Abstract

PROBLEM TO BE SOLVED: To prevent a shutter opportunity from being missed in an electronic camera. SOLUTION: A memory card 24 stores information denoting whether or not the user has selected a mode enabling sound recording control. When a release switch is fully depressed, photographic processing is executed, a photographed is frozen and displayed on an LCD 6, and sound recording processing is started. In the case that information denoting it that the user selects the mode enabling sound recording control is stored in the memory card 24 and the release switch is fully depressed during the sound recording processing, the sound recording is stopped and a new image and a new sound are recorded. Moreover, in the case that the release switch is set at half- depressed state in a similar case, the sound recording processing is stopped and changeover to an electronic view finder mode is made. Furthermore, in the case that the mode disabling sound recording control is set, sound is recorded for only 10 sec regardless of the operation being made, and the processing is finished.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an information processing apparatus, an information processing method, and a recording medium, and more particularly, to an information processing apparatus, an information processing method, and a recording medium capable of recording voice and image.

[0002]

2. Description of the Related Art With the miniaturization of semiconductors and the development of packaging technology, electronic cameras capable of recording not only images of a subject but also audio have come to be marketed.

[0003]

By the way, since an image is spatial information and a sound is temporal information, when recording a sound, a recording start and a recording end are designated. There is a need. For example, when an image and a sound are simultaneously recorded by an electronic camera, the light image of the subject at the time when the release switch is pressed may be recorded in the image. Further specification is required.

Therefore, for example, by starting recording at the same time as photographing is performed, and ending the recording when a predetermined operation is performed, it is possible to simultaneously record the image and the sound. . However, in such a configuration, an operation for terminating the recording must be performed each time shooting is performed, so that there is a problem that the operation is complicated.

In order to solve such a problem, for example, when a release switch is pressed, an optical image of a subject is recorded and recording is performed for a predetermined time (for example, 10 seconds). This eliminates the need to perform an operation to end recording.

[0006] However, in such a configuration, recording is always performed for 10 seconds when photographing is performed. Therefore, for example, even if an unexpected situation necessitates photographing during recording, it is difficult to perform recording. There was also a problem that they could miss the photo opportunity because they could not respond.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and in an electronic camera in which recording is performed at the same time as shooting, it is possible to easily change the timing of ending recording without complicating the operation. Is made possible.

The CPU 39 controls the strobe drive circuit 37 so that the strobe 4 emits light appropriately. In addition, the CPU 39 controls the red-eye reduction lamp drive circuit 38 so that the red-eye reduction lamp is driven before the strobe 4 emits light. 15 is adapted to emit light as appropriate.

When the LCD cover 14 is open (that is, when the electronic viewfinder is used), the CPU 39 does not allow the strobe 4 to emit light. By doing so, the subject can be photographed in the state of the image displayed on the electronic viewfinder.

The CPU 39 records information on the date and time of shooting as header information of the image data in the shot image recording area of the memory card 24 in accordance with the date and time data supplied from the timer 45. (That is, the photographed image data recorded in the photographed image recording area of the memory card 24 is accompanied by data of the photographing date and time).

When the CCD 20 is operating, the image processing unit 31 uses the adjustment values calculated by the CPU 39 using the output of the CCD 20 and used for the white balance control and the control of the luminance value.

Then, the A / D conversion circuit 32 converts the image signal (analog signal) into image data which is a digital signal, and outputs the image data to the DSP 33.

The DSP 33 outputs the image data to the frame memory 35 and causes the LCD 6 to display an image corresponding to the image data.

As described above, in the electronic camera 1, L
When the CD cover 14 is open, at a predetermined time interval,
The CCD 20 operates the electronic shutter.
The electronic viewfinder operation is performed by converting the signal output from 0 into image data, outputting the image data to the frame memory 35, and displaying the image of the subject on the LCD 6 constantly.

As described above, when the LCD cover 14 is closed, the electronic viewfinder operation is not performed, and the operations of the CCD 20, the image processing unit 31, and the aperture driving circuit 53 are stopped, and the power consumption is reduced. Is saving.

