The buffer memory 11 is a buffer for temporarily storing image data of a subject, which is digitized after being picked up by the CCD 2, and is also used as a working memory of the DSP / CPU 3. The image data temporarily stored in the buffer memory 11 is compressed (encoded) by the DSP / CPU 3 and finally stored in the storage memory 13 as a still image file or a moving image file having a predetermined format (JPEG format or the like). Recorded in. The built-in flash memory 12 stores an operation program of the DSP / CPU 3 and various data used for controlling each unit. The DSP / CPU 3 operates according to the operation program, thereby generating an audio file creating unit, a still image file, and the like. It functions as a creation unit, a moving image file with sound creation unit, a recording control unit, an image playback control unit, a sound playback control unit, and the like.
[0033]
The display device 6 includes a color LCD and a driving circuit thereof, displays a subject image captured by the CCD 2 as a through image when in a shooting standby state, and reads out and expands the stored image from the storage memory 13 when reproducing a recorded image. Display the recorded image. The key input unit 7 includes a plurality of operation keys such as a shutter key, a power key, a MENU key, and a cross key, and outputs a key input signal corresponding to a key operation by a user to the DSP / CPU 3. The clock unit 8 has a calendar function for counting the date and time and a clock function, and sends date data and time data to the DSP / CPU 3 as needed at the time of photographing operation or the like.

The audio processing unit 9 includes a built-in microphone, an amplifier, an A / D converter, a built-in speaker, and the like, converts a sound input to the built-in microphone at the time of shooting in the shooting mode with sound into a digital signal, and sends the digital signal to the DSP / CPU 3. The audio data sent to the DSP / CPU 3 is compressed into an audio file in a predetermined format, and is recorded in the storage memory 13 in association with a plurality of still image files as described later. The recorded audio file is reproduced together with the corresponding still image file, and is output as sound from the built-in speaker.
[0034]
Next, the operation of the electronic still camera 1 having the above configuration according to the present invention will be described. When the still image recording mode with sound is set, the DSP / CPU 3 executes processing according to the flowchart shown in FIG. 2 based on the program. That is, the subject image picked up by the CCD 2 is displayed on the display device 6 as a through image (step S101), and the process waits until the shutter key is pressed (step S102). When the shutter key is pressed, the sound recording is started (step S103), and the sound data detected by the built-in microphone of the sound processing unit 9 and converted into a digital signal is stored in the buffer memory 11.
[0035]
At the same time, the still image photographing process is started (step S104), and the still image data of the subject, which has been captured by the CCD 2 and digitized, is temporarily stored in the buffer memory 11. Next, it is determined whether or not the photographing process of the still image for one screen has been completed (step S105), and if the photographing process has been completed, it is determined whether or not the shutter key is continuously depressed. (Step S106). Then, while the shutter key is being pressed, the loop of steps S104 to S106 is repeated.
[0036]
Therefore, when the shutter key is continuously pressed, the loop of steps S104 to S106 is executed a plurality of times, and a plurality of still image data (continuously shot image data) temporally continuous at the shooting processing interval are stored in the buffer memory 11. Will be temporarily stored. At this time, a continuous shooting interval, which is a time interval from the time when the image data starts to be stored in the buffer memory 11 to the time when the storage is ended and the next image starts to be stored in the buffer memory 11, is also stored in the buffer memory 11. Is done. Of course, when the shutter key is operated instantaneously, only single still image data is stored in the buffer memory 11, and in this case, the continuous shooting interval is not stored.
[0037]
When the user removes his / her finger from the shutter key, the process advances from step S106 to step S107 to determine whether or not continuous shooting is performed, that is, whether or not the image data stored in the buffer memory 11 is for a plurality of images (step S107). ). If the result of this determination is that the image data stored in the buffer memory 11 is for a plurality of images and continuous shooting has been performed, the audio recording is stopped (step S108), and then a plurality of still image files for each image data are stored. And one audio file is created (step S109).
