Description

The present invention relates to an electronic device, a control method for an electronic device, and a program.

A user can display an image recorded by a digital camera or other device on a display and perform a cropping process on that image. While viewing the image displayed on the display, the user specifies the area to be cropped and then performs the cropping process. At this time, it is desirable to indicate the cropping area of the image using a frame or other display to clearly indicate the area to be cropped. Patent Document 1 discloses an image display technology that displays the border of the cropping area in a color different from the color of the displayed image in order to distinguish the cropping area from other areas.

Japanese Patent Application Laid-Open No. 2002-196745

When displaying an image to be cropped as large as possible to make it easier to check the image, it is necessary to display the image so that it touches two top and bottom edges, two left and right edges, or all four edges (top, bottom, left, right) of the display area on the display. Furthermore, the crop area is set to the inside of the cropping frame so that the displayed cropping frame does not overlap the crop area. In this case, if the crop area is specified to include the edges of the image that touch the top, bottom, left, and right edges of the display area on the display, the portion of the cropping frame 1101 indicated by dashed line 1102 will fall outside the display area 1103, as shown in Figure 11. As a result, the cropping frame will no longer be displayed on the display, making it difficult to tell how much of the image will be cropped.

Patent Document 1 does not take into consideration cases where the image to be cropped is displayed so that it touches two top and bottom edges, two left and right edges, or all four edges of the display area on such a display. Therefore, depending on the crop area specified, the cropping frame may not be displayed on the display.

The present invention was made in consideration of these circumstances, and aims to make it possible to clearly indicate the cut-out area during trimming processing.

The electronic device of the present invention comprises a display means for displaying an image, a designation means for designating a cutout area of the image, and a control means for controlling the display means to display a frame indicating the cutout area designated by the designation means together with the image, the control means controlling the display of the frame so that the inner edge of the frame becomes the boundary of the cutout area, and changing the display format of the frame when the cutout area designated by the designation means abuts a side of the image displayed on the display means.

This invention makes it possible to clearly indicate the cropping area used in the trimming process.

Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1)
1 is a diagram showing an example of the configuration of an electronic device 100 as an example of a device to which the present invention can be applied. The electronic device 100 can be configured using, for example, a personal computer.

Electronic device 100 has a CPU 101, memory 102, non-volatile memory 103, image processing unit 104, display 105, operation unit 106, recording medium interface (I/F) 107, external I/F 109, communication I/F 110, and internal bus 150. CPU 101, memory 102, non-volatile memory 103, image processing unit 104, display 105, operation unit 106, recording medium I/F 107, external I/F 109, and communication I/F 110 are connected to internal bus 150. Each unit connected to internal bus 150 can exchange data with each other via internal bus 150.

CPU 101 controls each part of electronic device 100. CPU 101 is an example of control means or image processing means. Memory 102 is, for example, RAM (volatile memory using semiconductor elements, etc.). Non-volatile memory 103 stores image data, audio data, other data, and various programs for CPU 101 to operate. Non-volatile memory 103 is, for example, a hard disk drive (HDD), solid state drive (SSD), ROM, etc. CPU 101 controls each part of electronic device 100 using memory 102 as work memory in accordance with programs stored in non-volatile memory 103, for example.

Under the control of the CPU 101, the image processing unit 104 performs various image processing operations on image data stored in the non-volatile memory 103 or recording medium 108, video signals acquired via the external I/F 109, image data acquired via the communication I/F 110, etc. The image processing operations performed by the image processing unit 104 include A/D conversion, D/A conversion, image data encoding, compression, decoding, enlargement/reduction (resizing), noise reduction, color conversion, and trimming. The image processing unit 104 may be configured with a circuit block dedicated to performing specific image processing operations. Furthermore, depending on the type of image processing, the CPU 101 may perform image processing according to a program without using the image processing unit 104.

