Description

  The present invention relates to a shooting switching method, an imaging device, and a program that can switch between still image shooting and moving image shooting seamlessly instead of switching modes such as a still image shooting mode and a moving image shooting mode with an imaging device such as a digital camera.

  Cameras with still image shooting and movie shooting functions have traditionally switched between still image shooting mode and movie shooting mode, and then pressed the shutter key or recording start button in each shooting mode to perform still image shooting or movie shooting. However, there is a need to seamlessly shoot still images or moving images at any time immediately by pressing the release button.

  Here, when a still image shooting instruction is issued during movie shooting with an electronic camera equipped with a still image shooting function and a movie shooting function, the still image is temporarily stored in the buffer, and the still image is recorded after the movie is recorded. There is an electronic camera (for example, refer to Patent Document 1).

  Further, as an apparatus for easily switching between a still image shooting mode and a moving image shooting mode, there is an electronic camera (for example, Patent Document 5) that enters a moving image shooting mode when a shutter key is continuously pressed.

  In addition, as a video camera with a still image shooting function and a movie shooting function, when a still image shooting instruction is issued during movie shooting, identification information is added to the image (still image) at the time of the still image shooting instruction in the movie. An electronic camera (for example, refer to Patent Document 2) that controls to sequentially reproduce only still images with still image identification information added during playback of a moving image, or a still image shooting instruction is issued during shooting of a moving image. In some cases, identification information is added to an image (still image) at the time of still image shooting instruction during moving image shooting, and the image is cut out from the moving image and additionally recorded as a new still image (see, for example, Patent Document 3).

  In addition, when a continuous shooting start instruction is issued by pressing the shutter key during continuous shooting of a moving subject, the subject has already started to move and the shooting start timing has deviated. There is an electronic still camera that can capture images retrospectively (see, for example, Patent Document 4).

  FIG. 13 is a schematic explanatory diagram of the photo opportunity retrospective method disclosed in Patent Document 4. According to the photo opportunity retrospective method disclosed in Patent Document 4, the user misses the photo opportunity or erroneously sets the shutter timing. When the user performs a shutter operation when an image 316 as shown in a) (hereinafter, the current through image) is displayed on the screen, when the user switches to the shutter chance retroactive mode, FIG. As shown in b), through images are sequentially displayed at predetermined time intervals from an image 301 (hereinafter referred to as a past through image) that has returned in the past by a predetermined time. When the user performs a shutter operation again with a photo opportunity, an image 310 obtained with a photo opportunity as shown in FIG. 13C can be obtained. In this case, the through image displayed several seconds ago is continuously displayed without stopping the past through image display at the image 316 at the time when the shutter key is pressed. As a result, it is possible to cope with a case where the shutter key is pressed before the photo opportunity.

  FIG. 14 is an explanatory diagram of an embodiment of the layout of the working memory area of a digital camera to which the photo opportunity recurrence method disclosed in Patent Document 4 can be applied, and is a normal shooting mode for capturing an image of one frame size. It is a layout example in the case of. In FIG. 14, areas G1 to G16 secured on the DRAM are storage areas for through-image data captured at predetermined time intervals. An area indicated by reference numeral 1417 is a work area, and an area indicated by reference numeral 1418 is a spare area.

  FIG. 15 is an explanatory diagram of the relationship between the photo opportunity retrospective and the through image in the photo opportunity retrospective method disclosed in Patent Document 4. In FIG. 15, G13 is an area in which image data corresponding to the through image at the time of the shutter operation is stored, and G16 is an area in which image data corresponding to the current through image (that is, at the time of the shutter retroactive operation) is stored. Yes, G1 is an area in which image data corresponding to the most past through image is stored (in this example, through image data 3 seconds before is stored). G10 is an area in which image data of a desired photo opportunity is stored.

  Even if mode switching is not performed in advance, such as still image shooting mode and movie shooting mode, if still image shooting and movie shooting can be performed with a simple key operation in the through image display state, shooting switching can be performed seamlessly until shooting It takes less time and effort. In addition, it can be expected that the chance of taking a still image and the start timing of moving image shooting due to a key operation can be minimized.

  Since the electronic camera described in Patent Document 1 prioritizes moving image shooting, it is easy to shoot a still image during moving image shooting. However, when the still image shooting mode is initially set, switching to moving image shooting is performed first. Has a problem that a time lag for switching occurs and there is a possibility that the start timing of moving image shooting is shifted.

  Also, in the method of reproducing an image shot at the time when a still image shooting instruction is given during moving image shooting as in the electronic camera described in Patent Document 2 above, the shooting condition is optimal for a moving image even if the shooting conditions are optimal for the moving image. However, there is a problem that a still image whose shooting conditions are not appropriate is reproduced.

