  Reference numeral 300 denotes a strobe switch that can emit a strobe during moving image shooting.

  FIG. 2 is a flowchart showing the moving image shooting process. This process is mainly executed by the system control circuit 50.

  First, when the power is turned on while the mode dial switch 60 is in the moving image mode, the moving image mode is started. The moving image standby is set, and a live image is displayed on the image display unit 28. In this state, when the shutter switch 64 is pressed, moving image shooting is started (step S201).

  The number N of moving image frames is set to N = 0 at the start of shooting (step S202), and is counted up for each frame (N = N + 1) (step S203).

  Next, it is detected whether or not the strobe switch 300 is turned on (step S204). As a result of the determination in step S204, when it is detected that the strobe switch 300 is turned on, exposure change for strobe light emission is started (step S205).

Thereafter, advance is written that the header of the video frame in the exposure change is being exposed changes for the flash (step S206), it changes the exposure continues writing exposure varying Salaf lug for each video frame until the end of (Step S206 → Step S207 → NO in Step S208 → Step S206).

  When the exposure change is completed in step S208, the strobe light is emitted in the next frame after the exposure change is completed, so the strobe light emission flag is written in the header of the frame after the exposure change (that is, the strobe light emission frame and the light emission information). Are associated) (step S209), and the number N of frames of the moving image is counted up (step S210).

  After the flash emission is finished, it is necessary to return to the normal movie exposure as before the flash emission, so the exposure is changed to the normal movie exposure, and the exposure change flag is written in the header of the movie frame during that time (S step 211 → step S212 → NO in step S213 → step S210).

  When the change to the exposure for the normal moving image is completed in step S213, the process returns to normal moving image shooting (proceeds to step S203).

  If the result of determination in step S204 is that it is not detected that the strobe switch 300 has been turned on, it is determined whether or not moving image shooting has ended (step S214). This determination is performed based on whether or not the shutter switch 64 is pressed again during moving image shooting. In this case, when it is detected that the shutter switch 64 is pressed again, it is determined that the moving image shooting is finished. When it is not detected that the shutter switch 64 is pressed again, the moving image shooting is ended. It is determined that it is not.

  If it is determined as a result of the determination in step S214 that the moving image shooting has been completed, the present process is terminated. If it is determined that the moving image shooting has not been completed, the process returns to step S215.

  Here, an example in which a strobe light emission flag or an exposure change flag is written has been described, but either one may be used. Further, although the exposure change flag is written for all the frames whose exposure is being changed, the flag may be written only for the first and last frames whose exposure is being changed.

  Further, although the strobe switch 300 is turned on and the strobe light is emitted in the next frame after the exposure change is completed, the light is emitted, for example, when the AE (automatic exposure) is lower than a predetermined value (that is, dark). It goes without saying that means are conceivable.

  Furthermore, in the above embodiment, the flag is written in the header of each frame, but the flag may be written together in the header of the moving image file itself. In this case, it is assumed that the plurality of frames constituting the moving image file are described so as to be associated with the flag.

  FIG. 3 is a flowchart showing still image extraction processing. This process is mainly executed by the system control circuit 50.

  This process is a process of extracting a still image from the moving image shot in the moving image shooting process of FIG. 2, and the digital camera 100 can set a still image extraction mode. The still image extracted by this processing can be stored in the recording medium 200 or 210, and the extracted still image can be selected and printed. For convenience of explanation, it is assumed that the exposure change before and after the strobe emission in the moving image shooting process in FIG.

  When the still image extraction mode is selected with the mode dial switch 60, the still image extraction mode is started. In the still image extraction mode, it is selected from which moving image a still image is to be extracted, and the still image extraction process starts after selection (step S301).

  Next, the total frame number Nmax of the moving image selected in step S301 is acquired (step S302), and the moving image frame number counter N is reset to 0 (step S303).

  Thereafter, the frame number counter N of the moving image is incremented by 1 (step S304), the header of the first frame is read (step S305), and it is determined whether or not the strobe light emission flag is ON (step S306). If the result of determination in step S306 is that the strobe emission flag is ON, the frame is registered as a still image in the still image list (step S308), and it is determined whether or not the frame number counter N is Nmax (step S308). Step S313).

  As a result of the determination in step S313, if the frame number counter N is Nmax, the header analysis ends, and the thumbnail of the frame registered in the still image list is displayed on the image display unit 28 as a result (step S314). This process is terminated. On the other hand, if it is determined in step S313 that the frame number counter N is not Nmax, the process returns to step S304.

  If the result of determination in step S306 is that the strobe emission flag is OFF, it is determined whether or not the exposure change flag is ON (step S307). If the result of determination in step S307 is that the exposure change flag is OFF, processing proceeds to step S313. On the other hand, if the exposure change flag is ON, it is determined whether the exposure change flag is an exposure change before the flash emission or an exposure change after the flash emission (step S309). If the result of determination in step S309 is that the exposure change flag is exposure change before flash emission, the previous N-1 frame is registered in the still image list (step S311), and the process proceeds to step S313. If the result of the determination in step S309 is that the exposure change flag is an exposure change after flash emission, after the flash emission (step S310), the subsequent N + 1 frames are registered in the still image list (step S312), and the process proceeds to step S313. .

  By selecting the image displayed on the display unit 28 in step S314, the corresponding frame can be directly printed or saved as a still image in a separate file.

  An operation at the time of reproduction of a moving image file recorded by the moving image shooting process of FIG. 2 will be described.

When the moving image file recorded in FIG. 2 is reproduced as it is, since the exposure for strobe light emission or the strobe light emission itself is recorded as it is when the strobe light is emitted, the moving image file is hard to see for the browsing user. Therefore, the system control circuit 50 previously monitors the exposure change flag and flash emission flag during movie playback, when reproducing the corresponding frame reproduces the previous or subsequent frame in cash comparatively. Thereby, it is possible to appreciate a moving image whose exposure is not unnatural. Of course, the stored moving image may be reproduced as it is, and a selection unit capable of selecting whether or not to replace the frame at the time of strobe light emission with the frame before or after it may be provided. In this case, the selection means is constituted by the operation unit 70.

  As described above in detail, according to the present embodiment, when a strobe emits light during moving image shooting, the strobe-emitted frame included in the moving image file is associated with the light emission information (strobe emission flag). In step S209, a frame associated with the light emission information is extracted from the moving image file (YES in step S306 → step S308 → YES in step S313 → step S314). As a result, still image shooting processing during movie shooting can be achieved by simpler processing than before, thereby enabling still image shooting without missing a photo opportunity and movie shooting with continuity. .

  Another object of the present invention is to supply a storage medium storing software program codes for realizing the functions of the above-described embodiments to a system or apparatus, and a computer (or CPU, MPU, etc.) of the system or apparatus. It is also achieved by reading and executing the program code stored in the storage medium.

  In this case, the program code itself read from the storage medium realizes the functions of the above-described embodiments, and the program code and the storage medium storing the program code constitute the present invention. .