Under the control of CPU 101, display 105 displays images and GUI screens that constitute a GUI (Graphical User Interface). Display 105 is an example of a display means. CPU 101 generates display control signals according to a program and controls each part of electronic device 100 to generate and output video signals to be displayed on display 105. Display 105 displays images based on the output video signals. Note that electronic device 100 itself may only have an interface for outputting video signals to be displayed on display 105, and display 105 may be configured as an external monitor (such as a television).

The operation unit 106 is an input device for accepting user operations. The operation unit 106 includes a character information input device such as a keyboard, a pointing device such as a mouse or touch panel, a button, a dial, a joystick, a touch sensor, a touchpad, etc. The touch panel is an input device that is configured as a planar surface overlaid on the display 105 and outputs coordinate information according to the position of contact.

The recording medium I/F 107 allows a recording medium 108 such as a memory card, CD, or DVD to be attached, and reads and writes data from and to the attached recording medium 108 under the control of the CPU 101. The external I/F 109 is an interface that connects to an external device via a wired cable or wirelessly, and is used to input and output video and audio signals. The communication I/F 110 is an interface that communicates with external devices or via a network 111, etc., and sends and receives various data such as files and commands.

Note that while an example has been described in which the electronic device in this embodiment is configured using a personal computer, the electronic device in this embodiment is not limited to this. That is, the electronic device in this embodiment may also be applied to an imaging device such as a digital camera. The present invention can also be applied when a captured image recorded on a recording medium readable by a digital camera, such as a memory card, is played back and displayed on a display such as a rear LCD device of the digital camera. Furthermore, the present invention can be applied to any device capable of displaying images, such as a PDA, a mobile phone terminal, a portable image viewer, a printer device with a display, a digital photo frame, a music player, a game console, or an e-book reader.

Next, the process of trimming an image in the electronic device 100 of embodiment 1 will be described. Below, an example of changing the color of the trimming frame when a cropping area is specified in the trimming process such that the trimming frame extends outside the display area of the display and cuts off the image will be described. Figure 2 is a flowchart showing an example of the trimming process in the electronic device 100 of this embodiment. Each process in the flowchart shown in Figure 2 is realized by the CPU 101 loading a program stored in the non-volatile memory 103 into the memory 102 and executing it.

In step S201, CPU 101 displays image 301, which is the target of the trimming process, on display 105, as shown in FIG. 3(A). For example, image 301 is displayed so that it touches all four sides (top, bottom, left, and right) of the display area on display 105. Note that image 301 may also be displayed so that it touches two top, bottom, or two left, right sides of the display area on display 105.

In step S202, the CPU 101 displays a trimming frame 302 in a first color on the display 105, as shown in FIG. 3(A).

In step S203, the CPU 101 sets the crop area 303 of the image 301 inside the cropping frame 302. Here, the inside of the cropping frame refers to the area surrounded by the cropping frame, with the inner edge of the cropping frame serving as the boundary of the area (the same applies below). In other words, by the processing of steps S202 and S203, a cropping frame indicating the crop area of the image is displayed on the display 105, with the inner edge of the frame serving as the boundary of the crop area.

In step S204, CPU 101 determines whether or not a user operation input for specifying and changing the cut-out area 303 in the trimming process has been received. If CPU 101 determines that a user operation input for specifying and changing the cut-out area 303 has been received (YES in step S204), processing proceeds to step S205. On the other hand, if CPU 101 determines that a user operation input for changing the cut-out area 303 has not been received (NO in step S204), processing proceeds to step S206.

In step S205, the CPU 101 performs a trimming frame update process. The trimming frame update process will be described later. After the trimming frame update process in step S205 is completed, the CPU 101 returns to step S204.

In step S206, CPU 101 determines whether or not a user operation input for finalizing cut-out area 303 for the trimming process has been received. If CPU 101 determines that a user operation input for finalizing cut-out area 303 has been received (YES in step S206), processing proceeds to step S207. On the other hand, if CPU 101 determines that a user operation input for finalizing cut-out area 303 has not been received (NO in step S206), processing returns to step S204.