  In other words, a shooting instruction is given by looking at a through image displayed whether it is still image shooting or moving image shooting. Strictly speaking, a through image and shooting conditions for a still image and a through image and shooting conditions for a movie are determined. For example, since the following (1) to (3) are different, in the method of reproducing a moving image during moving image shooting as a still image like the electronic camera described in Patent Document 2, the shooting condition is the optimum state for the still image. In other words, there is a problem that a still image whose shooting conditions are not appropriate is reproduced.

(1) AF (autofocus);
In still image shooting, AF operation is started by half-pressing the shutter key and shooting is performed by fully pressing, but in moving image shooting, it is followed by continuous AF,
(2) Zoom;
A certain amount of speed is required for still image shooting.
(3) Aperture;
In still image shooting, it stops with a certain amount of aperture, but in moving image shooting, the image size is also smaller than a still image, such as 320 × 240 pixels.

  As in the electronic camera described in Patent Document 3, when a still image shooting instruction is issued during moving image shooting, the image at the time of the still image shooting instruction during moving image shooting is cut out from the moving image and additionally recorded as a new still image. As with the electronic camera described in Patent Document 2, the method has a problem that even if the shooting condition is optimal for a moving image, it is not an optimal state for a still image, and a still image with an inappropriate shooting condition is recorded.

  In the electronic camera disclosed in Patent Document 5, since the moving image shooting mode is set when the shutter key is continuously pressed, the switching from the still image shooting mode to the moving image shooting mode can be performed seamlessly, but the switching is performed while the shutter key is being pressed. For this reason, there is a problem in that there is a possibility that a time lag will occur and the video recording start timing may shift.

In the present embodiment, a shooting switching method and the like for seamlessly switching between still image shooting / moving image shooting by shifting to a shooting (REC) mode that is in a shooting standby state common to still images / moving images immediately after power-on will be described.

  FIG. 1 is a diagram showing the appearance of an embodiment of a digital camera having a still image shooting function and a moving image shooting function. The digital camera 100 has an imaging lens 111 and an optical viewfinder 112 on the front side (FIG. 1A). And a photometric sensor 113. Also, on the back of the digital camera 100 (FIG. 1B), there is a liquid crystal monitor screen 41, an optical viewfinder 112, a mode change switch 31 for switching modes, a liquid crystal monitor switch 32, a menu key 34, a cursor key 35, and a movie shooting. Switches and keys such as a start button 38 and a DISP button 39 for switching display are provided. A zoom lever 33, a shutter key 36, a strobe setting key 37, and a power button 91 are provided on the top surface (FIG. 1C), and external devices such as a personal computer (hereinafter referred to as a personal computer) and a modem are provided on the side. And a USB terminal connection unit 95 used for connecting the USB cable. Furthermore, an optical transmission / reception port for near field communication such as infrared communication or Bluetooth, a radio communication antenna, or a GPS reception antenna may be provided on the front surface or the like.

  FIG. 2 is a block diagram showing an example of the internal configuration of the digital camera shown in FIG. 2, the digital camera 100 includes an optical system 11, a signal conversion unit 12, a signal processing unit 13, a DRAM 14, a control unit 20, an operation unit 30, a display unit 40, a flash memory 50, and a power source 90. The optical system 11, the signal conversion unit 12, and the signal processing unit 13 correspond to an imaging unit that captures a subject image and generates image data.

  The optical system 11 includes an imaging lens 111, a photometric sensor 113, a zoom mechanism 114, an automatic focusing (AF) mechanism 115, an automatic aperture mechanism 116, an automatic exposure mechanism (AE) 117, and the like, and condenses through the imaging lens 111. The luminous flux of the subject image thus formed is formed on a subsequent image sensor (CCD).

  The signal conversion unit 12 includes a signal conversion circuit such as an A / D converter, and also converts an image formed through the preceding optical system 11 into an electric signal by the CCD, and converts the electric signal into digital data. Convert and output at a fixed period.

  In the still image capturing mode, the signal processing unit 13 processes the output from the signal conversion unit 12 to obtain signal components such as digital luminance and color difference multiplexed signals (Y, Cb, Cr data), and Y, Cb , Cr data (hereinafter referred to as image data) is transferred to the DRAM 14 and stored in the still image buffer area of the DRAM 14. Further, in order to display the through image, the image data taken into the DRAM 14 is thinned out and sent to the display unit 40. When the shutter key 36 is fully pressed, the image data at that time is sent to the display unit 40 to display a still image.

  In the moving image capturing mode, the output from the signal conversion unit 12 is processed to obtain signal components such as digital luminance and color difference multiplex signals (Y, Cb, Cr data), and Y, Cb, Cr data (hereinafter referred to as “Y”, “Cb, Cr”) , Image data) is converted to a predetermined moving image file size (for example, about 200 KB / second), transferred to the DRAM 14 as moving image data, and sequentially stored in the moving image buffer area of the DRAM 14. When the confirmation moving image is displayed before recording the moving image (see Modification 3), the moving image data captured in the DRAM 14 is sent to the display unit 40.

