Description

  The present invention relates to an imaging apparatus that captures a moving image and a moving image synthesis control program in the imaging apparatus.

  2. Description of the Related Art Conventionally, an electronic camera having a function of synthesizing the left and right side images of each frame constituting a captured moving image has been proposed. When the shutter key is operated, the electronic camera starts measuring the moving image capturing time and executes the first moving image capturing process. In the first moving image capturing process, the right half partial image data in each frame constituting the captured first moving image is cut out, temporarily stored in the DRAM, and the shutter key operation is stopped. The process ends. When the shutter key is operated again, the second moving image capturing process is executed within the measured first moving image capturing time, and the left half partial image data in each frame constituting the second moving image. And temporarily stored in DRAM.

When the second moving image capturing process is completed, the right half partial image in each frame of the first moving image obtained by the first moving image capturing and each of the second moving image obtained by the second moving image capturing. The partial images of the left half of the frame are arranged on the right and left of each frame, and are synthesized for each frame to create a synthesized moving image, which is stored in a memory card. Therefore, finally, it is possible to save a composite moving image in which a partial image captured by the first moving image capturing exists in the right half of each frame and a partial image captured by the second moving image capturing exists in the left half. (For example, refer to Patent Document 1).

  The moving image synthesis function of the electronic camera as described above captures the action of a player as a first moving image and combines the action of another player as a second moving image in sports, dance, arts, or the like. This is mainly used when, for example, the actions of both players serving as comparative controls are displayed on the left and right of the screen during reproduction, and the series of actions of each player is compared and examined by viewing this. Therefore, it is desirable for the right and left images in each frame of the moving image that the motion timings of the respective players are matched in order to accurately compare and examine the motions of both players.

  However, in the above-described moving image synthesizing technique in the conventional electronic camera, the first imaging time and the second imaging time are simply made by matching the moving image imaging time, and then both are synthesized. Therefore, the user cannot be involved in the timing of the frame image in each moving image to be synthesized. Therefore, in the synthesized video, the timing in the sequence of movements of the left and right players may not match, and it is not always useful when comparing and examining left and right images in sports, dance, arts, etc. There wasn't.

  The present invention has been made in view of such conventional problems, and an imaging apparatus and a moving image composition capable of performing composition so that the comparison and examination of the operations of the respective images in the synthesized motion image can be performed accurately. An object is to provide a control program.

In order to solve the above problem, in the imaging apparatus according to the first aspect of the present invention, first moving image imaging means for sequentially capturing an image of a predetermined portion in each frame constituting the moving image, and the predetermined portion in the frame A second moving image capturing unit that sequentially captures images of portions different from the above, a display unit that reproduces and displays the moving images captured by the first and second moving image capturing units, and both moving images on the display unit. In response to a predetermined operation in the state of playback display, designation means for designating the frame of the moving image displayed on the display means at the time of the operation as the start frame of the synthesis, and designation of the start by the designation means from frames, and combining means for combining video until the last frame of one of videos of the both video for each frame, the synthesis of the combining means And a video recording means for recording more resultant synthesized moving.

  Accordingly, since the moving image captured by the first moving image capturing unit and the image captured by the second moving image capturing unit are combined from the frame specified by the specifying unit, each captured and combined The user can be involved in the start timing of the frame image in the moving image. Therefore, the user's involvement in this start timing makes it possible to match the operation timings of the predetermined portion image and the different portion image in each frame of the synthesized moving image.

  Moreover, in the imaging device according to the invention of claim 2, the first moving image capturing unit captures an image of one of the left and right sides of each frame, and the second moving image capturing unit includes: An image of the other side is taken. Therefore, the user's involvement in the start timing makes it possible to match the operation timings of the left and right image portions in each frame of the synthesized moving image.

