Description

The present invention relates to a technique capable of switching an operation mode during shooting .

When shooting video with an imaging device such as a digital camera, if the processing load of the imaging unit or the power consumption of the battery increases, these may generate heat and cause the inside of the device to become hot. For this reason, some imaging devices such as digital cameras are equipped with a temperature rise mitigation function that reduces the processing load of the imaging unit and the power consumption of the battery to prevent the inside of the device from becoming too hot.

The temperature rise mitigation function (eco mode) reduces the processing load of the imaging unit and the power consumption of the battery by lowering the frame rate and resolution of the image when standby for shooting compared to when shooting (Patent Document 1).

JP 2000-253280 A

However, when outputting video to an external device, recording may be performed on the external recording device even when the camera is on standby. In such cases, if the image quality is degraded, video that the user does not intend may be recorded.

In addition, when switching from standby to shooting, the video may be recorded in a temporarily stopped state, or the time code output may stop, which may result in the recording of footage that the user does not intend.

The present invention was made in consideration of the above problems, and its purpose is to realize a technology that allows the user to record the video they want to record on an external device while reducing the temperature inside the device.

In order to solve the above problems and achieve the object, the present invention provides an imaging device for a system having an imaging device and an external device that displays an image being output from the imaging device and allows a user to select whether or not to record the image, the imaging device having a display means for displaying an image obtained by the imaging means on a display unit visible to the user who performs a recording operation of the external device , an output means for outputting the image obtained by the imaging means to the external device, a processing means capable of switching to and executing either a first operation mode in which processing at the time of imaging of the image is reduced while waiting to shoot compared to during shooting, or a second operation mode in which processing at the time of imaging of the image is the same regardless of whether waiting to shoot or during shooting, and a control means for controlling the imaging device to execute a first operation of not displaying the image on the display unit and outputting it to the external device, and a second operation of displaying the image on the display unit and outputting it to the external device, wherein the control means executes the first operation while waiting to shoot in the first operation mode , executes the second operation while shooting in the first operation mode, and executes the second operation in the second operation mode .

The present invention allows the user to record the video they want on an external device while reducing the temperature inside the device.

The following embodiments are described in detail with reference to the attached drawings. Note that the following embodiments do not limit the invention according to the claims. Although the embodiments describe multiple features, not all of these multiple features are necessarily essential to the invention, and multiple features may be combined in any manner. Furthermore, in the attached drawings, the same reference numbers are used for the same or similar configurations, and duplicate explanations are omitted.

<Device configuration> The functions and appearance of the digital camera of this embodiment will be explained with reference to Figures 1 and 2.

1, which shows the appearance of the rear of the digital camera 100 of this embodiment, the rear display unit 101 is composed of a liquid crystal display panel (LCD) that displays images and various information. The shutter button 102 is an operation unit for issuing shooting instructions. The mode switching button 103 is an operation unit for switching between various modes. The connector 107 is an interface that connects the connection cable 108 and the digital camera 100. The operation unit 104 is an operation unit composed of various switches, buttons, touch panels, and other operation members that accept various operations from the user. The controller wheel 106 is a rotatable electronic dial included in the operation unit 104. The power switch 105 is an operation unit that switches the power on and off. The recording medium 109 is a recording medium such as a memory card or a hard disk. The recording medium slot 110 is a slot for storing the recording medium 109. The recording medium 109 stored in the recording medium slot 110 can communicate with the digital camera 100, and data can be written and read. The lid 111 is a lid for the recording medium slot 110. FIG. 1 shows the state in which the lid 111 has been opened and a portion of the recording medium 109 has been removed and exposed from the recording medium slot 110.

In FIG. 2 showing the internal configuration of the digital camera 100 of this embodiment, the photographing lens 203 is a lens group including a zoom lens and a focus lens. The shutter 204 has an aperture function. The imaging unit 205 is an imaging element composed of a CCD, CMOS, or the like that converts an optical image of a subject into an electrical signal. The A/D converter 206 converts an analog signal into a digital signal. The A/D converter 206 is used to convert the analog signal output from the imaging unit 205 into a digital signal. The barrier 202 covers the imaging system of the digital camera 100 including the photographing lens 203, thereby preventing the imaging system including the photographing lens 203, shutter 204, and imaging unit 205 from becoming dirty or damaged.