  The still image data is stored in the still image buffer area of the DRAM 14 and the moving image data is stored in the moving image buffer area. However, the still image data and the buffer area for storing the moving image data are not separated, and the still image data is stored. You may make it memorize | store in the buffer area | region common to image data and moving image data.

  Further, the signal processing unit 13 reads the image data written in the DRAM 14 at the time of recording and storage, performs compression processing, and applies the compressed image data stored and recorded in the flash memory (storage memory) 50 at the time of reproduction. A compression / decompression unit that performs decompression processing and reproduces image data is provided. Further, a high-speed expansion unit that expands the compressed image data at high speed may be provided. The image data compression / decompression method is, for example, a JPEG compression method, but is not limited thereto.

  The DRAM 14 is used as a working memory, and an image buffer area for temporarily storing captured still images, a moving image buffer area for temporarily storing moving images for a predetermined time, image compression / decompression, and image synthesis A working area for the time is secured. In the embodiment, in the moving image buffer area, for example, when the moving image file size is about 200 KB / second, moving image data for 30 seconds can be stored. In other words, in this case, the maximum time that can be taken in one set (= at a time) is 30 seconds. The time is not limited to 30 seconds.

  The control unit 20 has a microprocessor configuration having a timing mechanism such as a CPU, a RAM, a program storage ROM, and a timer. The CPU is connected to the above-described circuits and a power supply switch (not shown) via a bus line. The entire digital camera 100 is controlled by the control program stored in the program storage ROM, and each mode stored in the program storage ROM corresponding to the status signal from the operation unit 30 is supported. A processing program is taken out and execution control of each function of the digital camera 100 is performed. In addition, by the control based on the operation program at the time of shooting switching, when the main power is turned on, the mode is changed to the shooting mode and a through image is displayed on the shooting standby screen common to still images / moving images as shown in FIG. When the shutter key 36 is half-pressed, optimization of the shooting state such as automatic focusing, automatic aperture, and automatic exposure is started. When the shutter key 36 is fully pressed, still image shooting is performed. When the moving image shooting start button 38 is pressed, optimization of shooting conditions such as continuous automatic focusing, automatic aperture, and automatic exposure by continuous AF is started, and moving image shooting is started.

  The operation unit 30 includes buttons and switches such as a mode switch 31, a liquid crystal monitor switch 32, a zoom key 33, a menu key 34, a cursor key 35, a shutter key 36, a flash setting key 37, a moving image shooting start button 38, and a DISP button 39. When these keys, buttons or switches are operated, status signals and setting values are sent to the control unit 20.

  The display unit 40 is composed of a video encoder, a VRAM (not shown), a liquid crystal monitor screen (LCD) 41, and the like. Through display control of the control unit 20, a through image at the time of imaging, a reproduced image at the time of reproduction, and processing A menu for selection (or icon) at the time of selection is displayed.

  The flash memory 50 records image data (compressed image data). Also, image information including an image shooting mode, shooting date and time, and image identification information can be recorded. Further, a removable storage medium such as a memory card may be used instead of the flash memory 50.

  The photometric sensor 113 measures the amount of light around the digital camera 100 and sends the measured value to the control unit 20. The zoom mechanism 114 changes the focal length to the telephoto or wide-angle side based on the slide operation of the zoom lever 33 by the user. The automatic focusing mechanism 115 moves the lens for focusing by so-called AF (autofocus) under the control of the control unit 20. The automatic diaphragm mechanism 116 performs the diaphragm according to the diaphragm value determined under the control of the control unit 20 based on the peripheral light amount measured by the photometric sensor 113. The automatic exposure mechanism 117 determines the shutter speed according to the exposure value (the light amount taken into the CCD) determined under the control of the control unit 20 based on the peripheral light amount measured by the photometric sensor 113.

  Under the control of the control unit 20, the automatic focusing mechanism 115 starts AF operation by half-pressing the shutter key 36 during still image shooting, and when moving image shooting start button 38 is pressed during moving image shooting, the continuous AF is performed. Start following. Further, as described above, since the aperture value has a value suitable for still image shooting and a value suitable for movie shooting, the control unit 20 determines the aperture value to be suitable for still image shooting in the still image shooting mode. In the movie shooting mode, the aperture value is determined so as to be suitable for movie shooting. Accordingly, the aperture by the automatic aperture mechanism 116 is different between still image shooting and moving image shooting.

  FIG. 3 is an explanatory diagram of an example of a still image / moving image switching method in a shooting standby state. In this embodiment, the digital camera 100 starts from a shooting standby state common to still images / moving images immediately after power-on. Shifts to the shooting (REC) mode (block A). When the user half-presses the shutter key 36 in the shooting mode of the block A and then presses the shutter key 36 halfway, the mode shifts to still image shooting (block B), and when the user presses the moving image shooting start button 38, the moving image shooting (block C) starts. Transition. In addition, it is possible to shift to moving image shooting after the end of still image shooting, or to shift to still image shooting after the end of moving image shooting.