Further, in the moving image composition control program according to the invention of claim 3, each of the computers constituting the moving image by controlling the moving image capturing means with a computer included in the imaging device including the moving image capturing means and the moving image recording means. First imaging control means for sequentially capturing images of a predetermined portion in the frame, second imaging control means for sequentially capturing images of a portion different from the predetermined portion in the frame, and the first and second imaging Display means for displaying and displaying moving images captured under the control of the control means, and displaying on the display means at the time of the operation in response to a predetermined operation in a state where both moving images are reproduced and displayed on the display means designating means for designating video frame being as a start frame of the synthesis, from the specified frame by the designating means, have the both video Synthesizing means for synthesizing Re or videos to a final frame of one of the video frame by frame, to function synthetic video obtained by synthesizing the combining means as a recording control means for recording the video recording means. Therefore, when the computer executes processing according to this program, the same effects as those of the first aspect of the invention can be obtained.

In the moving image composition control program according to the invention described in claim 4 , the first moving image capturing means captures an image of one of the left and right sides of each frame, and the second moving image capturing means. Is characterized by taking an image of the other side portion . Therefore, when the computer executes processing according to this program, the same effects as those of the invention of claim 2 are obtained.

As described above, according to the inventions according to claims 1 and 3 , since the first captured moving image and the second captured image are synthesized from the designated frame, the captured image is captured. Thus, the user can be involved in the start timing of the frame image in each moving image synthesized. Therefore, due to the user's involvement in this start timing, it is possible to achieve consistency in the operation timing between the image of the predetermined portion and the image of the portion different from the predetermined portion in each frame of the synthesized moving image. This makes it possible to match the timing of a series of actions of the player in the synthesized video to be reproduced when comparing and examining the image of the predetermined part and the image of the part different from the predetermined part in sports, dance, arts, etc. Thus, it becomes possible to accurately compare and examine the actions of the players.

Further, according to the second and fourth aspects of the present invention, it is possible to achieve consistency in the operation timing of the images of the left and right portions in each frame of the synthesized moving image due to the user's involvement with the start timing.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
(First embodiment)

  FIG. 1 is a rear perspective view of a digital camera 1 common to each embodiment of the present invention. As shown in the figure, the digital camera 1 is provided with a power key 3 and a shutter key 4 on the upper surface of the camera body 2, an optical finder 5 on the back surface of the camera body 2, a recording (REC) mode and playback. (PLAY) mode switching switch 6, a liquid crystal monitor 7 that functions as an electronic viewfinder while displaying recorded images and various information, a menu (MENU) key 8 for displaying a menu screen, and a displayed menu Operation keys 9 used for selecting items and the like and for confirming operations are provided.

  In the digital camera 1, in addition to the still image capturing mode as a lower mode of the recording mode, a normal moving image capturing mode and a coupling movie mode are prepared, and each imaging mode can be selected by operating the operation keys 9. Yes. Here, as shown in FIGS. 2 (a) and 2 (b), the coupling movie mode divides each frame constituting a moving image into a left frame portion LF and a right frame portion RF to perform moving image capturing, Finally, as shown in FIG. 6C, a mode in which the left frame portion LF and the right frame portion RF are combined into a single frame F and a moving image composed of the combined frames F is created. It is.

  For this reason, the digital camera 1 further includes an L key 31 that is operated when scrolling the left frame portion LF, an R key 32 that is operated when scrolling the right frame portion RF, and a start when combining. An OK key 33 that is operated when determining a frame or an end frame is provided.

  FIG. 3 is a block diagram showing an outline of the electrical configuration of the digital camera 1. The digital camera 1 includes a CCD 11 that is an image sensor disposed behind the optical axis of an imaging lens 10 disposed on the front side (not shown) of the camera body 2. The CCD 11 is scan-driven by a timing generator (TG) 12 and a vertical driver 13 and outputs an image signal for one screen at a constant period.

  The output signal of the CCD 11 is appropriately adjusted for each RGB primary color component in an analog signal state, sampled and held by a sample hold circuit (S / H) 14, and converted into digital data by an A / D converter 15. It is sent to the color process circuit 16. The color process circuit 16 generates digital luminance signals Y and color difference signals Cb and Cr by color process processing including image interpolation processing, and outputs them to a DMA (Direct Memory Access) DMA controller 17.

  The DMA controller 17 once writes the luminance signal Y and the color difference signals Cb and Cr into the buffer in the DMA controller 17 using the composite synchronization signal, the memory write enable signal, and the clock signal from the color process circuit 16, and the DRAM interface (I / F) DMA transfer to DRAM 19 via 18. After the DMA transfer of the luminance and color difference signal data, that is, the image data to the DRAM 19, the control unit 20 reads the image data from the DRAM 19 via the DRAM interface 18 and writes the image data to the VRAM 22 via the VRAM controller 21.