The image processing unit 207 performs predetermined pixel interpolation, resizing such as reduction, and color conversion processing on the data from the A/D converter 206 or the data from the memory control unit 209. The image processing unit 207 also performs predetermined calculation processing using the captured image data, and the system control unit 201 performs exposure control and distance measurement control based on the obtained calculation results. This allows TTL (through-the-lens) type AF (autofocus) processing, AE (automatic exposure) processing, and EF (flash pre-flash) processing to be performed. The image processing unit 207 also performs predetermined calculation processing using the captured image data, and TTL type AWB (auto white balance) processing based on the obtained calculation results.

The output data from the A/D converter 206 is written to the memory 210 via the image processing unit 207 and the memory control unit 209, or directly via the memory control unit 209. The memory 210 stores image data obtained by the imaging unit 205 and converted into digital data by the A/D converter 206, and image data to be displayed on the rear display unit 101. The memory 210 has a storage capacity sufficient to store a predetermined number of still images and a predetermined period of video and audio.

The memory 210 also serves as a memory for image display (video memory). The D/A converter 208 converts the image display data stored in the memory 210 into an analog signal and supplies it to the rear display unit 101. In this way, the display image data written to the memory 210 is displayed by the rear display unit 101 via the D/A converter 208. The rear display unit 101 performs display according to the analog signal from the D/A converter 208 on a display device such as an LCD. A digital signal that has been A/D converted once by the A/D converter 206 and stored in the memory 210 is converted to analog in the D/A converter 208 and sequentially transferred to and displayed on the rear display unit 101, thereby displaying a live view image.

The non-volatile memory 213 is an electrically erasable and programmable memory, such as an EEPROM. The non-volatile memory 213 stores constants and programs for the operation of the system control unit 201. The programs referred to here are programs for executing the various flowcharts described later in this embodiment.

The system control unit 201 controls the entire digital camera 100. By executing the programs stored in the non-volatile memory 213 described above, each process of this embodiment, which will be described later, is realized. 212 is a system memory, which uses a RAM. Constants and variables for the operation of the system control unit 201, programs read from the non-volatile memory 213, etc. are deployed in the system memory 212. The system control unit 201 also performs display control by controlling the memory 210, the D/A converter 208, the rear display unit 101, etc.

The system timer 211 is a timing unit that measures the time used for various controls and the time of the built-in clock.

The mode switching button 103, the first shutter switch 102a, the second shutter switch 102b, and the operation unit 104 are operation means for inputting various operation instructions to the system control unit 201.

The mode switching button 103 switches the operation mode of the system control unit 201 to one of still image shooting mode, video recording mode, playback mode, etc. Modes included in the still image shooting mode include auto mode, auto scene determination mode, manual mode, various scene modes with scene-specific shooting settings, program AE mode, custom mode, etc. The mode switching button 103 can directly switch to one of these modes. Alternatively, after switching to the shooting mode selection screen with the mode switching button 103, the mode can be switched by selecting one of the options corresponding to each shooting mode displayed on the shooting mode selection screen using other operating members. Similarly, the video recording mode can include multiple modes. The video recording mode also includes an eco mode that reduces the temperature rise due to heat generation inside the digital camera 100.

The first shutter switch 102a is turned on by half-pressing the shutter button 102 provided on the digital camera 100 (instruction to prepare for shooting) during operation and generates a first shutter switch signal SW1. The first shutter switch signal SW1 starts preparation processes for shooting, such as AF processing, AE processing, AWB processing, and EF processing.

The second shutter switch 102b is turned on when the shutter button 102 is fully pressed (photographing instruction) and generates a second shutter switch signal SW2. The system control unit 201 starts a series of photographing processes, from reading the signal from the imaging unit 205 to writing image data to the recording medium 109, based on the second shutter switch signal SW2.

The operating members of the operating unit 104 are assigned appropriate functions for each scene by selecting and operating various functional icons displayed on the rear display unit 101, and act as various function buttons. Examples of function buttons include an end button, a back button, an image forward button, a jump button, a filter button, and an attribute change button. For example, when the menu button is pressed, a menu screen in which various settings can be made is displayed on the rear display unit 101. The user can intuitively make various settings using the menu screen displayed on the rear display unit 101, the four directional buttons (up, down, left, and right), and the SET button.