Next, shooting of a subject by the present apparatus will be described.

First, the case where the continuous shooting mode changeover switch 13 provided on the surface Y1 is switched to the S mode (a mode in which only one frame is shot) will be described. First, the power switch 11 shown in FIG.
Is switched on, and the power of the electronic camera 1 is turned on. When the subject is confirmed in the viewfinder 2 and the release switch 10 provided on the surface Y1 is pressed, the subject photographing process is started.

When the LCD cover 14 is closed, the CPU 39 restarts the operations of the CCD 20, the image processing section 31, and the aperture driving circuit 53 when the release switch 10 is half-pressed. When the release switch 10 is fully pressed (a state in which the release switch 10 is almost fully operated), the photographing process of the subject is started.

A light image of a subject observed by the finder 2 is condensed by the photographing lens 3 and forms an image on the CCD 20 having a plurality of pixels. The optical image of the subject formed on the CCD 20 is photoelectrically converted into an image signal by each pixel, and is sampled by the image processing unit 31. The image signal sampled by the image processing unit 31 is supplied to an A / D conversion circuit 32, where it is digitized and output to a DSP 33.

When the power of the electronic camera 1 is turned on by switching the power switch 11 to the side where “ON” is printed, and the release switch 10 provided on the surface Y1 is pressed, the subject photographing process is started.

When the LCD cover 14 is closed, the CPU 39 restarts the operations of the CCD 20, the image processing section 31, and the aperture driving circuit 53 when the release switch 10 is half-pressed. When the release switch 10 is fully pressed, the subject photographing process is started.

A light image of a subject observed by the finder 2 is condensed by the photographing lens 3 and forms an image on the CCD 20 having a plurality of pixels. The optical image of the subject formed on the CCD 20 is photoelectrically converted into an image signal at each pixel, and is sampled by the image processing unit 31 at a rate of eight times per second. At this time, the image processing section 31 thins out three-quarters of the pixels of the image electrical signals of all the pixels of the CCD 20.

That is, the image processing section 31 divides the pixels of the CCD 20 arranged in a matrix into regions each having 2 × 2 pixels (four pixels) as shown in FIG. From one area, an image signal of one pixel arranged at a predetermined position is sampled, and the remaining three pixels are thinned.

For example, at the time of the first sampling (first frame), the upper left pixel a of each area is sampled, and the other pixels b, c, and d are thinned out. At the time of the second sampling (second frame), the pixel b at the upper right of each area is sampled, and the other pixels a,
c and d are thinned out. Hereinafter, at the time of the third and fourth samplings, the lower left pixel c and the lower right pixel d
Are sampled and other pixels are decimated. That is, each pixel is sampled every four frames.

The image signal sampled by the image processing section 31 (the image signal of a quarter of all the pixels of the CCD 20) is supplied to the A / D conversion circuit 32, where it is digitized and output to the DSP 33. Is done.

The DSP 33 once outputs the digitized image signal to the buffer memory 36, reads out the image signal, compresses the image signal according to the JPEG system, and converts the digitized and compressed photographed image data into the memory card 24. Is recorded in the captured image recording area. At this time, in the photographed image recording area of the memory card 24, data of the photographed date and time is recorded as header information of the photographed image data.

Third, a continuous shooting mode changeover switch 13
Is switched to the H mode (a mode in which 30 frames are continuously shot in one second). When the power of the electronic camera 1 is turned on by switching the power switch 11 to the side where “ON” is printed, and the release switch 10 provided on the surface Y1 is pressed, the subject photographing process is started.

When the LCD cover 14 is closed and the release switch 10 is half-pressed, the CPU 39 restarts the operations of the CCD 20, the image processing section 31, and the aperture driving circuit 53, When the release switch 10 is fully pressed, the subject photographing process is started.

