter can be set as priority transfer targets. In this case, as in this embodiment, it is more convenient to arrange the OK button 112 at a position where it can be operated with the left hand, compared to the capture button 116 operated with the right hand.

Figure 6(b) illustrates a quick review state for checking an image immediately after shooting. The captured image 600 in Figure 6(b) is an image that was captured with the OK button 112 pressed, and therefore has already been set as an image to be prioritized for transfer at the time of quick review. Therefore, a fourth indicator 601 indicating that the image is an image to be prioritized for transfer is displayed on the display unit 109, superimposed on the captured image 600. Figure 6(c) illustrates the state when the camera returns to the standby state for shooting after the quick review. Although Figure 6(c) shows the state in preparation for the next shooting, the control unit 101 cooperates with the communication unit 110 and transfer of the captured image continues in the background.

<Priority transfer during quick review>
Fig. 7 shows an example of a display when images to be preferentially transferred are set during quick review. Fig. 7(a) shows a shooting standby state in which live view images are successively displayed on the display unit 109, similar to Fig. 6(a).

Figure 7(b) shows an example of the quick review state immediately after the capture button 116 is pressed from the state shown in Figure 7(a) and the capture process is performed. Here, a use case is assumed in which, when a captured image is reviewed in quick review, the reviewed image is to be transferred with priority over existing images to be transferred. In this embodiment, taking such a use case into consideration, the OK button 112 and the set button 113 can be pressed simultaneously during the quick review of Figure 7(b) to set the captured image 700 being reviewed as the image to be transferred with priority.

Figure 7(c) shows a state in which the image being quick reviewed has been set as an image for priority transfer. A fourth indicator 701 is displayed on the display unit 109, indicating that the captured image 700 being quick reviewed has been set as an image for priority transfer. Figure 7(d), like Figure 6(c), shows an example of a state when the camera returns to standby for shooting after quick review, with image transfer continuing in the background.

Figure 8 shows a different display example of an image to be transferred by priority from Figure 7. Figure 8(a) shows a shooting standby state, similar to Figure 7(a). When the OK button 112 and the set button 113 are pressed simultaneously in the shooting standby state of Figure 8(a), a seventh indicator 802 indicating that the image has been designated as a transfer target image is displayed superimposed on the live view image 810, as shown in Figure 8(b). From the state of Figure 8(b), by pressing the shooting button 116 while holding down the OK button 112, one or more images taken thereafter can be set as images to be transferred by priority.

Figure 8(c) illustrates a quick review state for checking an image immediately after shooting, similar to Figure 7(b). The captured image 800 in Figure 8(c) has already been set as a priority transfer target at the time of quick review, and a fourth indicator 801 indicating that the image is a priority transfer target is displayed on the display unit 109. Figure 8(d) illustrates the state when the camera returns to a shooting standby state after quick review. Although Figure 8(d) shows a state in which the camera is in preparation for the next shooting, the control unit 101 is working with the communication unit 110 to continue transferring the captured image in the background. Note that the shooting process is completed in Figure 8(d), so the fourth indicator 801 is erased.

<Priority transfer process during image playback> Next, with reference to FIG. 9, the setting and transfer process of images to be transferred preferentially during image playback by the imaging device 100 of this embodiment will be described. Note that the process of FIG. 9 is realized by the control unit 101 of the imaging device 100 expanding a control program read from the non-volatile memory 106 into the working memory 107 and executing it. The same applies to FIGS. 10, 11, 12, 13, and 15 described below.

In S900, the control unit 101 acquires a transfer management list from the non-volatile memory 106 or the recording medium 111. In S901, the control unit 101 waits without proceeding to the next process until it determines that the play button 114 has been pressed, and if it determines that the play button 114 has been pressed, it proceeds to S902.

In S902, the control unit 101 checks the transfer status of the image to be played back in the transfer management list. As described in FIG. 4, the transfer status can be "waiting for transfer" or "waiting for priority transfer", "transferring" or "priority transfer in progress", or "transfer completed" or "priority transfer completed". In S903, the control unit 101 displays an indicator corresponding to the transfer status checked in S902 on the display unit 109, superimposed on the played back image.