[0038]
That is, as shown in FIG. 3, for each image data, a file name 21, a continuous / single-shot identifier 22, an image number 23, a continuous image number 24, a continuous shooting group number 25, a continuous shooting interval 26, a voice presence / absence flag 27. A still image file 20 composed of image data 28 is created. Here, the file name 21 is a file name of the still image file 20 which is different from each other, and the continuous shooting / single shooting identifier 22 indicates whether the still image file 20 is one in continuous shooting or a single shooting. An identifier (extension). The image number 23 is a continuous number different for each image data 28 regardless of continuous shooting or single shooting, and the continuous shooting image number 24 is a continuous number indicating the number of the image in the continuous shooting group. The continuous shot image number 24 of the first image is “1”. The continuous shooting group number 25 is a number assigned to the continuous shooting group composed of a plurality of still image files 20, and the continuous shooting interval 26 starts when the image data is stored in the buffer memory 11 as described above. This is a time interval from the time when the image is saved to the time when the next image is started to be stored in the buffer memory 11 after the end of the storage. The audio presence / absence flag 27 is a flag indicating whether or not audio data is attached, and the image data 28 is the still image data.
[0039]
The audio file 30 created simultaneously in step S109 includes a file name 31, an audio identifier 32, an audio number 33, and audio data 34, as shown in FIG. Here, the file name 31 is a file name set in the next step S110 described later, and the audio identifier 32 is an identifier (extension) indicating that the file is the audio file 30. The audio number 33 is a continuous number that differs for each audio data 34 regardless of continuous shooting or single shooting, and the audio data 34 is the audio data.
[0040]
Then, in the subsequent step S110, a plurality of still image files 20 and one audio file 30 belonging to the continuous shooting group are recorded in the storage memory 13 in association with each other. That is, in the present embodiment, the file name 21 of the first still image file 20 in the continuous shooting group and the file name 31 of the audio file 30 are the same, and a plurality of still images forming the continuous shooting group are set. By recording the file 20 and the audio file 30 in the storage memory 13, both are recorded in association with each other.
[0041]
On the other hand, if the result of the determination in step S107 is that the image data stored in the buffer memory 11 is a single image and is a single shot, it is determined whether or not 10 seconds have elapsed (step S111). ), Voice recording is continued for 10 seconds after releasing the finger from the shutter key. After 10 seconds have elapsed, the audio recording is stopped (step S112), and one still image file and one audio file are created (step S113).
[0042]
The still image file created in step S113 is slightly different from the still image file 20 shown in FIG. 3, and does not include the continuous shot image number 24, the continuous shot group number 25, and the continuous shot interval 26, and It is composed of only a name 21, a continuous shooting / single shooting identifier 22, an image number 23, a sound presence / absence flag 27, and image data 28. However, the audio file is the same as the audio file 30 shown in FIG. 4 and includes a file name 31, an audio identifier 32, an audio number 33, and audio data 34.
[0043]
Then, in the subsequent step S114, one still image file and one audio file are associated and recorded in the storage memory 13. That is, in the present embodiment, the file name 21 of the still image file and the file name 31 of the audio file 30 are made the same as described above, and one still image file and one audio file are recorded in the storage memory 13. By doing so, both are recorded in association with each other.
[0044]
The method of recording the still image file and the audio file in association with each other is not limited to the above, and the group number or the image number of the related continuous image in the audio file (the first still image in the case of the continuous image, ) May be embedded, or audio data may be embedded in a still image file without creating an audio file.
[0045]
When the reproduction mode is set, the DSP / CPU 3 executes processing according to the flowchart shown in FIG. 5 based on the program. That is, the images are scroll-displayed on the display device 6 in accordance with the operation of the up / down key, for example, in the order of the image number 23, and the images to be displayed are selected in accordance with the selection operation (step S201). Next, whether or not the selected image is a continuous shot image with sound is determined based on the continuous / single-shot identifier 22, the sound presence / absence flag 27, and the like (step S202), and is an image other than the continuous shot image with sound. In this case, according to the selected image, the processing shifts to reproduction processing of a still image with sound, a still image without sound, a moving image with sound, a continuous shot image without sound, and the like.