  The digital video encoder 23 periodically reads out the image data from the VRAM 22 via the VRAM controller 21, generates a video signal based on these data, and outputs the video signal to the display unit 24. The display unit 24 is a display means of the present invention, and is constituted by the liquid crystal monitor 7 and its driving circuit. The display unit 24 performs display based on the video signal from the digital video encoder 23, and is taken in from the VRAM controller 21 at that time. A through image based on the image information is displayed.

  The key input unit 25 includes keys such as the shutter key 4 and the mode change switch 6 described above, and generates a trigger signal for starting imaging when the shutter key 4 is operated in a state where a through image is displayed. .

  In the still image capturing mode in the recording mode, the control unit 20 stops the path from the CCD 11 to the DRAM 19 in response to the trigger signal, and the image data for one frame written in the DRAM 19 is transmitted via the DRAM interface 18. Read out and sent to the JPEG circuit 26. The JPEG circuit 26 compresses and encodes the sent image data, and the compressed image data is read out by the control unit 20 and recorded as a still image file in a flash memory 27 which is a nonvolatile memory. In the moving image capturing mode and the coupling movie mode in the recording mode, reading of the image data from the DRAM 19 and compression encoding of the image data are continuously performed, and the compressed image data for a plurality of frames is stored in a moving image file. Is recorded in the flash memory 27. The moving image composition in the coupled movie mode is performed using the DRAM 19, and the compressed image data for a plurality of frames after the moving image composition is recorded in the flash memory 27 as a moving image file.

  An image (still image, moving image, or synthesized moving image (coupling movie)) file recorded in the flash memory 27 is read into the JPEG circuit 26 in response to a selection operation by the operation key 9 or the like in the reproduction mode, and image data is stored there. Is then sent to the VRAM 22 via the VRAM controller 21 and displayed on the display unit 24.

  The control unit 20 is a microcomputer mainly composed of a CPU and its peripheral circuits, a RAM as a working memory of the CPU, and a built-in clock having a calendar function, and a program area secured in the flash memory 27. It controls based on the program stored in the above, and controls the operation of each unit described above.

  FIG. 4 is a schematic diagram showing a memory area of the DRAM 19 in the coupling movie mode. In the coupling movie mode, a part of the DRAM 19 includes a work area 191, a left partial moving image storage area 192 for storing left partial moving image data including a plurality of frames including only the left frame portion LF, and a right frame portion RF. And a right partial moving image storage area 193 for storing right partial moving image data composed of only a plurality of frames.

  FIG. 5 is a flowchart showing the contents of the coupling movie mode processing by the control unit 20 when the user selects “coupling movie mode” from the menu screen displayed on the liquid crystal monitor 7.

  As the “coupling movie mode” is selected, the control unit 20 masks the right half and displays a through image (step S101). In other words, only the left half image signal is captured from the image pickup signal for one screen output from the CCD 11 on which the subject image is formed by the imaging lens 10, or only the left half image signal is output from the CCD 11. By controlling, the liquid crystal monitor 7 is driven based only on the left half image signal. Therefore, by the processing in step S101, as shown in FIG. 6A, the left partial image L of the through image is displayed in the left region 7L of the liquid crystal monitor 7, and the right region 7R is displayed in black. Note that a through image may be displayed in both the left region 7L and the right region 7R of the liquid crystal monitor 7, and which region is the imaging target region may be displayed. For example, a method of displaying a through image displayed in the right region 7R, which is a non-photographing target region, in monochrome display (low gradation display) or notifying which region is the photographing target region by character display or graphic display is considered. It is done.

  Next, the process waits until the shutter key 4 is operated (step S102). If the shutter key 4 is operated, the left partial image is subjected to moving image imaging processing (step S103). That is, frames in which an image exists only in the left frame portion LF shown in FIG. 2A are sequentially stored in the left partial moving image storage area 192. Next, it is determined whether or not the second operation of the shutter key 4 has been performed (step S104), and when the operation has been performed, the moving image capturing process for the left partial image is terminated (step S105). Therefore, the moving image imaging process of the left partial image is continuously performed within the first and second shutter key 4 operation times. As a result, the left partial moving image storage area 192 stores left partial moving image data including a plurality of frames each having a number corresponding to the time between them and having an image only in the left frame portion LF. It becomes.