In S904, the control unit 101 waits without proceeding to the next process until it determines that the OK button 112 and the set button 113 have been pressed simultaneously, and if it determines that the OK button 112 and the set button 113 have been pressed simultaneously, the process proceeds to S905. In S905, the control unit 101 checks whether the image being played is in the transfer management list obtained in S900, and if it is not in the transfer management list, the process proceeds to S906, and if it is, the process proceeds to S907.

In S906, the control unit 101 adds the image-related information (file name) of the reproduced image to the end of the transfer management list, and proceeds to S908. In S907, the control unit 101 checks whether the transfer status of the reproduced image registered in the transfer management list is "waiting for transfer" or "waiting for priority transfer", and if it is "waiting for transfer" or "waiting for priority transfer", proceeds to S920, and if not, proceeds to S908.

In S920, the control unit 101 deletes the image-related information of the played image from the transfer management list. In S921, the control unit 101 erases the display of the indicator indicating that the played image is to be transferred, resulting in the state shown in FIG. 5(a). In this way, the setting can be cancelled for a played image that has already been set as a transfer target or priority transfer target by simultaneously pressing the OK button 112 and the set button 113 during playback.

In S908, the control unit 101 updates the transfer management list to change the transfer status of the played image to "waiting for transfer". In S909, the control unit 101 displays an indicator indicating that the transfer status is "waiting for transfer" on the display unit 109, and the state becomes as shown in FIG. 5(b).

In S910, the control unit 101 determines whether the OK button 112 and the set button 113 are being pressed and held simultaneously, and if so, proceeds to S911 to make the currently displayed image a target for priority transfer, and if not, proceeds to S913. In S911, the control unit 101 moves the image-related information (file name) of the currently displayed image to the top of the transfer management list, and sets the transfer status to "waiting for priority transfer."

In S912, the control unit 101 displays an indicator on the display unit 109 indicating that the image is a target for priority transfer, resulting in a state as shown in FIG. 5(c). In S913, the control unit 101 checks the communication status with the external device 200 to which the image is to be transferred via the communication unit 110, and ends the process if a connection with the external device 200 has not been established, and proceeds to S914 if a connection has been established.

In S914, the control unit 101 waits without proceeding to the next process until the transfer of the image subject to priority transfer is started, and proceeds to S915 if it is determined that the transfer has started. In S915, the control unit 101 updates the transfer status in the transfer management list to "priority transfer in progress."

In S916, the control unit 101 displays an indicator on the display unit 109 indicating that priority transfer is in progress, resulting in a state as shown in FIG. 5(d). In S917, the control unit 101 waits without proceeding to the next process until priority transfer is complete, and proceeds to S918 when priority transfer is complete.

In S918, the control unit 101 updates the transfer status in the transfer management list to "Transfer Complete". In S919, the control unit 101 displays an indicator on the display unit 109 indicating that the transfer status is "Transfer Complete", resulting in a state as shown in FIG. 5(e). When the transfer of the images subject to priority transfer is complete, the transfer of images that are not subject to priority transfer and have a transfer status of "Waiting for transfer" is initiated.

The priority transfer process of FIG. 9 described above allows the image to be selected for priority transfer quickly with a simple operation that can be performed immediately after the operation to specify the image to be transferred during image playback, providing a means to accurately meet the need to transfer images as quickly as possible.

In FIG. 9, the condition for setting the image to be transferred by priority and for starting the transfer process is set when the OK button 112 and the set button 113 are pressed and held simultaneously in S910, but the button combination and operation method are not limited to those described above. For example, the condition may be when the set button 113 is double-clicked (pressed twice in succession) while the OK button 112 is pressed, or when the OK button 112 is double-clicked while the set button 113 is pressed. The condition may also be when the OK button 112 and the set button 113 are double-clicked simultaneously.

<Priority transfer process during quick review> Next, with reference to FIG. 10, we will explain the setting and transfer process of images to be prioritized for transfer during quick review by the imaging device 100 of this embodiment.

In S1000, the control unit 101 acquires a transfer management list from the non-volatile memory 106 or the recording medium 111. In S1001, the control unit 101 waits without proceeding to the next process until it determines that the capture button 116 has been pressed, and if it determines that the capture button 116 has been pressed, it proceeds to S1002.