  Further, when the user operates the mode changeover switch 31 in the shooting mode of block A, it is possible to shift to a playback mode (block D), a setting mode such as shooting setting (block F), or the like. Note that transition to various setting modes (block E) in the playback mode can be performed by selecting a displayed menu.

  FIG. 4 is a flowchart showing an operation example of the digital camera 100 at the time of shooting mode switching and at the time of shooting based on the present invention. Steps S1 to S4 and Step S9 are shooting switching of the control unit 20 based on an operation program at the time of shooting switching. It corresponds to the operation by control.

  In FIG. 4, when the main power is turned on, an operation program at the time of shooting switching is started, and the control unit 20 displays a shooting standby screen displaying display information common to still images / moving images as shown in FIG. It displays on the display part 40 (step S1).

  The control unit 20 controls the optical system 11, the signal conversion unit 12, and the signal processing unit 13 to send the image data of the captured subject image to the DRAM 14, temporarily stores it in the still image buffer area, and through the captured image data. The image is thinned out and sent to the display unit 40, and the through image is superimposed on the photographing standby screen (see the standby screen 210 in FIG. 7A) (step S2).

  Further, the control unit 20 checks the status signal from the operation unit 30, and proceeds to step S4 when the user presses the shutter key 36 halfway, and proceeds to step S9 when the user presses the moving image shooting start button 38, and enters the mode. When the changeover switch 31 is operated, the mode is changed to the selected mode (step S3).

  When the shutter key 36 is half-pressed, the control unit 20 controls the optical system mechanisms such as the automatic focusing mechanism 115, the automatic aperture mechanism 116, and the automatic exposure mechanism 117 to optimize the shooting state for still image shooting. Do. That is, the focusing by the automatic focusing mechanism 115, the diaphragm by the automatic diaphragm mechanism 116, the amount of light taken into the CCD by the automatic exposure mechanism 117, the shutter speed, and the like are optimized for still image shooting. During this time, the shutter key 36 is locked (step S4).

  When the optimization of the shooting state is completed, the control unit 20 unlocks the shutter key 36 and checks whether or not the shutter key 36 has been fully pressed. Then, the process proceeds to step S6 (step S5).

  When the shutter key 36 is fully pressed in step S5, the control unit 20 takes out still image data held in the still image buffer area of the DRAM 14 and sends it to the display unit 40 to display a still image (step S6).

  Next, the control unit 20 checks the signal from the operation unit 30 to determine whether or not the mode has been switched to the image recording mode. If the mode has been switched to the image recording mode, the process proceeds to step S8, and if not, the process proceeds to step S14. (Step S7).

  When switched to the image recording mode, the still image data held in the still image buffer area of the DRAM 14 is compressed and recorded in the flash memory 50. At this time, each image is recorded in association with the image information (step S8).

  When the moving image shooting start button 38 is pressed in step S3, the control unit 20 controls the optical system mechanisms such as the automatic focusing mechanism 115, the automatic diaphragm mechanism 116, and the automatic exposure mechanism 117, so that it is continuous. The optimization of the photographing state such as continuous automatic focusing, automatic aperture, and automatic exposure by AF is started (step S9), and the optical system 11, the signal conversion unit 12, and the signal processing unit 13 are controlled at predetermined time intervals. The subject images are continuously thinned out and sent to the DRAM 14 as moving image data, which are sequentially stored in the moving image buffer area. Further, the moving image data is sent to the display unit 40 to display a through image as shown in FIG. 7 (step S10).

  Next, the control unit 20 checks whether or not the longest possible shooting time for one set (30 seconds per set in the embodiment) has elapsed, and if it has elapsed, the process proceeds to step S13 (step S11). If the video recording start button 38 has not been pressed, it is further checked whether or not the video recording start button 38 has been pressed. If the video recording start button 38 has been pressed, the process proceeds to step S13 assuming that a video recording stop instruction has been issued. In this case, the process returns to step S10 (step S12).

  When the longest shootable time per set has elapsed or when the moving image shooting start button 38 is pressed again, a plurality of moving image data held in the moving image buffer area of the DRAM 14 are sequentially compressed and flashed. The data is sequentially recorded in the memory 50 (step S13).

  The control unit 20 clears the still image buffer area and the moving image buffer area of the DRAM 14, and checks the status signal from the operation unit 30, and the user switches to another mode or terminates the operation by operating the mode switch 31 or the like. If it is performed, the shooting mode is terminated, and if not, the process returns to the shooting standby state in step S2 (step S14).

  By the operation based on the explanatory diagram of FIG. 3 and the flowchart of FIG. 4, after the power is turned on, the camera shifts to a shooting standby state without switching to the still image shooting mode or the moving image shooting mode, and the shutter key 36 or the moving image shooting start button 38. You can seamlessly switch between still image shooting and movie shooting with just an operation.