  Subsequently, the left half is masked and a through image is displayed (step S106). That is, contrary to the above, only the right half image signal is taken in from the imaging signal for one screen output from the CCD 11 on which the subject image is formed by the imaging lens 10, or only the left and right image signals from the CCD 11. Is controlled so that the liquid crystal monitor 7 is driven based only on the right half of the image signal. Therefore, as a result of the processing in step S106, as shown in FIG. 6B, the right partial image R of the through image is displayed in the left region 7L of the liquid crystal monitor 7, and the left region 7L is displayed in black. In this case as well, as described above, a through image may be displayed in both the left region 7L and the right region 7R of the liquid crystal monitor 7, and which region is the imaging target region may be displayed. Further, the left partial moving image data stored in the left partial moving image storage area 192 may be displayed in the left area 7L of the liquid crystal monitor 7.

  Next, the process waits until the third shutter key 4 is operated (step S107). If the third shutter key 4 is operated, the right partial image is subjected to moving image imaging processing (step S108). That is, frames in which an image exists only in the right frame portion RF shown in FIG. 2B are sequentially stored in the right partial moving image storage area 193. Next, it is determined whether or not the fourth operation of the shutter key 4 has been performed (step S109). When the fourth operation has been performed, the moving image capturing process for the right partial image is terminated (step S110). Therefore, the moving image capturing process for the right partial image is continuously performed within the operation time of the third and fourth shutter keys 4. As a result, the right partial moving image storage area 193 stores right partial moving image data consisting of a plurality of frames each having a number corresponding to the time between them and having an image only in the right frame portion RF. It becomes.

  Then, in the composition processing in the next step S111, the left partial moving image data including a plurality of frames in which an image exists only in the left frame portion LF and the right portion including a plurality of frames in which an image exists only in the right frame portion RF. Combine with video data.

  FIG. 7 is a flowchart showing details of the synthesis process. First, the first frame of the left and right partial videos is displayed side by side (step S201). That is, the first frame of the left partial moving image data stored in the left partial moving image storage area 192 and the first frame of the right partial moving image data stored in the right partial moving image storage area 193 are read out, and data of each image portion is read. Based on the above, the display unit 24 is driven, whereby the liquid crystal monitor 7 displays the image portion of each head frame so that the image portions are arranged side by side. By the processing in step S201, as shown in FIG. 8A, the left partial moving image that is the image of the first frame L-1 of the left partial moving image data is displayed in the left region 7L of the liquid crystal monitor 7, and The right partial moving image that is the image of the first frame R-1 of the right partial moving image data is displayed in the right region 7R.

  Next, it is determined whether or not the L key 31 has been operated (step S202). If the L key 31 has been operated, the next left moving image data displayed in the left area 7L of the liquid crystal monitor 7 is displayed. A frame image is displayed (step S203). Further, it is determined whether or not the R key 32 has been operated (step S204). If the R key 32 has been operated, the next frame of the right partial moving image data displayed in the right area 7R of the liquid crystal monitor 7 is displayed. An image is displayed (step S205). Thereafter, it is determined whether or not the OK key 33 has been operated (step S206), and the processing of steps S202 to S206 is repeated until the OK key 33 is operated.

  During this time, the user operates only the R key 32, only the L key 31, or the R key 32 and the L key 31 until an image of a desired frame to be synthesized as a start frame is displayed in the coupling movie. Then, the images of the left and right areas 7L and 7R of the liquid crystal monitor 7 are scroll-displayed. For example, as shown in FIG. 8B, the image of the fifteenth frame L-15 of the left partial moving image data matches the twentieth frame R-20 of the right partial moving image data as the start frame by the user. Assuming that the frame image is to be displayed, the OK key 33 is operated when the image of the frame L-15 and the frame R-20 are displayed in the left and right areas 7L and 7R of the liquid crystal monitor 7.