[0046]
If the selected image is a continuous shot image with sound, the selected still image is played and displayed at the same time as the selected still image, such as "It has sound. Press the right button if you want to play the sound." A message indicating that it is possible is displayed on the display device 6 (step S203). Next, it is determined whether or not voice reproduction has been instructed by the operation of the "right button" (step S204). If there has been no voice reproduction instruction, it is determined whether or not the user has again performed an image selection operation. (Step S205). If the image selection operation has not been performed, the process returns to step S203, and if the image selection operation has been performed again, the process returns to step S201 to execute the process again.
[0047]
Also, as a result of the determination in step S204, when an audio reproduction instruction is given, the continuous shooting group number 25 is the same as the still image selected in step S201, and the continuous shooting image number 24 is “1”. At the same time as searching the still image file 20, the audio file 30 having the same file name as the file name 21 is searched (step S206). As a result, of the plurality of still image files 20 belonging to the same continuous shooting group number 25, the still image file 20 whose continuous shooting image number 24 is “1” and the audio file 30 associated therewith as described above. Is searched.
[0048]
Subsequently, the reproduction and display of the image data 28 in the searched file (the still image file 20 whose continuous image number 24 is “1” among the plurality of still image files 20 belonging to the same continuous image group number 25) is started. At the same time, the reproduction of the audio data 34 in the searched audio file 30 is started (step S207). As a result, the display device 6 displays an image based on the image data in the still image file 20 which is the continuous shooting group to which the selected still image belongs and the continuous shot image number 24 is “1”, and The sound based on the sound data 34 in the associated sound file 30 starts to be emitted from the built-in speaker of the sound processing unit 9.
[0049]
Next, it is determined whether or not the continuous shooting interval 26 in the currently displayed still image file 20 has elapsed (step S208). When the continuous shooting time has elapsed (step S208; YES), the continuous shooting is performed. It is determined whether or not there is a still image file 20 having image data of the next continuous image in the group (step S209). If there is a still image file 20 having image data of the next continuous image, reproduction and display of the image data 28 in the next still image file 20 is started (step S210), and the processing from step S208 is performed. repeat.
[0050]
As a result, images based on the image data 28 in the still image file 20 belonging to the continuous shooting group are sequentially switched and displayed on the display device 6 at the continuous shooting interval, and the associated speaker is built in from the built-in speaker of the audio processing unit 9. The sound based on the sound data 34 in the sound file 30 continues to be emitted.
[0051]
At this time, the image data 28 in the still image file 20 switched and displayed on the display device 6 may have the same image data size as the single-shot image data (an image data size larger than the still image included in the moving image). . Therefore, a high-quality still image is switched and displayed at the continuous shooting time interval on the display device 6, whereby a high-quality pseudo moving image can be displayed, and the still image is displayed. In some cases, the image quality is high. In addition, since the sound based on the sound data 34 in the associated sound file 30 is continuously emitted from the built-in speaker of the sound processing unit 9, a high-quality pseudo moving image is displayed together with the sound, or A still image of high quality can be displayed.
[0052]
When the image display based on the image data 28 in all the still image files 20 belonging to the continuous shooting group is completed (step S209; NO), the process waits until another image selecting operation is performed (step S211), and the image is selected. If an operation has been performed, the process returns and the process from step S201 is executed again.
[0053]
(Second embodiment)
[0054]
6 to 8 show a second embodiment of the present invention, in which a moving image file with sound is also created at the time of continuous shooting. When the still image capturing mode with sound is set, the DSP / CPU 3 executes processing according to the flowchart shown in FIG. 6 based on the program. That is, the subject image picked up by the CCD 2 is displayed as a through image on the display device 6 (step S301), and waits until the shutter key is pressed (step S302). Then, when the shutter key is pressed, the sound recording is started (step S303), and the sound data detected by the built-in microphone of the sound processing unit 9 and converted into a digital signal is stored in the buffer memory 11.