  That is, operability is good because the shooting mode to be taken can be instantly selected. In addition, since the shooting state is optimized according to the shooting mode when shooting is switched, a good image can be obtained. Further, the optimization of the shooting state can be performed without making the user aware of it.

  In step S4, the still image shooting state is automatically optimized. In step S9, the moving image shooting state is automatically optimized. However, in step S1 or step S2, the shooting standby state is performed. Thus, it is possible to manually set shooting conditions such as an aperture value, an exposure value, and a shutter speed, and in step S4 and / or step S9, the shooting state based on the set value may be regarded as the optimum. . In this case, for example, a blurred image can be obtained according to the state of the subject and the surrounding environment.

(Embodiment 2)
In the first embodiment, the shooting standby state after turning on the power is set to the shooting standby state common to still image shooting / moving image shooting, and the through image is superimposed and displayed on the shooting standby screen displaying the display information common to the still image / moving image. When there is an image shooting instruction (full press of the shutter key 36), switching to still image shooting is performed, and when there is a moving image shooting instruction (depressing the moving image shooting start button 38), switching to moving image shooting is performed (see step S1 in FIG. 4). However, as described above, strictly speaking, the display information differs between when still image shooting is performed and when moving image shooting is performed.

  However, in the first embodiment, since the first shooting standby state is common to still images / moving images, it is not known whether still images or moving images are taken. Therefore, it is not known whether display information for still images or moving images may be displayed.

  In the present embodiment, it is possible to specify in advance whether the shooting standby state is for still image shooting or movie shooting (that is, which is prioritized), and the shooting state is an optimum state corresponding to the shooting mode. And In the following description, the digital camera 100 of the first embodiment, that is, the digital camera 100 shown in FIGS. 1 and 2 will be described as an example.

  FIG. 5 is an explanatory diagram of an example of a through image display and still image / moving image switching method in a shooting standby state. In this embodiment, the digital camera 100 immediately enters a shooting (REC) mode after power-on. Transition (block A).

  The block A further includes a shooting standby state (block A-1) for displaying display information common to still images / moving images, and a still image shooting standby state (block A-2) for displaying detailed information for still image shooting. It consists of a moving image shooting standby state (block A-3) that displays simple display information suitable for moving image shooting, and immediately after the power is turned on, it shifts to the shooting standby state of block A-1 and display information common to still images / moving images. Is superimposed on the through image.

  At this time, when the user presses the shutter key 36 halfway, the state shifts to the shooting standby state of the block A-2 and the detailed information on the still image shooting direction is superimposed and displayed on the through image. Further, when the user fully presses the shutter key 36, the process shifts to still image shooting (block B).

  When the user presses the moving image shooting start button 38 in the shooting standby state of the block A-1, the state shifts to the shooting waiting state of the block A-3, and simple information for moving image shooting is superimposed and displayed on the through image. After optimization, the process proceeds to moving image shooting (block C).

  Although not shown, as in FIG. 2, when the user operates the mode changeover switch 31 in the shooting mode of block A, it is possible to shift to a setting mode such as a playback mode or shooting setting. Similarly, transition to various setting modes in the playback mode can be performed by selecting a displayed menu.

  FIG. 6 is a flowchart showing an example of the operation of the digital camera at the time of still image / moving image switching in the shooting standby state and at the time of shooting. Step S3 in the flowchart of FIG. 4 is changed to the following steps S3-1 to S3-3. It has been replaced. That is, the operations up to step S2 and the operations after step S4 (not shown) in the flowchart of FIG. 6 are the same as the operations of the steps in the flowchart shown in FIG.

  In FIG. 6, when the main power is turned on, an operation program at the time of shooting switching is started, and the control unit 20 displays a shooting standby screen displaying display information common to still images / moving images as shown in FIG. It displays on the display part 40 (step S1).

  The control unit 20 controls the optical system 11, the signal conversion unit 12, and the signal processing unit 13 to send the image data of the captured subject image to the DRAM 14, temporarily stores it in the still image buffer area, and through the captured image data. The image is thinned out and sent to the display unit 40, and the through image is superimposed on the photographing standby screen, and the process proceeds to step S3-1 (step S2).

  Next, the control unit 20 examines a signal from the operation unit 30. If the shutter key 36 is half-pressed, the process proceeds to step S3-2. If the moving image shooting start button 38 is half-pressed, the process proceeds to step S3-3. When the mode changeover switch 31 is operated, the mode is changed to the selected mode (step S3-1).

  When the shutter key 36 is pressed halfway in step S3-1, the control unit 20 sends detailed display information for a still image as shown in FIG. 7B to the display unit 40 so as to be superimposed on the through image. (See the shooting standby screen 220 in FIG. 7B), and the process proceeds to the optimization process of the shooting state for still images in step S4 (step S3-2).