In S1002, it is determined whether the OK button 112 was pressed when the capture button 116 was pressed, and if the OK button 112 was not pressed, the capture process is executed and the process proceeds to S1004, whereas if the OK button 112 was pressed, the process proceeds to S1003. In S1003, the control unit 101 performs the capture process, moves the image-related information of the captured image to the top of the transfer management list, and sets the transfer status to "waiting for priority transfer."

In S1004, the control unit 101 displays the image captured in S1003 in a quick review on the display unit 109. In S1005, the control unit 101 checks whether the image being quick reviewed is present in the transfer management list acquired in S1000, and if not, the process proceeds to S1008, and if present, the process proceeds to S1006.

In S1006, the control unit 101 acquires the transfer status of the image being quick reviewed from the transfer management list. In S1007, the control unit 101 displays on the display unit 109 an indicator corresponding to the transfer status acquired in S1006, superimposed on the image.

In S1008, the control unit 101 determines whether quick review is ongoing, and if so, proceeds to S1009, and if the quick review has ended, ends the process. Possible conditions for ending quick review here include when a predetermined time has passed since the captured image was displayed, or when the user has performed a predetermined operation. In S1009, the control unit 101 determines whether the OK button 112 and the set button 113 have been pressed simultaneously, and if they have not been pressed simultaneously, returns to S1008, and if so, proceeds to S1010.

In S1010, the control unit 101 checks whether the image being quick reviewed is in the transfer management list obtained in S1000, and if it is not in the transfer management list, the process proceeds to S1011, and if it is in the transfer management list, the process proceeds to S1012.

In S1011, the control unit 101 adds the image-related information of the image being quick reviewed to the top of the transfer management list, sets the transfer status to "waiting for priority transfer", and proceeds to S1016. In S1016, the control unit 101 displays an indicator on the display unit 109 indicating that the image is a target for priority transfer, superimposed on the captured image, resulting in the state shown in FIG. 7(c). Thereafter, the process returns to S1008, and the process from S1008 is continued during quick review.

In S1012, the control unit 101 checks the transfer management list to see if the transfer status of the image being quick reviewed is "waiting for priority transfer", and if it is "waiting for priority transfer", proceeds to S1014, otherwise proceeds to S1013. In S1013, the control unit 101 moves the image-related information of the image being quick reviewed to the top of the transfer management list, sets the transfer status to "waiting for priority transfer", and proceeds to S1016.

In S1014, the control unit 101 deletes the image-related information from the transfer management list after the transfer status of the image subject to priority transfer changes from "waiting for priority transfer" to "transfer completed." In S1015, the control unit 101 erases the indicator indicating that the image is subject to priority transfer from the display unit 109, resulting in the state shown in FIG. 7B. In this way, the setting can be released for a captured image that was set as a subject to priority transfer at the time of shooting by simultaneously pressing the OK button 112 and the set button 113 during quick review.

According to the priority transfer process in FIG. 10 described above, images to be prioritized for transfer can be quickly set with a simple operation that can be performed at the same time as issuing a shooting start command when shooting an image. This provides a means for accurately responding to the need to transfer images as quickly as possible.

Although not shown in the flowchart of FIG. 10, similarly to FIG. 9, image transfer starts when a connection with an external device is established, and the transfer status becomes "priority transfer in progress." Furthermore, when image transfer is complete, the transfer status becomes "transfer completed." The same is true for FIGS. 11, 12, 13, and 15, which will be described later.

In addition, in Figures 9 and 10, when the OK button 112 and the set button 113 are pressed simultaneously or pressed and held simultaneously, control is performed so that the image-related information set for the priority transfer target image in S911, S1011, and S1013 is placed at the top of the transfer management list. On the other hand, if a priority transfer target image is already present in the transfer management list, it may be configured to be added to the end of the existing priority transfer target images. What is important is that the priority transfer target image is registered in the list so that it is transferred before other transfer target images.

[Embodiment 2] Next, embodiment 2 will be described with reference to Figures 11 to 13.

In the above-mentioned first embodiment, the priority transfer process during playback or shooting of a single image was described. In contrast, this embodiment describes the priority transfer process during continuous shooting in which multiple images are shot. Figure 11 shows the process during image shooting.

In S1100, the control unit 101 acquires a transfer management list from the non-volatile memory 106 or the recording medium 111. In S1101, the control unit 101 waits without proceeding to the next process until it determines that the capture button 116 has been pressed, and if it determines that the capture button 116 has been pressed, the process proceeds to S1102.