A light image of a subject observed through the finder 2 is condensed by the photographing lens 3 and forms an image on the CCD 20. An optical image of a subject formed on the CCD 20 having a plurality of pixels is photoelectrically converted into an image signal at each pixel, and is sampled by the image processing unit 31 at a rate of 30 times per second. At this time, the image processing unit 31
8/9 pixels out of the image electrical signals of all the pixels are thinned out.

That is, the image processing section 31 divides the pixels of the CCD 20 arranged in a matrix into regions each having 3 × 3 pixels as shown in FIG. Is sampled at a rate of 30 times per second for the image electric signal of one pixel arranged at the position of
The remaining 8 pixels are thinned out.

For example, at the time of the first sampling (first frame), the upper left pixel a of each area is sampled, and the other pixels b to i are thinned out. At the time of the second sampling (second frame), the pixel b disposed on the right side of the pixel a is sampled, and the other pixels a, c to i are thinned out. Hereinafter, at the time of the third and subsequent samplings, the pixels c, d,.
Are sampled and other pixels are decimated. That is, each pixel is sampled every nine frames.

The image signal sampled by the image processing section 31 (the image signal of one-ninth of all the pixels of the CCD 20) is supplied to the A / D conversion circuit 32, where it is digitized and output to the DSP 33. Is done.

The DSP 33 once outputs the digitized image signal to the buffer memory 36, reads out the image signal, compresses the image signal according to the JPEG method, and converts the digitized and compressed photographed image data into the date and time of photographing. The header information is recorded in the captured image recording area of the memory card 24 along with the header information.

[0095] If necessary, the strobe 4 can be operated to irradiate the subject with light. Where L
When the CD cover 14 is open, that is, when the LCD 6 is performing the electronic viewfinder operation, the CPU 39
Controls the strobe 4 not to emit light.

Next, an operation when two-dimensional information (pen input information) is input from the touch tablet 6A will be described.

When the touch tablet 6A is pressed with the pen tip of the pen 41, the XY coordinates of the touched position are displayed on the CPU.
39 is input. The XY coordinates are stored in the buffer memory 36. In addition, data can be written into the frame memory 35 at locations corresponding to the XY coordinates, and a line drawing corresponding to the contact of the pen 41 can be displayed on the XY coordinates on the LCD 6.

As described above, the touch tablet 6A
Is composed of a transparent member,
The point displayed on the LCD 6 (the point at the position pressed by the pen tip of the pen 41) can be observed, as if the LCD
6 can be felt as if a pen input was made directly. When the pen 41 is moved on the touch tablet 6 </ b> A, a line accompanying the movement of the pen 41 is displayed on the LCD 6. Further, when the pen 41 is intermittently moved on the touch tablet 6A, a broken line accompanying the movement of the pen 41 is displayed on the LCD 6. As described above, the user inputs desired line drawing information such as characters and graphics to the touch tablet 6A (LCD 6).

When the photographed image is displayed on the LCD 6, when line drawing information is inputted by the pen 41, the line drawing information is synthesized with the photographed image information in the frame memory 35, and is simultaneously displayed on the LCD 6. Is displayed.

By operating a color selection switch (not shown), the user can select the color of the line drawing displayed on the LCD 6 from colors such as black, white, red, and blue.

After the line information is input to the touch tablet 6A by the pen 41, when the execution key 7B of the operation key 7 is pressed, the line image information stored in the buffer memory 36 is stored in the memory card 24 together with the header information of the input date and time. And is recorded in the line drawing information recording area of the memory card 24.

The line drawing information recorded on the memory card 24 is information that has been subjected to compression processing. Since the line drawing information input to the touch tablet 6A contains a lot of information having a high spatial frequency component, if the compression processing is performed by the JPEG method used for compressing the photographed image, the compression efficiency is low and the information amount is not reduced. The time required for compression and decompression increases. Furthermore, since the compression by the JPEG method is irreversible compression, it is not suitable for compression of line drawing information having a small amount of information (when expanded and displayed on the LCD 6, gathers and bleeding due to lack of information are noticeable. To get it).