In step S207, the CPU 101 executes a process to crop the image 301 based on the specified crop area 303. After cropping the image 301, the CPU 101 ends the cropping process.

Figure 4 is a flowchart showing the trimming frame update process in embodiment 1, which is executed in step S205 of Figure 2. Each process in the flowchart shown in Figure 4 is realized by the CPU 101 loading a program stored in non-volatile memory 103 into memory 102 and executing it.

In step S401, the CPU 101 changes the position and shape of the crop area 303 in the trimming process in accordance with input from a user operation.

In step S402, CPU 101 determines whether cutout region 303 has been specified at an angle relative to display 105. If the boundary of cutout region 303 includes an edge that is parallel to an edge of the display area on display 105, CPU 101 determines that the cutout region has been specified without an angle; otherwise, CPU 101 determines that the cutout region has been specified at an angle. If CPU 101 determines that cutout region 303 has been specified at an angle (YES in step S402), processing proceeds to step S403. On the other hand, if CPU 101 determines that cutout region 303 has been specified without an angle (NO in step S402), processing proceeds to step S404.

In step S403, the CPU 101 displays the trimming frame 302 in the first color on the display 105. The CPU 101 then ends the trimming frame update process and returns to the processing of the flowchart shown in Figure 2.

In step S404, CPU 101 determines whether the image edge of image 301 is included in cut-out area 303. Specifically, CPU 101 determines whether the portion where the side of the display area on display 105 and the side of image 301 meet is included in cut-out area 303. For example, in step S401, when cut-out area 303 is changed to the position of cut-out area 305 as shown in FIG. 3(B), it is determined that the portion where the side of the display area on display 105 and the side of image 301 meet is included in cut-out area 305. If CPU 101 determines that the portion where the side of the display area on display 105 and the side of image 301 meet is included in the specified cut-out area 305 after the change (YES in step S404), processing proceeds to step S405. On the other hand, if the CPU 101 determines that the area where the edge of the display area on the display 105 meets the edge of the image 301 is not included in the specified crop area 305 after the change (NO in step S404), the process proceeds to step S403.

In step S405, the CPU 101 displays the trimming frame 304 on the display 105 in a second color different from the first color, as shown in FIG. 3(B). The CPU 101 then ends the trimming frame update process and returns to the processing of the flowchart shown in FIG. 2.

In this way, if the portion where the edge of the display area on the display 105 meets the edge of the image 301 is included in the crop area 305, in step S405 of FIG. 4, processing is performed to display the trimming frame 304 in a second color different from the first color. Here, by displaying the trimming frame 304 in a color different from the color at the start of the trimming process, it is possible to indicate to the user that part of the trimming frame 304 has moved outside the display area on the display 105 and is not being displayed.

Note that in step S405 of FIG. 4, CPU 101 performs processing to display trimming frame 304 in a second color different from the first color, but this is not limited to this. CPU 101 may perform processing to display trimming frame 304 in a state different from that at the start of the trimming process, such as a dashed or dotted line. Furthermore, processing may be performed to display trimming frame 304 by blinking. Alternatively, processing may be performed to change the thickness of trimming frame 304. Furthermore, rather than changing the color of the entire trimming frame 304, the display form of only the four sides of trimming frame 304 that are in contact with the edge of the image may be changed. Furthermore, processing may be performed to display trimming frame 304 using an appropriate combination of these display forms. As shown here, by changing the display form of trimming frame 304 from that at the start of the trimming process, it is possible to indicate to the user that part of trimming frame 304 is outside the display area of display 105 and is not displayed.

Electronic device 100 performs the processing shown in Figures 2 and 4, and changes the display format of trimming frame 304 only if part of trimming frame 304 is outside the display area of display 105 and is not displayed. In this way, the representation of the trimming frame is changed when part of the trimming frame is outside the display area of display 105, making it possible to clearly show the user that the cut-out area 305 used in the trimming process includes the edge of image 301.