[0055]
At the same time, a still image photographing process is started (step S304), and the still image data of the subject, which is imaged by the CCD 2 and digitized, is temporarily stored in the buffer memory 11. Next, it is determined whether or not the photographing process of the still image for one screen has been completed (step S305). If the photographing process has been completed, it is determined whether or not the shutter key is continuously depressed. (Step S306). Then, while the shutter key is being pressed, the loop of steps S304 to S306 is repeated.
[0056]
Therefore, when the shutter key is continuously pressed, the loop of steps S304 to S306 is executed a plurality of times, and a plurality of temporally continuous still image data is temporarily stored in the buffer memory 11. At this time, a continuous shooting interval, which is a time interval from the time when the image data starts to be stored in the buffer memory 11 to the time when the storage is ended and the next image starts to be stored in the buffer memory 11, is also stored in the buffer memory 11. Is done. Of course, when the shutter key is operated instantaneously, only single still image data is stored in the buffer memory 11, and in this case, the continuous shooting interval is not stored.
[0057]
When the user removes his / her finger from the shutter key, the process advances from step S306 to step S307 to determine whether or not continuous shooting is performed, that is, whether or not the image data stored in the buffer memory 11 is for a plurality of images (step S307). ). If the result of this determination is that the image data stored in the buffer memory 11 is for a plurality of images and is continuous shooting, the audio recording is stopped (step S308), and one still image file is stored for each image data. That is, a plurality of still image files are created (step S309).
[0058]
The still image file created in step S309 is slightly different from the still image file 20 shown in FIG. 3 described above, does not include the continuous shooting interval 26, and has a file name 21, a continuous shooting / single shooting identifier 22, It is composed of an image number 23, a continuous image number 24, a continuous group number 25, a voice presence / absence flag 27 and image data 28.
[0059]
Next, the continuous shot image, that is, the image data of a plurality of images stored in the buffer memory 11, and the audio data, that is, the audio data that is temporarily stored in the buffer memory 11 until the recording is started in step S303 and the recording is stopped in step S308. A moving image file with sound is created by using the file (step S310). As shown in FIG. 7, the moving image file with sound 40 includes a file name 41, a moving image identifier with sound 42, a shooting interval (frame rate) 43, sound data 44, and moving image data 45. Here, the file name 41 is a file name set in the next step S311 described later, and the audio identifier 42 is an identifier (extension) indicating that the file is the moving image file 40 with audio. The shooting interval (frame rate) 43 is a time interval similar to the continuous shooting interval described in the first embodiment, and the audio data 44 starts recording in step S303 and stops recording in step S308. Up to the audio data temporarily stored in the buffer memory 11. The moving image data 45 is composed of a plurality of still image data belonging to the continuous shooting group recorded in a readable manner in the order according to the continuous shooting image number 24.
[0060]
Then, in the subsequent step S311, the plurality of still image files created in step S309 and the moving image file with sound 40 created in step S310 are recorded in the storage memory 13 in association with each other. That is, in the present embodiment, similarly to the above-described embodiment, the file name 21 of the first still image file 20 in the continuous shooting group and the file name 41 of the moving image file with sound 40 are made the same, and By recording a plurality of still image files 20 and a moving image file with sound 40 constituting the continuous shooting group in the storage memory 13, the two are linked and recorded.
[0061]
However, the file name 41 (or other identifiable information) of the moving image file with sound 40 may be embedded in all the still image files 20 constituting the continuous shooting group. In this way, even when any of the plurality of still image files 20 constituting the continuous shooting group is selected at the time of reproduction to be described later, the directly-associated moving image file with sound 40 is searched ( Search).