Therefore, in this embodiment, the line drawing information is compressed by the run length method used in facsimile and the like. The run-length method scans a line drawing screen in the horizontal direction, and continues the length of information (points) of each color such as black, white, red, and blue, and the length of continuous non-information (portion without pen input). This is a method for compressing line drawing information by encoding the line drawing information.

By using this run length method,
The line drawing information can be compressed to the minimum, and even when the compressed line drawing information is expanded, it is possible to suppress loss of information. The line drawing information may not be compressed when the information amount is relatively small.

As described above, when a photographed image is displayed on the LCD 6, when a pen input is performed, the photographed image data and the line drawing information of the pen input are combined in the frame memory 35, and the photographed image and the line drawing information are combined. The composite image of LC
Displayed on D6. On the other hand, in the memory card 24, photographed image data is recorded in a photographed image recording area, and line drawing information is recorded in a line drawing information recording area. As described above, since the two pieces of information are recorded in different areas, the user can delete one of the images (for example, the line drawing) from the composite image of the captured image and the line drawing,
Further, each image information can be compressed by an individual compression method.

When data is recorded in the audio recording area, photographed image recording area, or line drawing information recording area of the memory card 24, a predetermined display is displayed on the LCD 6, as shown in FIG.

On the display screen of the LCD 6 shown in FIG. 9, the date when the information was recorded (recorded date) (in this case, August 25, 1995) is displayed at the lower end of the screen. The recording time of the information recorded on the recording date is displayed on the leftmost side of the screen.

A thumbnail image is displayed on the right side of the recording time. This thumbnail image is displayed on the memory card 2
4 is created by thinning (reducing) the bitmap data of each image data of the photographed image data recorded in No. 4. The information with this display is information including captured image information. That is, "10:16" and "10:21"
The information recorded (input) includes the captured image information, such as “10:05”, “10:28”, and “10:28”.
Hour 54 ”and“ 13:10 ”
No image information is included.

A memo symbol “*” indicates that a predetermined memo is recorded as line drawing information.

[0110] On the right side of the thumbnail image display area, an audio information bar is displayed, and a bar (line) having a length corresponding to the length of the recording time is displayed. Do not show).

The user presses any part of the display line of the desired information on the LCD 6 shown in FIG. By pressing with the pen tip of the pen 41, the selected information is reproduced.

For example, when the displayed line of “10:05” shown in FIG.
The CPU 39 reads the audio data corresponding to the selected recording date and time (10:05) from the memory card 24,
After expanding the audio data, the audio data is supplied to the A / D and D / A conversion circuit 42. A / D and D / A conversion circuit 42
Converts the supplied audio data into an analog signal, and then reproduces the data via the speaker 5.

When reproducing the photographed image data recorded on the memory card 24, the user presses the desired thumbnail image with the pen tip of the pen 41 to select the information, and presses the execution key 7B to select the selected information. To play.

The CPU 39 instructs the DSP 33 to read out, from the memory card 24, the photographed image data corresponding to the selected photographing date and time. The DSP 33 expands the photographed image data (compressed photographed image data) read from the memory card 24, stores the photographed image data in the frame memory 35 as bitmap data, and causes the LCD 6 to display it.

The image photographed in the S mode is displayed on the LCD 6 as a still image. This still image is CC
It goes without saying that the image signals of all the pixels of D20 are reproduced.

An image photographed in the L mode is continuously displayed on the LCD 6 at a rate of 8 frames per second. At this time, the number of pixels displayed in each frame is CCD2
0 is a quarter of the total number of pixels.

Normally, the human eye reacts sensitively to the deterioration of the resolution of a still image, and thus thinning out the pixels of the still image is perceived by the user as deterioration of the image quality. However, when the continuous shooting speed at the time of shooting is increased, eight frames are captured per second in the L mode, and when this image is reproduced at a speed of eight frames per second, the number of pixels of each frame becomes equal to the number of pixels of the CCD 20. Although this is a quarter of the number, since the human eye observes eight frames per second, the amount of information perceived by the human eye per second is twice as large as that of a still image.