The controller wheel 106 is a rotatable operating member included in the operating unit 104, and is used together with the directional buttons to indicate a selection item. When the controller wheel 106 is rotated, an electrical pulse signal is generated according to the amount of rotation, and the system control unit 201 controls each unit of the digital camera 100 based on this pulse signal. This pulse signal makes it possible to determine the angle at which the controller wheel 106 is rotated and how many times it has rotated. The controller wheel 106 may be any operating member that can detect a rotation operation. For example, the controller wheel 106 may be a dial operating member that rotates itself in response to a user's rotation operation to generate a pulse signal. Alternatively, the controller wheel 106 may be an operating member made of a touch sensor that does not rotate itself but detects the rotation of the user's finger on the controller wheel 106 (a so-called touch wheel).

The power supply control unit 214 is composed of a battery detection circuit, a DC-DC converter, a switch circuit that switches between blocks to which electricity is applied, and the like, and detects whether a battery is installed, the type of battery, and the remaining battery power. The power supply control unit 214 also controls the DC-DC converter based on the detection results and instructions from the system control unit 201, and supplies the necessary voltage to each unit, including the recording medium 109, for the necessary period of time.

The power supply unit 215 consists of a primary battery such as an alkaline battery or a lithium battery, a secondary battery such as a NiCd battery, a NiMH battery, or a lithium ion battery, an AC adapter, etc. The recording medium I/F 216 is an interface with a recording medium 109 such as a memory card or a hard disk. The recording medium 109 is a recording medium such as a memory card for recording captured images, and is composed of a semiconductor memory, a magnetic disk, etc.

The communication unit 217 is communicatively connected to an external device via a wireless antenna or a wired cable, and transmits and receives video and audio. The communication unit 217 can also connect to a wireless LAN (Local Area Network) or the Internet. The communication unit 217 can transmit image data (including live view images) captured by the imaging unit 205 and image files recorded on the recording medium 109 to an external device, and can also receive image data and various other information from an external device. The communication unit 217 is also capable of short-range wireless communication such as Bluetooth (registered trademark) and Bluetooth (registered trademark) Low Energy.

The attitude detection unit 218 detects the attitude of the digital camera 100 with respect to the direction of gravity. Depending on the attitude detected by the attitude detection unit 218, it is possible to determine whether the image captured by the imaging unit 205 was taken with the digital camera 100 held horizontally or vertically. The system control unit 201 can add information about the attitude detected by the attitude detection unit 218 to image data captured by the imaging unit 205, or rotate and store the image data. An acceleration sensor, a gyro sensor, or the like can be used as the attitude detection unit.

The external output I/F 219 supplies the video data (still image data or video data) for display or recording stored in the memory 210 to the external device 300 as a digital signal. For example, it outputs a video signal, an audio signal, and a control signal according to a communication protocol conforming to the HDMI (registered trademark) (High-Definition Multimedia Interface) standard. In this way, the video data for display or recording written in the memory 210 is displayed or recorded in the external device 300. The external device 300 is, for example, a display device or a recording device compatible with 4K or 8K. Note that the external output I/F 219 is not limited to HDMI (registered trademark), and may be SDI or USB.

The rear display unit 101 is also provided with a touch panel 104a having a touch sensor capable of detecting touch operations on the display screen. The touch panel 104a is an input device that is configured to be planar and superimposed on the display screen of the rear display unit 101, and outputs coordinate information according to the touched position. The system control unit 201 can detect the following operations on the touch panel 104a: Touching the touch panel 104a with a finger or pen (touch down); Touching the touch panel 104a with a finger or pen (touch on); Moving the touch panel 104a while touching it with a finger or pen (move); Releasing the finger or pen that was touching the touch panel 104a (touch up); A state in which nothing is touching the touch panel 104a (touch off). Touching down and touching up the touch panel 104a with a finger or pen in succession is called a tap. These operations and the position coordinates where the finger or pen touches the touch panel are notified to the system control unit 201, which determines what operation has been performed on the touch panel based on the notified information. For a move, the direction of movement of the finger or pen moving on the touch panel 104a can also be determined for each vertical and horizontal component of the touch panel 104a based on the change in the position coordinates. In addition, when the touch panel 104a is touched down, then touched up after a move of a predetermined distance or more, it is considered that a drop has been performed after a drag (drag and drop). The touch panel 104a may be any of various types of touch panels, such as a resistive film type, a capacitive type, a surface acoustic wave type, an infrared type, an electromagnetic induction type, an image recognition type, or an optical sensor type.

The present invention can also be applied to a control device that communicates with an imaging device (including a network camera) via wired or wireless communication, and remotely controls the imaging device, rather than being limited to the imaging device itself. Examples of devices that remotely control an imaging device include a smartphone, a tablet PC, and a desktop PC. The imaging device can be remotely controlled by sending commands from the control device to the imaging device to perform various operations and settings based on operations or processes performed on the control device. In addition, a live view image captured by the imaging device may be received via wired or wireless communication and displayed on the control device.