[0062]
On the other hand, if the result of determination in step S307 is that the image data stored in the buffer memory 11 is for one image and is a single shot, in steps S312 to S315, the above-described steps S111 to S114 in FIG. The same processing as is performed.
[0063]
When the reproduction mode is set, the DSP / CPU 3 executes processing according to the flowchart shown in FIG. 8 based on the program. That is, the images are scroll-displayed on the display device 6 in accordance with the operation of the up / down key, for example, in the order of the image number 23, and the images to be displayed are selected in accordance with the selection operation (step S401). Next, it is determined from the continuous / single-shot identifier 22 and the voice presence / absence flag 27 whether or not the selected image is a continuous-shot image with sound (step S402). Then, the processing shifts to another reproduction processing according to the selected image.
[0064]
If the selected image is a continuous shot image with sound, the selected still image is played and displayed at the same time as the selected still image, such as "It has sound. Press the right button if you want to play the sound." A message indicating that it is possible is displayed on the display device 6 (step S403). Next, it is determined whether or not voice reproduction has been instructed by operating the "right button" (step S404). If there has been no voice reproduction instruction, it is determined whether or not the user has again performed an image selection operation. (Step S405). If the image selection operation has not been performed, the process returns to step S403, and if the image selection operation has been performed again, the process returns to step S401 to execute the process again.
[0065]
Also, as a result of the determination in step S404, when an audio reproduction instruction is given, the continuous shooting group number 25 is the same as the still image selected in step S401, and the continuous shooting image number 24 is “1”. A video file 40 with sound having the same file name 41 as the file name 21 of the still image file 20 is searched (step S406). As a result, the moving image file with sound 40 associated with the selected still image as described above is searched.
[0066]
Subsequently, reproduction of the searched moving image file with sound 40 is started. That is, the moving image data (a plurality of still image data) 45 in the moving image file 40 is sequentially read and displayed on the display device 6, and the sound based on the sound data 44 is reproduced by the built-in speaker of the sound processing unit 9. As a result, a moving image that changes at the shooting interval 43 is displayed on the display device 6 based on the moving image data 45 including the selected still image, and the audio data 44 is output from the built-in speaker of the audio processing unit 9. Based sounds begin to be emitted.
[0067]
Next, it is determined whether or not the reproduction of the reproduced moving image file with sound is completed (step S408), and the reproduction is continued until the reproduction is completed. Thereby, the moving image based on the moving image data 45 that changes at the timing indicated by the shooting interval 43 in the moving image file 40 with sound is displayed on the display device 6, and the sound data 44 is output from the built-in speaker of the sound processing unit 9. Based sounds continue to be emitted.
[0068]
At this time, the still image included in the general moving image has a smaller image data size than the single-shot or continuous-shot image because the shooting speed is prioritized, but each still image of the moving image data 45 of the moving image file 40 with sound is , May have the same image data size as the single-shot image data. Therefore, a high-quality still image is switched and displayed at the shooting interval 43 on the display device 6, whereby a high-quality moving image can be displayed. Even when a still image is displayed, a high-quality still image is displayed. Become. In addition, since the sound based on the sound data 44 in the moving image file 40 with sound continues to be emitted from the built-in speaker of the sound processing unit 9, a high-quality moving image is displayed with sound, or a high-quality still image is displayed. Can be displayed.
[0069]
Each still image of the moving image data 45 in the moving image file with sound 40 recorded in association with the continuous shot image (a plurality of still image files) has a smaller image data size than the single shot or continuous shot image. Is also good. In this case, although the image quality is slightly reduced when the moving image with sound is reproduced, a high-quality pseudo moving image or still image can be displayed using the continuous shot images (a plurality of still image files). Therefore, the object of eliminating the drawbacks of continuous shooting and moving image shooting with sound can be achieved.
[0070]
When the display of the moving image based on the moving image data 45 in the moving image file with sound 40 is completed (step S408; YES), the processing from step S403 is executed again.
[0071]