  When the moving image shooting start button 38 is pressed in step S3-1, the control unit 20 sends simple display information for moving images as shown in FIG. The image is superimposed (see the shooting standby screen 230 in FIG. 7C), and the process proceeds to step S9 (step S3-3).

By the operation based on the explanatory diagram of FIG. 5 and the flowchart of FIG. 6, after the power is turned on, the camera shifts to a shooting standby state without switching to the still image shooting mode or the movie shooting mode, and further, the shutter key 36 or the movie shooting starts. The user wants to take a still image because only the operation of the button 38 can be seamlessly switched to a shooting standby state displaying display information for still images or a shooting standby state displaying display information for moving images. When you want to take a still image, you can view the display information for the still image, and when you want to take a movie, you can see the display information for the movie. Since the shooting state is optimized for a moving image, a good still image or moving image can be obtained. Further, the optimization of the shooting state can be performed without making the user aware of it.

In this way, the through image 211 is displayed. In addition, the shooting standby screen 210 is common to still images / moving images such as a flash mode 212, a moving image shootable time 216, a still image shootable number 217, a recording memory type 221, a zoom magnification 224, a battery remaining amount display 225, and the like.

The shooting standby screen 230 has simple modes such as a flash mode 212, a shooting mode 215, a moving image shooting time 216, a still image shooting possible number 217, a recording memory type 221, a date / time 223, a battery remaining amount display 225, and the like. Display information is displayed.

<Modification 1>
FIG. 8 is an explanatory diagram of another example of the through image display and still image / moving image shooting switching method in the shooting standby state of the present embodiment. Of the block A in the explanatory diagram of FIG. 1 is changed to the power saving display erase block A-0, and the display information is changed from block A-0 to block A-2 to block A-3 to block A-0 by depressing the DISP button 39. It is.

FIG. 9 is an additional flowchart in the case where the display information is transitioned by pressing the DISP button 39 at the time of still image / moving image switching in the shooting standby state, and between steps S2 and S3 of the flowchart of FIG. As shown in the figure, steps S2-2 to S2-8 for changing display information by depressing the DISP button 39 are added. That is, the operations up to step S2 and the operations after step S3 (not shown) in the flowchart of FIG. 9 are the same as the operations of the steps in the flowchart shown in FIG. In this embodiment, it is assumed that a through image without display information is displayed when a through image is displayed in step S2 of FIG.
9, the control unit 20 checks the type of display information displayed on the display unit 40, and if there is no display information, the control unit 20 proceeds to step S2-3 and details the still image orientation. If it is correct display information, the process proceeds to step S2-5. Otherwise, it is determined that there is simple display information suitable for a moving image, and the process proceeds to step S2-7 (step S2-2).

  If the display information is not displayed in step S2-2, the control unit 20 checks the signal from the operation unit 30. If the DISP button 39 is pressed, the process proceeds to step S2-4 (step S2-3). Then, detailed display information for the still image is sent to the display unit 40 to be superimposed on the through image, and the process proceeds to step S3 (step S2-4).

  When the display information for the still image is displayed in step S2-2, the control unit 20 checks the signal from the operation unit 30, and proceeds to step S2-6 if the DISP button 39 is pressed (step S2-6). In step S2-5, simple display information for moving images is sent to the display unit 40 to be superimposed on the through image, and the process proceeds to step S3 (step S2-6).

  When the display information for the moving image is displayed in step S2-2, the control unit 20 checks the signal from the operation unit 30, and proceeds to step S2-8 if the DISP button 39 is pressed (step S2). -7) The display information is cleared, and the process returns to step S2-2 (step S2-8).

  With the above configuration, every time the DISP button 39 (= display switching key) is pressed, the display information of the imaging standby screen is cyclically displayed as follows: no display information → still image orientation display information → moving image orientation display information → no display information. Can be changed. When the still image orientation display information is displayed, if the shutter key 36 is half-pressed (FIG. 4; step S3), the shooting state for still images is optimized (FIG. 4; step S4). When the moving image shooting start button 38 is pressed while the moving image direction display information is displayed (FIG. 4; step S3), the shooting state for moving images is optimized (FIG. 4; step S9).

  In the examples of FIGS. 8 and 9, when the main power is turned on, a through image without display information is displayed first, but the present invention is not limited to this. For example, display information for a still image may be displayed first, or display information for a moving image may be displayed first. Further, display information common to still images / moving images may be displayed instead of display information. The same applies to the case where shooting / recording of a still image for one frame is completed or when shooting / recording of a set of moving images is finished and the camera returns to a shooting standby state for the next shooting. .

  Further, instead of the DISP button 39, a half-press of the shutter key 36 may be used as a display switching trigger.

<Modification 2>
In the first modification, when the display information for the still image is displayed superimposed on the through image and then the shutter key 36 is pressed halfway, the shooting state for the still image is optimized, and the shutter key 36 is When fully pressed, still image shooting is performed. Further, when the moving image shooting start button 38 is pressed while the display information for moving images is superimposed and displayed on the through image, the shooting state for moving images is optimized, and moving image shooting is started after the optimization.