In S1102, the control unit 101 determines whether continuous shooting is being performed with the shooting button 116 pressed, and if it determines that continuous shooting is being performed, the process proceeds to S1103, and if it determines that single shooting is being performed, the process proceeds to S1106. In S1103, the control unit 101 determines whether the OK button 112 is pressed, and if the OK button 112 is pressed, the process proceeds to S1105, and if it is not pressed, the process proceeds to S1110.

In S1104, the control unit 101 sets a flag to designate the series of images captured in continuous shooting as a priority transfer target. In S1105, the control unit 101 causes the image processing unit 105 to generate an image file from the image data captured in continuous shooting.

In S1106, the control unit 101 sets all images captured in continuous shooting after the flag was set as images to be transferred with priority. The control unit 101 adds the image-related information of all images captured in continuous shooting to the top of the transfer management list, sets the transfer status to "waiting for priority transfer", and proceeds to S1107.

In S1107, the control unit 101 determines whether the OK button 112 is being pressed continuously, and if it is pressed, the process proceeds to S1108, and if it is not pressed, the process proceeds to S1109. Whether the OK button 112 is pressed or not, the continuous shot images generated in S1105 are subject to priority transfer.

In S1108, the control unit 101 determines whether the shooting button 116 is being pressed continuously. If it is pressed, continuous shooting continues and the process returns to S1105. If it is not pressed, continuous shooting has ended and the process proceeds to S1109.

In S1109, the control unit 101 resets the flag set in S1104. In S1110, the control unit 101 displays a quick review of the captured image. In S1111, the control unit 101 determines whether the OK button 112 has been pressed, and if the OK button 112 has been pressed, the process proceeds to S1112, and if the OK button 112 has not been pressed, the process proceeds to S1110 and executes the capture process for a single image, not continuous capture.

In S1112, the control unit 101 sets the single-shot image as a priority transfer target. The control unit 101 adds the image-related information of the single-shot image to the top of the transfer management list, sets the transfer status to "waiting for priority transfer", and proceeds to S1110.

According to the priority transfer process of FIG. 11 described above, images to be prioritized for transfer can be set quickly with a simple operation that can be performed during continuous shooting, so that a means can be provided that accurately meets the need to transfer images as quickly as possible. For example, this can be a useful means when it is better to transfer all captured images and have the transfer destination select the images to be transferred, rather than having the photographer at the transfer source select the images to be transferred. Also, in an emergency or other case where images are taken continuously and there is no time to check the continuous shot images to determine which images should be transferred preferentially, the photographer can transfer the continuous shot images preferentially with minimal effort. These advantages are particularly evident in use cases where speed is required and the transfer destination has abundant resources for image review and editing, such as the relationship between a photographer and a news station.

Figure 12 shows the process when playing back images captured in continuous shooting.

In S1200, the control unit 101 acquires a transfer management list from the non-volatile memory 106 or the recording medium 111. In S1201, the control unit 101 waits without proceeding to the next process until it determines that the play button 114 has been pressed, and if it determines that the play button 114 has been pressed, it proceeds to S1202.

In S1202, the control unit 101 determines whether the playback image is part of an image captured by continuous shooting, and if it is determined that the image is a continuous shot image, the process proceeds to S1203, and if it is determined that the image is a single shot image, the process proceeds to S1205. The control unit 101 determines whether the image is part of an image captured by continuous shooting based on identification information added to the metadata of the continuous shot image.

In S1203, the control unit 101 determines whether the OK button 112 and the set button 113 are being pressed and held simultaneously. If they are, the process proceeds to S1204 to set the continuous shot images selected by pressing the buttons simultaneously as targets for priority transfer, and if not, the process ends.

In S1204, the control unit 101 moves the image-related information of only the selected image out of all the images captured during continuous shooting to the top of the transfer management list, and sets the transfer status to "waiting for priority transfer." There are various possible methods for selecting images to be prioritized for transfer, but for example, it is possible to set the images by simultaneously pressing buttons each time the continuous shot images are played back, similar to the designation of the images to be transferred in FIG. 9.