That is, one of the images shot in the S mode
Assuming that the number of pixels of a frame is 1, the number of pixels of one frame of an image captured in the L mode is １ ／. When an image (still image) captured in the S mode is displayed on the LCD 6, the amount of information perceived by the human eye in one second is 1 (= (number of pixels 1) × (number of frames 1)). On the other hand, when an image captured in the L mode is displayed on the LCD 6, the amount of information perceived by the human eye in one second is 2 (= (number of pixels ４) × (number of frames 8)) (ie, The human eye receives twice as much information as a still image.) Therefore, even if the number of pixels in one frame is reduced to ４, the user can observe the reproduced image at the time of reproduction without much concern about deterioration in image quality.

Further, in this embodiment, since different pixels are sampled for each frame and the sampled pixels are displayed on the LCD 6, an afterimage effect occurs to human eyes, and four minutes per frame. Even if the three pixels are thinned, the user can observe the image photographed in the L mode displayed on the LCD 6 without much concern about the deterioration of the image quality.

An image shot in the H mode is an LC mode.
The images are continuously displayed on D6 at a rate of 30 frames per second. At this time, the number of pixels displayed in each frame is C
Although the number of pixels of the CD 20 is one-ninth of the total number of pixels, for the same reason as in the case of the L mode, the user can copy an image captured in the H mode displayed on the LCD 6 without much concern about deterioration in image quality. Can be observed.

In this embodiment, when the subject is imaged in the L mode and the H mode, the image processing unit 31 thins out the pixels of the CCD 20 to such an extent that the image quality during reproduction is not degraded. The load on the DSP 33 can be reduced, and the DSP 33 can be operated at low speed and low power. In addition, this makes it possible to reduce the cost and power consumption of the device.

By the way, in the present embodiment, it is also possible to record sound simultaneously with shooting. Next, the operation in such a case will be described.

FIG. 10 is a flowchart for explaining an example of the processing for setting the recording mode. This process is executed when the menu key 7A is pressed. In the following processing, the LCD cover 14 will be described for simplicity of explanation.
Is described as being open.

When this processing is executed, in step S1, the CPU 39 determines whether or not “SET UP” (setup) has been selected on the menu screen shown in FIG. Note that this menu screen is a screen displayed on the LCD 6 when the menu key 7A is pressed, and “REC” (recording), “PLAY BACK”
(Play), "SLIDE SHOW" (slide show), and "SET UP" (setup) are displayed as selection items. If it is determined that “SET UP” is not selected (NO), the process returns to step S1, and
The same processing is repeated until “SET UP” is selected. If it is determined that "SET UP" has been selected (YES), the process proceeds to step S2.

In step S2, the CPU 39 reads out predetermined display data from the memory card 24 and writes it into the frame memory 35, thereby causing the LCD 6 to display the setup screen shown in FIG. Then, the process proceeds to step S3. In this display screen, "SHOOTING"
(Shooting), "SPEED LIGHT" (lighting), "IMAGE QUALIT
"Y" (image quality) and "REC CONTROL" (recording control) are displayed.

In the step S3, the CPU 39 executes the processing shown in FIG.
On the setting screen, select the fourth setting item "REC CONT
ROL ”is selected. As a result, the fourth
If it is determined that the fourth setting item has not been selected (NO), the process returns to step S3, and the same processing is repeated until the fourth setting item is selected. If it is determined that the fourth setting item has been selected (YES), the process proceeds to step S4.

In step S4, the CPU 39 reads out predetermined display data from the memory card 24 and writes it into the frame memory 35, thereby causing the LCD 6 to display a recording control setting screen (REC CONTROL) screen shown in FIG. In this display example, "REC CONTROL" indicating that the screen is a recording control setting screen is displayed at the top of the screen, and "ON" and "OFF" are displayed below the screen as setting contents.