(Embodiment 2)
In the second embodiment, an example will be described in which, when a cropping area is specified such that the cropping frame extends outside the display area of the display, the cropping area is changed from inside to outside the cropping frame. Here, "outside the cropping frame" refers to the area surrounded by the cropping frame, with the outer edge of the cropping frame as the boundary of the area (the same applies hereinafter).

The configuration of the electronic device 100 in embodiment 2 is similar to the configuration of the electronic device 100 in embodiment 1, and therefore a description thereof will be omitted. Furthermore, the trimming process of the electronic device 100 in embodiment 2 is similar to the trimming process in embodiment 1 described with reference to FIG. 2, except for the trimming frame update process (step S205 in FIG. 2), and therefore a description of the similar processes will be omitted. Below, the trimming frame update process in embodiment 2 will be described.

Figure 5 is a flowchart showing the process of updating the trimming frame in embodiment 2. Each process in the flowchart shown in Figure 5 is realized by the CPU 101 loading a program stored in the non-volatile memory 103 into the memory 102 and executing it.

In step S501, the CPU 101 changes the position and shape of the crop area 303 in the trimming process in accordance with input from a user operation.

In step S502, CPU 101 determines whether cutout area 303 has been specified in a tilted state with respect to display 105. If CPU 101 determines that cutout area 303 has been specified in a tilted state (YES in step S502), processing proceeds to step S503. On the other hand, if CPU 101 determines that cutout area 303 has been specified in a non-tilted state (NO in step S502), processing proceeds to step S504.

In step S503, CPU 101 sets crop area 303 of image 301 inside cropping frame 302. That is, CPU 101 sets the area surrounded by cropping frame 302, with the inner edge of cropping frame 302 as the boundary of the area, as the crop area of image 301. CPU 101 then ends the cropping frame update process and returns to the processing of the flowchart shown in Figure 2.

In step S504, CPU 101 determines whether the image edge of image 301 is included in cut-out region 303. Specifically, CPU 101 determines whether the portion where the side of the display area on display 105 and the side of image 301 meet is included in cut-out region 303. For example, in step S501, when cut-out region 303 is changed to the position of cut-out region 601 as shown in FIG. 6, it is determined that the portion where the side of the display area on display 105 and the side of image 301 meet is included in cut-out region 601. If CPU 101 determines that the portion where the side of the display area on display 105 and the side of image 301 meet is included in the specified cut-out region 601 after the change (YES in step S504), processing proceeds to step S505. On the other hand, if the CPU 101 determines that the area where the edge of the display area on the display 105 meets the edge of the image 301 is not included in the specified crop area 601 after the change (NO in step S504), the process proceeds to step S503.

In step S505, the CPU 101 sets the crop area 601 of the image 301 outside the trimming frame 602, as shown in FIG. 6. That is, the CPU 101 sets the area surrounded by the trimming frame 602, with the outer edge of the trimming frame 602 as the boundary of the area, as the crop area of the image 301. The CPU 101 then ends the trimming frame update process and returns to the processing of the flowchart shown in FIG. 2.

In this way, if the portion where the edge of the display area on the display 105 meets the edge of the image 301 is included in the clipping area 601, processing is performed in step S505 to change the clipping area 601 from inside to outside the trimming frame 602. By changing the clipping area 601 from inside to outside the trimming frame 602, all of the trimming frame 602 is displayed on the display 105, preventing a state in which part of the trimming frame 602 is not displayed. Alternatively, instead of changing the clipping area 601 for the entire trimming frame 304 from inside to outside the trimming frame 602, the clipping area 601 may be changed from inside to outside only for the four edges of the trimming frame 304 that are in contact with the edge of the image. Furthermore, in combination with embodiment 1, the display format of the edge of the clipping area 601 that has been changed from inside to outside may be changed to clearly notify the user that the boundary has been changed from inside to outside.