  Then, the process proceeds from step S206 to step S207, and the displayed frame L-15 and frame R-20 are determined as start frames in the coupling movie (step S207). Then, the synthesis of the coupling movie is started from the determined start frame. That is, the left partial moving image storage area 192 for storing left partial moving image data composed of a plurality of frames of only the left frame portion LF and the right partial moving image data composed of a plurality of frames of only the right frame portion RF are stored. The moving image data from each determined start frame is read out from the right partial moving image storage area 193, and the image portion of the corresponding frame is cut out in the work area 191 and arranged in parallel on the left and right, and sequentially synthesized for each frame.

  However, the number of frames from the start frame determined at this time to the final frame of the left partial moving image data does not necessarily match the number of frames from the determined start frame to the final frame of the right partial moving image data. Therefore, the synthesis is continued until one of the partial moving image data becomes the final frame (step S209), and when either one of the partial moving image data becomes the final frame (step S209; YES), the synthesis is performed. Is finished (step S210). Thereby, in the work area 191 of the DRAM 19, coupling movie data (synthesized moving image data) is generated by synthesizing the left frame portion LF and the right frame portion RF from each determined start frame to one of the final frames. It will be. In the final step S211, a coupling movie file in which a file name is added to the coupling movie data is stored and saved in the flash memory 27.

  Therefore, when the playback (PLAY) mode is set by operating the mode selector switch 6 and this coupled movie file is played back, the left partial video is displayed in the left and right areas 7L and 7R of the liquid crystal monitor 7 at the timing desired by the user. And the entire moving image in which the right partial moving image starts to be reproduced will be displayed. As a result, when comparing left and right images in sports, dance, arts, etc., the start timings of a series of movements of each player of the left and right partial videos are the same, and each player's movements are compared and examined accurately. Is possible.

  In addition, since the coupling movie data is recorded in the flash memory 27 in the form of a general-purpose movie file, the flash memory 27 can be a memory card that can be attached to and detached from the camera body 2 or a movie recorded in the flash memory 27. By providing the camera body 2 with an output terminal such as a USB terminal for outputting a file to the outside, it becomes possible to reproduce the coupled movie data using an external device and compare and examine the actions of each player. .

  In this embodiment, both the start frame of the left partial video and the start frame of the right partial video can be specified, but either the start frame of the left partial video or the start frame of the right partial video can be specified. It may be possible to specify only. Even in this case, the user can be involved in the timing of either one of the partial videos, so that the start timings in the series of actions of each player of the left and right partial videos can be matched.

(Second Embodiment)
FIG. 9 is a flowchart showing details of the composition processing (step S111) in the second embodiment of the present invention so that not only a start frame for starting composition but also an end frame for ending composition can be designated. It is a thing.

  In this flowchart, the processes of steps S301 to S307 are the same as the processes of steps S201 to S207 in the flowchart of FIG. Therefore, when the process of step S307 ends, the start frames of the left and right partial moving images are determined.

  In step S308 following step S307, it is further determined whether or not the L key 31 has been operated (step S308). If the L key 31 has been operated, it is displayed in the left region 7L of the liquid crystal monitor 7. The image of the next frame of the left partial moving image data is displayed (step S309). However, it is determined whether or not the R key 32 has been operated (step S310), but even if the R key 32 is operated, NOP is set (step S311). Therefore, after the start frames of the left and right partial videos are determined, only the operation of the L key 31 is valid and the operation of the R key 32 is ignored. Thereafter, it is determined whether or not the OK key 33 has been operated (step S312), and the processing of steps S308 to S312 is repeated until the OK key 33 is operated.

  During this time, the user operates only the L key 31 until the end frame image, which is the desired final frame of the left partial video to be synthesized in the coupling movie, is displayed, and the left region 7L of the liquid crystal monitor 7 is displayed. Scroll the image. Then, the OK key 33 is operated when an image is displayed in the left region 7L of the liquid crystal monitor 7 in the desired final frame of the left partial moving image. Then, the process proceeds from step S312 to step S313, and a desired frame of the displayed left partial moving image is determined as an end frame in the coupling movie (step S313).