  However, if there is a display information switching instruction such as the DISP button 39, it is clear whether still image shooting or moving image shooting is performed. Therefore, in this embodiment, as shown in FIG. 10, instead of steps S3 and S9 in the flowchart of FIG. 6, steps S2-9 and S2-9 similar to steps S2-2 to S2-8 in FIG. Step S2-10 replaces the display information for the still image orientation in step S2-4 with the live image superimposed on the through image, and the step after that is step S4 (FIG. 4). The display information for the movie orientation in step S2-6 is obtained. After being displayed superimposed on the through image, the shooting state for moving image shooting is optimized in step S2-9, and further, in the case where a moving image shooting start instruction is given in step S2-10, step S10 in FIG. 4 to proceed to step S10).

  In this embodiment, when the moving image shooting start button 38 is pressed while moving image display information is displayed, the shooting state for moving images is optimized, but the shooting currently optimized by display switching is performed. Since the state is known, instead of depressing the moving image shooting start button 38, the full pressing of the shutter key 36 may be used as a trigger for starting moving image shooting, and the moving image shooting may be stopped when the shutter key 36 is fully pressed again. . In this case, the moving image shooting start button 38 becomes unnecessary. In other words, with this configuration, a display state switching instruction (depressing the DISP button 39 in the embodiment) in the common shooting standby state indicates whether the camera is in a still image shooting standby state or a moving image shooting start standby state, and still image shooting is performed. Since the shooting state for moving images such as AF is optimized in the standby state, still image shooting is performed if the shutter key 36 is fully pressed in the still image shooting standby state, and moving image shooting is performed when the shutter key 36 is pressed in the moving image standby state. Since it can be distinguished even if a still image shooting instruction or a moving image shooting instruction is given by one shooting instruction means such as the start of the moving image, the moving image shooting start button 38 need not be provided.

<Modification 3>
When shooting a still image, the user operates the shutter key 36 while looking at the shooting timing while looking at the viewfinder (through image). However, when shooting a moving subject, the user is distracted by the display information and sets the shutter timing. There is a possibility to miss. Also, even if the shutter key 36 is fully pressed too early, the shooting timing may be missed or shifted. Also, in the case of moving image shooting, there is a case where the timing of starting moving image shooting is missed due to distraction of display information and the like. In the present embodiment, a step is added to a part of the flowchart shown in FIG. 6 to remedy the loss of shooting chance due to missed shooting timing or a shift in shooting instruction (or shooting start instruction).

  FIG. 11 is an explanatory diagram of a still image / moving image retroactive method, FIG. 11 (a) is an explanatory diagram of a still image supplementing method, and FIG. 11 (b) is an explanatory diagram of a moving image retroactive method. 12 is a flowchart in which a still image / moving image retroactive step added to the flowchart of FIG. 4 is added, and FIGS. 12A1 and 12A2 are a flowchart showing additional steps for recording a still image retroactively. (B1) and (b2) are flowcharts showing additional steps for moving image retroactive recording.

[Storing still image data]
The example of FIG. 11A is an application of the retroactive method disclosed in Patent Document 4 described above. In this example, through image data is stored in the still image buffer area of the DRAM 14 at intervals of 0.2 seconds. The image data for 3 seconds (16 sheets) is cyclically stored in 16 divided areas G1 to G16 for one frame of the still image buffer area.

  In the illustrated example, G13 is an area in which image data corresponding to the image captured at the time when the shutter key is fully pressed is stored, and G16 is the newest image data (in this example, 0.6 from when the shutter key 36 is fully pressed). G1 is an area in which image data corresponding to the past image is stored (in this example, the image data three seconds before is stored). Remembered). G10 is an area in which image data of a desired photo opportunity is stored.

  Here, in the still image data, the shutter key 36 is half-pressed in step S3-1 in FIG. 6 and the still image shooting standby state in step S3-2 (that is, the still image orientation display information and the through image are displayed). ) Starts, the image data captured in the regions G1 to G6 at intervals of 0.2 seconds are cyclically stored following the transition of time. Such a still image storing step S3-4 is provided between step 3-2 and step S4 in FIG. 6 as shown in FIG. In this case, the return destination of the control until the shutter key 36 is fully pressed in step S5 is step S2-4.

  With the above configuration, still image data before and after the shutter key 36 is fully pressed can be stored, so that even when the operation of the shutter key 36 is delayed or the operation of the shutter key 36 is too early, a still image of a shutter chance can be stored. it can.

  In the above description, the newest image is the image of the region G16 and the oldest image is the image of the region G1, but the oldest past image region and the current image region are sequentially shifted without being fixed. You may make it go.