Electronic device 100 performs the processing shown in Figures 2 and 5, and changes clipping area 601 from inside to outside trimming frame 602 only if the area where the edge of the display area on display 105 meets the edge of image 301 is included in clipping area 601. This causes all parts of trimming frame 602 to be displayed on display 105, clearly indicating the clipping area used in the trimming process and clearly indicating to the user that clipping area 601 includes the entire edge of image 301.

(Embodiment 3)
In embodiment 3, an example is described in which, when a cropping area is specified such that the cropping frame extends outside the display area on the display and is cut off, the cropping frame is hidden and other areas of the image other than the cropping area are displayed in a specified color.

The configuration of the electronic device 100 in embodiment 3 is similar to the configuration of the electronic device 100 in embodiment 1, and therefore a description thereof will be omitted. Furthermore, the trimming process of the electronic device 100 in embodiment 3 is similar to the trimming process in embodiment 1 described with reference to FIG. 2, except for the trimming frame update process (step S205 in FIG. 2), and therefore a description of the similar processes will be omitted. Below, the trimming frame update process in embodiment 3 will be described.

Figure 7 is a flowchart showing the process of updating the trimming frame in embodiment 3. Each process in the flowchart shown in Figure 7 is realized by the CPU 101 loading a program stored in the non-volatile memory 103 into the memory 102 and executing it.

In step S701, the CPU 101 changes the position and shape of the crop area 303 in the trimming process in accordance with input from a user operation.

In step S702, CPU 101 determines whether or not cut-out area 303 has been specified in a tilted state with respect to display 105. If CPU 101 determines that cut-out area 303 has been specified in a tilted state (YES in step S702), processing proceeds to step S703. On the other hand, if CPU 101 determines that cut-out area 303 has been specified in a non-tilted state (NO in step S702), processing proceeds to step S705.

In step S703, CPU 101 displays image 301 on display 105 in the same state as at the start of the trimming process, without changing the color of image 301.

In step S704, the CPU 101 displays the trimming frame 302 in the first color on the display 105. The CPU 101 then ends the trimming frame update process and returns to the processing of the flowchart shown in Figure 2.

In step S705, CPU 101 determines whether the image edge of image 301 is included in cut-out region 303. Specifically, CPU 101 determines whether the portion where the side of the display area on display 105 and the side of image 301 meet is included in cut-out region 303. For example, in step S701, when cut-out region 303 is changed to the position of cut-out region 801 as shown in FIG. 8, it is determined that the portion where the side of the display area on display 105 and the side of image 301 meet is included in cut-out region 801. If CPU 101 determines that the portion where the side of the display area on display 105 and the side of image 301 meet is included in the specified cut-out region 801 after the change (YES in step S705), processing proceeds to step S706. On the other hand, if the CPU 101 determines that the area where the edge of the display area on the display 105 meets the edge of the image 301 is not included in the specified crop area 801 after the change (NO in step S705), processing proceeds to step S703.

In step S706, the CPU 101 displays the other areas 802 of the image 301 other than the cut-out area 801 in a predetermined color, as shown in FIG. 8. For example, the CPU 101 displays the other areas 802 on the display 105 with a semi-transparent gray color overlaid on the image 301.

In step S707, the CPU 101 hides the trimming frame 302. The CPU 101 then ends the trimming frame update process and returns to the processing of the flowchart shown in Figure 2.

In this way, if the portion where the edge of the display area on display 105 meets the edge of image 301 is included in cutout area 801, processing is performed in step S707 to hide trimming frame 302. By hiding trimming frame 302, it is possible to prevent a state in which part of trimming frame 302 is not displayed. Furthermore, if the portion where the edge of the display area on display 105 meets the edge of image 301 is included in cutout area 801, processing is performed in step S706 to change other areas 802 of image 301 to a predetermined color. Here, other areas 802 are displayed in the predetermined color only when the portion where the edge of the display area on display 105 meets the edge of image 301 is included in cutout area 801, so the entire image does not always become difficult to see.