In the present embodiment, the present invention has been described with reference to a digital camera as an example, but is not limited to this example. In other words, the present invention can be applied to any device that has a display and can transfer data to an external device, such as a PDA (Personal Digital Assistant), 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.

<Operation Description> Next, the operation of the digital camera 100 of this embodiment will be described with reference to FIG. 3.

In the digital camera 100 of this embodiment, the user can switch the eco mode on or off via the operation unit 104, and the operation can be switched and executed depending on whether the eco mode is on or off. The eco mode is a temperature rise mitigation function that reduces the processing during image capture during standby compared to during image capture in order to suppress the processing load of the imaging unit 205 of the digital camera 100 and the power consumption of the battery in the video recording mode and reduce the temperature rise due to heat generation inside the device. In detail, when the eco mode is on, the frame rate and resolution of the video output from the imaging unit 205 during standby compared to during image capture (video recording). In addition, when a video signal is output to the external device 300 via the external output I/F 219, a video signal is generated so that the frame rate and resolution of the video are the same during standby and video recording, and is output to the external device 300. The reason for this is that if the frame rate and resolution of the video signal output to the external device 300 change, reconnection to the external device 300 is required each time the frame rate and resolution of the video signal change. For example, if the resolution of the video signal when standby for shooting is 1920x1080 and the resolution of the video signal when recording a movie is 3840x2160, the video signal is resized (enlarged) twice as long vertically and horizontally when standby for shooting and output to external device 300; if the frame rate of the video signal when standby for shooting is 30p and the resolution of the video signal when recording a movie is 60p, the frame rate is increased from 30p to 60p when standby for shooting and output to external device 300.

Figure 3 shows an example of the external output (information display, time code) and the operating state of the rear display unit 101 according to the setting state of the eco mode of the digital camera 100 of this embodiment.

The image display can be in a state where an image is displayed on the rear display unit 101 or a state where an image is not displayed.

The external output can be in a state where a video signal is output to the external device 300 via the external output I/F 219, or in a state where it is not output.

When outputting information to an external device, OSD (On Screen Display) information showing the status of the digital camera 100 at the time of shooting, such as shooting settings and remaining battery power, is displayed superimposed on the video signal, or only the video is displayed.

The time code may or may not be output to the external device 300 via the external output I/F 219. The time code is "hour, minute, second, frame" information that is recorded for each frame of the video signal when recording a moving image.

[Embodiment 1]
First, with reference to FIG. 3A, a control example for preventing recording unintended by the user from being performed by the external device 300 when the eco mode is on will be described.

The user can set the display of information during external output to on (enabled) or off (disabled).

No. 1 and 2 in FIG. 3(a) are when the eco mode is off, and the video signal and time code are output to the rear display unit 101 and the external device 300.

When the information display of the external output is on (No. 1), OSD information is superimposed on the video signal and output to the external device 300. Note that the user may operate the operation unit 104 to temporarily turn off the information display (output only the video signal).

When the information display of the external output is off (No. 2), only the video signal is output to the external device 300.

No. 3 and 4 in FIG. 3(a) are when the eco mode is on, the rear display unit 101 is not displayed, and a video signal is output only to the external device 300. In addition, regardless of whether the setting for displaying information on the external output is on or off, a video signal with OSD information superimposed thereon is output to the external device 300.

By controlling in this way, when eco mode is on, the frame rate and resolution of the video signal differ between when standby for shooting and when recording video, so the user can be prompted not to record unintended video on the external device 300.

When eco mode is on, the user may be prevented from setting the information display for external output, and the setting may be forcibly turned on. Also, time code is not output to prevent unintended recording from being performed on the external device 300.

When switching between standby and video recording, the frame rate and resolution of the video output from the imaging unit 205 are changed, so the image display update is temporarily halted. However, by not stopping the external output of the video signal and time code, the time code can maintain its continuity, so the time code can continue to be output even while standby is in progress (so-called free run).

According to this embodiment, when the eco mode is on, the rear display unit 101 is hidden, making it difficult for the user to record on the external device 300, and thus the user can be urged not to record video on the external device 300 at a frame rate or resolution that the user does not intend.

[Embodiment 2]
Next, with reference to FIG. 3B, a control example for preventing recording unintentionally by the user from being performed on the external device 300 during standby for photographing will be described.