In S1205, the control unit 101 determines whether the OK button 112 and the set button 113 are being pressed and held simultaneously. If they are being pressed and held simultaneously, the process proceeds to S1206 to set the played image as a priority transfer target; if not, the process ends.

In S1206, the control unit 101 moves the image-related information of the played image to the top of the transfer management list and sets the transfer status to "waiting for priority transfer."

According to the priority transfer process in FIG. 12 described above, images to be prioritized for transfer can be quickly set with a simple operation while playing back images captured in continuous shooting, and only selected images can be thinned out and transferred from the images captured in continuous shooting. This allows the photographer at the transfer source to easily select and transfer the images he or she wants to transfer.

Next, a modified example of embodiment 2 will be described with reference to FIG.

This embodiment is a modified example of the process shown in FIG. 11, in which information associating continuous shot images is added during continuous shooting, and all continuous shot images are set as priority transfer targets when the OK button 112 is pressed during continuous shooting. FIG. 13 shows the priority transfer process during image shooting.

In S1300, the control unit 101 acquires a transfer management list from the non-volatile memory 106 or the recording medium 111. In S1301, the control unit 101 waits without proceeding to the next process until it determines that the capture button 116 has been pressed, and if it determines that the capture button 116 has been pressed, the process proceeds to S1302.

In S1302, the control unit 101 generates an image file from the captured image data by the image processing unit 105. If the generated image is an image captured by continuous shooting, the control unit 101 adds information that can identify that the image is part of a continuous shooting image to the metadata of the image data so that the image can be identified.

In S1303, the control unit 101 determines whether the OK button 112 has been pressed, and if the OK button 112 has been pressed, the process proceeds to S1304, and if the OK button 112 has not been pressed, the process proceeds to S1308. In S1304, the control unit 101 sets a flag to set the images captured in continuous shooting as targets for priority transfer.

In S1305, the control unit 101 searches for images that have not been set as priority transfer targets among the continuous shot images. If the search result indicates that there are images that have not been set as priority transfer targets in S1306, the process proceeds to S1307, and if there are no images that have not been set as priority transfer targets, the process proceeds to S1308.

In S1307, the control unit 101 adds image-related information for continuous-shot images that are not set as priority transfer targets to the top of the transfer management list, sets the transfer status to "waiting for priority transfer," and proceeds to S1308.

In S1308, the control unit 101 determines whether the shooting button 116 is being pressed continuously. If it is pressed, continuous shooting continues and the process returns to S1302. If it is not pressed, continuous shooting has ended and the process proceeds to S1309. In S1309, the control unit 101 resets the flag set in S1304. In S1310, the control unit 101 displays a quick review of the captured images.

According to the priority transfer process of FIG. 13 described above, images obtained by continuous shooting can be quickly set as images to be transferred preferentially all at once with a simple operation that can be performed during continuous shooting, so that a means can be provided that accurately meets the need to transfer images as quickly as possible. For example, this can be a useful means in cases where it is better to transfer all captured images and have the destination choose the images to transfer, rather than having the photographer at the transfer source choose the images to transfer. Also, in cases where an emergency is required and there is no time to check the continuous shot images when images are shot in continuous shooting to see which images should be transferred preferentially, the photographer can transfer the continuous shot images preferentially with a minimum of effort.

Next, with reference to FIG. 14, we will explain how to set the transfer order of continuous-shot images that have been set as targets for priority transfer.

1400 shows an example of a setting screen for changing the transfer order of continuous shot images set as a priority transfer target. In this embodiment, the transfer order can be selected from "order", "skip" and "center" on the setting screen shown in FIG. 14. 1401 shows continuous shot images. In the example shown, the operation when five images are shot continuously is explained. 1402 shows an example of the registered contents of the transfer management list when "order" is selected on the setting screen 1400. When "order" is selected as the priority, each image is added to the transfer management list in the order in which it was shot, and the transfer status is set to "waiting for priority transfer". The condition for setting continuous shot images as a priority transfer target is, as described above, that the OK button 112 is pressed and the shooting button 116 is pressed.

1403 shows an example of the registered contents of the transfer management list when "skip" is selected on the setting screen 1400. When "skip" is selected as the priority, images captured in continuous shooting that are odd-numbered or even-numbered are added to the front of the transfer management list. In the example shown, IMG_0001, IMG0003, and IMG_0005 are added to the front of the transfer management list, and IMG_0002 and IMG_0004 are added after them. This makes it possible to set similar images captured close together to be transferred later.