  Thereafter, the synthesis of the coupling movie is started from the start frame determined in step S307. That is, the left partial moving image storage area 192 for storing left partial moving image data composed of a plurality of frames of only the left frame portion LF and the right partial moving image data composed of a plurality of frames of only the right frame portion RF are stored. The moving image data from each determined start frame is read out from the right partial moving image storage area 193, and the image portion of the corresponding frame is cut out in the work area 191 and arranged in parallel on the left and right, and sequentially synthesized for each frame.

  The synthesis is continued until the end frame determined in step S313 is reached (step S315). When the synthesis up to the end frame is completed (step S315; YES), the synthesis is terminated (step S316). . As a result, in the work area 191 of the DRAM 19, coupling movie data obtained by combining the left frame portion LF and the right frame portion RF from the determined start frame to end frame is generated. In the final step S317, a coupling movie file in which a file name is added to the coupling movie data is stored and stored in the flash memory 27.

  Therefore, when the playback (PLAY) mode is set by operating the mode changeover switch 6 and this coupled movie file is played back, the left part of the left and right areas 7L and 7R of the liquid crystal monitor 7 at the start timing desired by the user is displayed. The entire moving image in which the reproduction of the moving image and the right partial moving image is started and the reproduction ends at the end timing is displayed. As a result, when comparing left and right images in sports, dance, arts, etc., the user's intention is reflected not only at the start timing but also at the end timing in the series of movements of each player of the left and right partial videos. Can be accurately compared and examined.

In this embodiment, the L key 31 and the R key 32 are operated to display a desired frame in the left and right areas, then the OK key 33 is operated to determine the start frame, and then the L key. 31 is used to display the desired frame in the left area, and then the OK key 33 is operated to determine the end frame. First, the L key 31 is operated to display the desired frame in the left area. Then, the OK key 33 is operated to determine the start frame of the left region, the L key 31 is operated to display a desired frame in the left region, and the OK key 33 is operated to display the end frame of the left region. Then, the R key 32 may be operated to display a desired frame in the right region, and the OK key 33 may be operated to determine the right region start frame.
In the present embodiment, the end frame of the left partial video is designated, but the end frame of the right partial video may be designated conversely.

(Third embodiment)
FIG. 10 shows the coupling movie mode process performed by the control unit 20 when the user selects “coupling movie mode” from the menu screen displayed on the liquid crystal monitor 7 in the third embodiment of the present invention. It is a flowchart which shows the content.

  As the “coupling movie mode” is selected, the control unit 20 masks the right half and displays a through image (step S401). In other words, only the left half image signal is captured from the image pickup signal for one screen output from the CCD 11 on which the subject image is formed by the imaging lens 10, or only the left half image signal is output from the CCD 11. By controlling, the liquid crystal monitor 7 is driven based only on the left half image signal. Accordingly, by the processing in step S401, as shown in FIG. 6A, the left partial image L of the through image is displayed in the left region 7L of the liquid crystal monitor 7, and the right region 7R is displayed in black.

  Next, the process waits until the shutter key 4 is operated (step S402). If the shutter key 4 is operated, the left partial image is subjected to moving image imaging processing (step S403). That is, frames in which an image exists only in the left frame portion LF shown in FIG. 2A are sequentially stored in the left partial moving image storage area 192. Next, it is determined whether or not the second operation of the shutter key 4 has been performed (step S404), and when the operation has been performed, the moving image capturing process for the left partial image is terminated (step S405). Therefore, the moving image imaging process of the left partial image is continuously performed within the first and second shutter key 4 operation times. As a result, the left partial moving image storage area 192 stores left partial moving image data including a plurality of frames each having a number corresponding to the time between them and having an image only in the left frame portion LF. It becomes.

  Subsequently, the first frame of the left partial moving image data stored in the left partial moving image storage area 192 is read and displayed on the liquid crystal monitor 7 (step S406), and it is determined whether or not the L key 31 has been operated (step S407). ). When the L key 31 is operated, the image of the next frame of the left partial moving image data displayed in the left region 7L of the liquid crystal monitor 7 is displayed (step S408). Thereafter, it is determined whether or not the OK key 33 has been operated (step S409), and the processing of steps S407 to S409 is repeated until the OK key 33 is operated.