[Storing video data]
In the example of FIG. 11 (b), the video recording longest possible time (30 seconds in the embodiment) for one set is the image storage period T ′, and n moving image data for one frame is divided into the divided regions G1 to Gn. It can be stored in time series.
In the example shown in the figure, G1 is an area in which image data corresponding to the most past through image (moving image at the time when a standby state common to still image / moving image shooting) is stored, and G5 starts moving image shooting. This is an area in which image data corresponding to a moving image at the time when the button 38 is pressed is stored. Gm is an area in which the latest image data (in this example, image data corresponding to pressing of the moving image shooting start button 38 again) is stored. However, if the maximum shootable time has elapsed before the moving image shooting start button 38 is pressed again, Gn becomes the newest image data.

  Here, the moving image data includes moving image data obtained by converting the captured image into a moving image until the moving image capturing start button 38 is pressed in step S3-1 after the through image is displayed in step S2 of FIG. Stored sequentially in G1 to G5. Such moving image data storage step S2-11 is provided between step S2 and step S3-1 in FIG. 6 as shown in FIG. 12 (b1).

  With the above configuration, the moving image data before the moving image shooting start button 38 is pressed down can be stored, so that the still image at the shooting start timing can be stored even when the pressing operation of the moving image shooting start button 38 is delayed.

[Retro recording of still images]
In the present embodiment, if the desired shutter chance is confirmed after confirming the image before the still image is recorded, the image before and after the shutter key is fully pressed and stored in the DRAM 14 is displayed on the display unit 40 and the desired shutter chance is stopped. Let the image be a captured image. For this purpose, the following steps S6-2 to S6-4 are added between step S6 and step S7 in FIG. 6 (= step S6 and step S7 in FIG. 4).

  In FIG. 12A2, when a still image is displayed in step S6 in FIG. 6 (= step S6 in FIG. 4), if the displayed still image has a desired photo opportunity, the user presses the shutter key 36. When the finger is released, the process proceeds to step S7 as a photo opportunity OK. On the other hand, when the user feels that the photo opportunity is wrong, if the user releases the shutter key 36 halfway and stops in the half-pressed state, the photo opportunity mode is entered, and the process proceeds to S6-3 (step S6-2). ).

  When the switching to the photo opportunity retrospective mode is performed in step S6-2, the control unit 20 sets the most past still image (G1) that is 3 seconds retroactive from the image at the time of switching to the photo opportunity retrospective mode. Up to new still images are sequentially displayed (step S6-3).

  When the user fully presses the shutter key 36 in the half-pressed state, the process returns to step S6 to display the still image displayed at that time (step S6-4).

  With the above operation, an image can be recorded retroactively to a desired photo opportunity even if the photo opportunity is missed or mistaken in the case of still image shooting.

[Retroactive video recording]
In the present embodiment, in the previous stage of recording a moving image, if the desired moving image shooting start timing is not confirmed after confirming the image, the moving image before the moving image shooting start button pressed down stored in the DRAM 14 is sequentially displayed on the display unit 40 to obtain the desired shooting Make sure to start shooting video from the start timing. For this purpose, the following steps S12-2 to S12-6 are added between step S12 and step S13 in FIG. 4 (= step S12 and step S13 in FIG. 6).

  In FIG. 12B2, when a still image is displayed in step S12 in FIG. 6 (= step S12 in FIG. 4), the user performs a shooting start timing confirmation operation (for example, half-pressing the shutter key 36). The control unit 20 examines the signal from the operation unit 30, and proceeds to step S12-3 if there is a photographing start timing confirmation operation, and proceeds to step S13 if there is no photographing start timing confirmation operation after waiting for a predetermined time (step S13). S12-2).

  The control unit 20 sequentially sends the moving image data (G5 to Gm (or Gn)) stored in the DRAM 14 from the time point when the moving image shooting start button 38 is pressed to the moving image shooting stop operation to be displayed on the display unit 40 (step). S12-3).

  If the shooting start timing of the displayed moving image is a desired shooting start timing, when the user performs a shooting timing confirmation operation (for example, full pressing of the shutter key 36), the flow proceeds to step S13 as shooting start timing OK. On the other hand, when the user feels that the shooting start timing is wrong, when the user releases the shutter key 36 halfway and stops in a half-pressed state, the shooting timing retroactive mode is entered, and S12-5 is entered. (Step S12-4).

  When switching to the shooting start timing retroactive mode is performed in step S12-4, the control unit 20 goes back to the moving image data (G1) at the time of switching to the shooting start timing retroactive mode, and starts moving image shooting start button 38. Up to the moving image data at the time when is pressed is sequentially displayed (step S12-5).

  When the user fully presses the shutter key 36 in the half-pressed state, the moving image data displayed at that time is used as image data at the moving image shooting start timing, and the moving image having the moving image data as the moving image shooting start timing is reconfirmed. The process returns to step S12-5 to confirm with the user (step S12-6).

  With the above operation, moving image data can be recorded retroactively to a desired shooting start timing even if the shooting start timing is missed or mistaken in the case of moving image shooting.