Electronic device 100 performs the processing shown in Figures 2 and 7, and changes the other area 802 to a predetermined color and hides trimming frame 302 only when the area where the edge of the display area on display 105 meets the edge of image 301 is included in cutout area 801. This makes it possible to clearly indicate the cutout area in the trimming process, and clearly shows the user that cutout area 801 includes the entire edge of image 301.

(Embodiment 4)
In the fourth embodiment, an example will be described in which, when the entire image is designated as the cut-out region for the trimming process, the cut-out region is changed from inside to outside the trimming frame.

The configuration of the electronic device 100 in embodiment 4 is similar to the configuration of the electronic device 100 in embodiment 1, and therefore a description thereof will be omitted. Furthermore, the trimming process of the electronic device 100 in embodiment 4 is similar to the trimming process in embodiment 1 described with reference to FIG. 2, except for the trimming frame update process (step S205 in FIG. 2), and therefore a description of the similar processes will be omitted. Below, the trimming frame update process in embodiment 4 will be described.

Figure 9 is a flowchart showing the process of updating the trimming frame in embodiment 4. Each process in the flowchart shown in Figure 9 is realized by the CPU 101 loading a program stored in the non-volatile memory 103 into the memory 102 and executing it.

In step S901, the CPU 101 changes the position and shape of the crop area 303 in the trimming process in accordance with input from a user operation.

In step S902, CPU 101 determines whether cut-out region 303 has been specified to include all parts of image 301. For example, in step S901, if cut-out region 303 is changed to the position of cut-out region 1001 as shown in FIG. 10, it is determined that all parts of image 301 are included in cut-out region 1001. If CPU 101 determines that cut-out region 1001 has been specified to include all parts of image 301 (YES in step S902), processing proceeds to step S903. On the other hand, if CPU 101 determines that cut-out region 1001 has not been specified to include all parts of image 301 (NO in step S902), processing proceeds to step S904.

In step S903, the CPU 101 sets the crop area 1001 of the image 301 outside the trimming frame 1002. That is, the CPU 101 sets the area surrounded by the trimming frame 1002, with the outer edge of the trimming frame 1002 as the boundary of the area, as the crop area of the image 301. The CPU 101 then ends the trimming frame update process and returns to the processing of the flowchart shown in Figure 2.

In step S903, CPU 101 sets crop area 303 of image 301 inside cropping frame 302. That is, CPU 101 sets the area surrounded by cropping frame 302, with the inner edge of cropping frame 302 as the boundary of the area, as the crop area of image 301. CPU 101 then ends the cropping frame update process and returns to the processing of the flowchart shown in Figure 2.

In this way, when the crop area 1001 is specified to include all parts of the image 301, the processing in step S903 is performed to change the crop area 1001 from inside to outside the cropping frame 1002. By changing the crop area 1001 from inside to outside the cropping frame 1002, all parts of the cropping frame 1002 are displayed on the display 105, thereby preventing a situation in which some or all parts of the cropping frame 1002 are not displayed.

Electronic device 100 performs the processing shown in Figures 2 and 10, and changes crop area 1001 from inside to outside trimming frame 1002 only if crop area 1001 is specified to include all parts of image 301. This makes it possible to clearly indicate the crop area used in the cropping process, and clearly shows the user that crop area 1001 includes all parts of image 301.

In each of the above-described embodiments, in step S207 of FIG. 2, electronic device 100 performs processing to crop the image based on the crop area. However, this is not limited to this, and electronic device 100 may notify another device of a cropping processing instruction that includes information related to the specified crop area, and the device that receives the notification may perform processing to crop the image based on the information related to the crop area.

Furthermore, the various controls described in the above embodiments as being performed by the CPU 101 may be performed by a single piece of hardware, or the entire device may be controlled by multiple pieces of hardware (e.g., multiple processors or circuits) sharing the processing.

While the present invention has been described in detail based on preferred embodiments, the present invention is not limited to these specific embodiments, and various forms within the scope of the gist of the invention are also included in the present invention. Furthermore, each of the above-described embodiments merely represents one embodiment of the present invention, and each embodiment can be combined as appropriate.