  During this time, the user operates only the L key 31 until the image of the start frame that is the desired first frame of the left partial video to be synthesized in the coupling movie is displayed, so that the left region 7L of the liquid crystal monitor 7 is displayed. Scroll the image. Then, the OK key 33 is operated when the image is displayed in the left region 7L of the liquid crystal monitor 7 in the first frame desired of the left partial moving image. Then, the process proceeds from step S409 to step S410, and a desired frame of the displayed left partial moving image is determined as a start frame in the coupling movie (step S410).

  Next, the determined start frame of the left partial moving image is displayed in the left region 7L of the liquid crystal monitor 7, and the through image is displayed in the right region 7R of the liquid crystal monitor 7 (step S411). In other words, the start frame image of the left partial moving image is fixedly displayed in the left region 7L of the liquid crystal monitor 7, and the right region 7R is output from the CCD 11 on which the subject image is formed by the imaging lens 10. The LCD monitor 7 is driven based on only the right half image signal by taking in only the right half image signal from the image pickup signal for the screen or by controlling the CCD 11 to output only the left and right image signals. To do. Therefore, by the processing in step S411, as shown in FIG. 11A, the fixed image PL of the start frame is displayed in the left region 7L of the liquid crystal monitor 7, and the right partial image R of the through image is displayed in the right region. Will be displayed.

  Next, it is determined whether or not the third shutter key 4 has been operated (step S412). During this time, the timing at which the operation of the right partial image R of the through image matches the form of the fixed image PL comes. Wait for. Then, as shown in FIG. 11 (b), when the timing at which the operation of the right partial image R of the through image matches the form of the fixed image PL has arrived, the user operates the shutter key 4 for the third time. If it does, the moving image imaging process of the right partial image is started (step S413). That is, as described above, frames in which an image exists only in the right frame portion RF shown in FIG. 2B are sequentially stored in the right partial moving image storage area 193. Then, in the left and right composition processing in step S414, the left partial moving image data including a plurality of frames in which an image exists only in the left frame portion LF and the right portion including a plurality of frames in which an image exists only in the right frame portion RF. Combine with video data.

  Then, until the left partial moving image data stored in the left partial moving image storage area 192 becomes the final frame, or until the fourth operation of the shutter key 4, the right partial moving image is continuously captured and combined, When one of the states is reached (step S415; YES), the imaging and composition of the right partial video are finished (step S416). As a result, the work area 191 of the DRAM 19 includes a left frame from the start frame to the final frame of the determined left partial video, or from the determined start frame of the left partial video to the time when the fourth shutter key 4 is operated. Coupling movie data (synthesized moving image data) obtained by synthesizing the part LF and the right frame part RF is generated. In the final step S417, a coupling movie file in which a file name is added to the coupling movie data is stored and saved in the flash memory 27.

  Therefore, in the present embodiment, the synthesis is completed simultaneously with the completion of the imaging of the right partial moving image, and the creation of the coupling movie file can be completed quickly. Furthermore, the user can determine the start frame of the right partial image R from the through image while viewing the start frame of the right partial image R that has already been determined and the right partial image R of the through image that is actually operating. The consistency of the start timing of the left and right partial videos can be further increased.

  In the present embodiment, while the left partial moving image is in the still image state of the start frame, the moving image capturing process for the right partial image is performed in response to the third operation of the shutter key 4. In accordance with the second operation of the shutter key 4, the moving image capturing process for the right partial image may be performed while the left partial moving image is reproduced and displayed. In this embodiment, the left partial video is imaged first and the start frame is determined. However, the reverse of this, or which one is imaged first and the start frame is determined is selected. You may be able to do it.

  Furthermore, in each embodiment, the case where the frame is divided into two equal parts to the left and right has been shown. However, the composition is not limited to the left and right, and may be in the vertical or other division form, and the number of divisions is also divided into two. The present invention can be applied to the case where the composition is not limited to the above but is performed by dividing into a larger number. Further, in each embodiment, the present invention is applied to a digital camera. However, the present invention is not limited to this, and the present invention can also be applied to a camera-equipped mobile phone, a camera-equipped personal computer, a video camera, and the like.