No. 1, 2, 3, and 4 in FIG. 3(b) are when the eco mode is off, and the video signal and time code are output to the rear display unit 101 and the external device 300 regardless of whether the camera is in standby or recording video.

When the information display of the external output is on (No. 1, 3), OSD information is superimposed on the video signal and output to the external device 300. Note that the user may operate the operation unit 104 to temporarily turn off the information display (output only the video signal).

When the information display of the external output is off (No. 2, 4), only the video signal is output to the external device 300.

No. 5 and 6 in FIG. 3(b) are when the eco mode is on, and during standby for shooting, the rear display unit 101 is not displayed and a video signal is output only to the external device 300. In addition, regardless of whether the setting for displaying information on the external output is on or off, a video signal with OSD information superimposed is output to the external device 300.

By controlling in this way, the frame rate and resolution of the video signal differ when standby is in progress and when video is being recorded, so the user can be urged not to record unintended video on the external device 300.

When eco mode is on, the time code is not output to prevent unintended recording on the external device 300.

During video recording, the frame rate and resolution of the video are user-set, so the user may perform the recording on the external device 300. For this reason, the user may be able to operate the operation unit 104 to temporarily turn off the information display (output only the video signal). In addition, the time code may be counted up only while the video is being recorded (so-called recording run).

When switching between standby and video recording, the frame rate and resolution of the video output from the imaging unit 205 are changed, so the image display update is temporarily halted. However, by not stopping the external output of the video signal and time code, the time code can maintain its continuity, so the time code can continue to be output even while standby is in progress (so-called free run).

No. 7 and 8 in FIG. 3(b) show the case where the eco mode is on and video is being recorded, so the frame rate and resolution of the video are set by the user, and the video signal and time code are output to the rear display unit 101 and the external device 300.

When the information display of the external output is on (No. 7), OSD information is superimposed on the video signal and output to the external device 300. Note that the user may operate the operation unit 104 to temporarily turn off the information display (output only the video signal).

When the information display of the external output is off (No. 8), only the video signal is output to the external device 300.

According to this embodiment, when the eco mode is on and the camera is on standby for shooting, the rear display unit 101 is hidden, making it difficult for the user to record on the external device 300, and thus urging the user not to record video on the external device 300 at a frame rate or resolution that the user does not intend.

[Embodiment 3]
Next, with reference to FIG. 3C, a control example for preventing recording unintended by the user from being performed by the external device 300 in the moving image recording mode will be described.

No. 1, 2, 3, 4, 5, 6, 7, and 8 in FIG. 3(c) are when the eco mode is off, and the video signal and time code are output to the rear display unit 101 and the external device 300 regardless of whether the camera is in standby or video recording mode, or in still image shooting mode or video recording mode.

When the information display of the external output is on (No. 1, 3, 5, 7), OSD information is superimposed on the video signal and output to the external device 300. Note that the user may operate the operation unit 104 to temporarily set the information display to off (output only the video signal).

When the information display of the external output is off (No. 2, 4, 6, 8), only the video signal is output to the external device 300.

Nos. 9, 10, 11, and 12 in FIG. 3(c) are when eco mode is on, and in still image shooting mode, the purpose of external output is considered to be not recording on the external device 300 but checking the image on the external device 300. Therefore, while the frame rate and resolution of the video differ from those during video recording when waiting to shoot, the video signal and time code are output to the rear display unit 101 and the external device 300 in the same way as when eco mode is off.

No. 13, 14, 15, and 16 in FIG. 3(c) are when the eco mode is on, and in video recording mode, the same operations as No. 5, 6, 7, and 8 in FIG. 3(b) are performed.

According to this embodiment, when waiting to shoot in video recording mode, the rear display unit 101 is hidden, making it difficult for the user to record on the external device 300, and therefore the user can be urged not to record videos on the external device 300 at a frame rate or resolution that the user does not intend.

[Embodiment 4]
Next, with reference to FIG. 3D, a control example will be described in which external output is not performed when the eco mode is on, thereby preventing recording unintended by the user from being performed by the external device 300 .
When the eco mode is on, a video signal is output only to the rear display unit 101 for display, and neither the video signal nor the time code is output to the external device 300 .

Note that, as in embodiment 3, it is also possible to prevent the video signal from being output to the external device 300 only in the video recording mode.

According to this embodiment, when eco mode is on, no video signal is output to the external device 300, so the user can be prompted not to record video with a frame rate or resolution that is not intended by the user on the external device 300.