1404 shows an example of the registered contents of the transfer management list when "center" is selected on the setting screen 1400. When "center" is selected as the priority, the image in the center of the images taken in continuous shooting is added to the top of the transfer management list, the images adjacent to that image are added next in order, and the remaining images are added to the end. In the example shown, IMG_0003 is added to the top of the transfer management list, IMG_0002 and IMG_0004 adjacent to that image are added next in order on the transfer management list, and the remaining IMG_0001 and IMG_0005 are added to the end. This makes it possible, for example, to transfer preferentially images where a decisive moment was taken near the center of the continuous shooting.

As shown in FIG. 14, by setting the transfer order of the continuous shot images to be transferred with priority in advance, it is possible to transfer the images with priority in the desired order without performing another operation during the continuous shot operation. This provides a means for accurately responding to the need to transfer high priority images as quickly as possible, and can be a supplementary means for the editor at the transfer destination to select the images to be transferred.

[Embodiment 3] Next, embodiment 3 will be described with reference to FIG. 15.

This embodiment describes a process for continuing the setting of an image to be prioritized for transfer and the transfer process until the playback mode ends when an operation for setting an image to be prioritized for transfer is performed during image playback (simultaneous long press of the OK button 112 and the Set button 113).

Figure 15 shows the setting and transfer process of images to be transferred preferentially during image playback in this embodiment.

Note that steps S1500 to S1521 in FIG. 15 are similar to steps S900 to S921 in FIG. 9 of embodiment 1, so the explanation is omitted.

If a connection with the external device 200 has not been established in S1513, or after a transfer completion status such as that shown in FIG. 5(e) is displayed in S1519, processing proceeds to S1522.

In S1522, the control unit 101 determines whether the playback mode is continuing, and if the playback mode is continuing, the process proceeds to S1523, and if the playback mode has ended, the process ends. Here, the conditions for ending the playback mode are assumed to be when the capture button 116 is pressed or when the user performs a specified operation (for example, when the menu button to display a menu screen is pressed).

In S1523, the control unit 101 determines whether the OK button 112 or the set button 113 has been pressed, and if not, the process returns to S1523, and if pressed, the process proceeds to S1524.

In S1524, the control unit 101 checks whether the image being played is in the transfer management list obtained in S1500, and if it is not in the transfer management list, the process proceeds to S1525, and if it is in the transfer management list, the process proceeds to S1526.

In S1525, the control unit 101 adds the image-related information of the image being played back to the top of the transfer management list, sets the transfer status to "waiting for priority transfer", and proceeds to S1528. In S1528, the control unit 101 displays an indicator on the display unit 109 indicating that the image is a target for priority transfer, superimposed on the captured image, resulting in the state shown in FIG. 5(c). Thereafter, the process returns to S1513, and the process from S1513 is continued while in playback mode.

In S1526, the control unit 101 checks the transfer management list to see if the transfer status of the image being played is "waiting for priority transfer", and if it is "waiting for priority transfer", proceeds to S1520, otherwise proceeds to S1527. In S1527, the control unit 101 moves the image-related information of the image being played to the top of the transfer management list, sets the transfer status to "waiting for priority transfer", and proceeds to S1528.

According to the priority transfer process of FIG. 15 described above, during playback mode, images to be prioritized for transfer can be set continuously with a simple operation (for example, an operation such as pressing the OK button 112 or the set button 113 alone). This provides a means for accurately responding to the need to transfer images as quickly as possible.

Note that in FIG. 15, it has been described that when the playback mode ends in S1522, the setting of images to be transferred by priority and the transfer process are terminated, but the conditions for terminating the process may also be when a predetermined time has elapsed since the image was played back or when the user has performed a predetermined operation.

In each of the above-described embodiments, the conditions for setting the image to be transferred by priority and for starting the transfer process are a combination of two buttons (the OK button 112 and the Set button 113), but a combination of three or more buttons may also be used.

In addition, in each of the above-mentioned embodiments, examples have been described in which the transfer status of images to be transferred or images to be preferentially transferred is displayed using icons, but this is not limited to icon display, and message display, etc. may also be used. The display method includes all possible methods.