In the step S5, the CPU 39 executes the processing shown in FIG.
It is determined whether any one of “ON” and “OFF” has been selected on the setting screen. As a result, if it is determined that neither “ON” or “OFF” has been selected (NO), the process returns to step S5, and the same processing is repeated until the selection is made. If it is determined that either “ON” or “OFF” has been selected (YES), the process proceeds to step S6.

In step S6, the CPU 39 stores the setting contents (ON or OFF) selected in step S5 in the memory card 24, and ends the processing (END).

By the above processing, the recording control is set to "O
It can be set to either "N" or "OFF" state. This recording control will be described later with reference to FIG.

FIG. 14 is a flowchart for explaining an example of the photographing processing executed when the release switch 10 is pressed. When this processing is executed, step S2
At 0, the CPU 39 determines whether or not the release switch 10 has been pressed (fully pressed). As a result, when it is determined that the release switch 10 is not fully pressed (NO), the process returns to step S20, and the same processing is repeated until the release switch 10 is fully pressed. If it is determined that the release switch 10 has been fully pressed (YES), the process proceeds to step S21.

At step S21, a photographing process is executed. That is, the light image of the subject input from the CCD 20, sampled by the image processing unit 31, and further converted to a digital signal by the A / D conversion circuit 32 is an LC image.
D6, and the JPE
After data compression based on the G method is performed, data of the shooting date and time is added and stored in the shot image recording area of the memory card 24.

In the following step S22, a recording process is executed. That is, the sound input to the microphone 8 is converted into a corresponding electric signal and supplied to an A / D and D / A conversion circuit 42, where it is converted into a digital signal and then stored sequentially in the memory card 24. You.

At the next step S23, the CPU 39
The character "REC" is displayed on the LCD 6 to indicate that the recording process has started. FIG.
6 is an example of a photograph of a halftone image displayed in No. 6; In this display example, the photographed image is displayed on the LCD 6. The character "REC" is displayed at the upper left of the screen, indicating that the recording process is being performed.

Returning to FIG. 14, in step S24, C
The PU 10 determines whether 10 seconds have elapsed since the recording process was started (after the release switch 10 was fully pressed). As a result, 10 seconds have elapsed (YE
When it is determined as S), the process proceeds to step S28. Also,
If it is determined that 10 seconds have not elapsed (NO),
Proceed to step S25.

In step S25, the CPU 39 reads the recording control setting information stored in step S6 in FIG. 10 from the memory card 24, and determines whether or not the recording control is ON. As a result, when it is determined that the recording control is not turned on (NO),
Returning to step S24, the same processing as described above is repeated until 10 seconds have elapsed. If it is determined that the recording control is ON (YES), the process proceeds to step S26.

In the step S26, the CPU 39 determines whether or not the release switch 10 is fully pressed. As a result, when it is determined that the release switch 10 is fully pressed (YES), step S is performed.
Proceeding to 31, the CPU 39 ends the recording process and proceeds to step S32. In step S32, the CPU 39
The character "REC STOP" is displayed on the LCD 6 for a predetermined time (for example,
0.5 second). FIG. 16 shows that LC
It is an example of a photograph of a halftone image displayed on D6. In this display example, an image of the photographed subject is displayed on the LCD 6. The character "REC STOP" is displayed at the upper left of the screen, indicating that the recording process has been completed. Then, the process returns to step S21, and the same processing as that described above (photographing processing of a new subject) is performed.

It is desirable to set the display time of “REC STOP” to be short in order to prevent the start of the display processing of a new image from being delayed. For example, the display time is set to be slightly longer. Alternatively, it may be displayed so as to be superimposed on a newly shot image. According to such a method, a new image can be immediately taken regardless of the setting of the display time.

If it is determined in step S26 that the release switch 10 is not fully pressed (NO), the flow advances to step S27.

In step S27, the CPU 39 determines whether or not the release switch 10 has been half-pressed. As a result, if it is determined that the release switch 10 is not half-pressed (NO), the process proceeds to step S2.
4 and the same processing as in the above case is repeated. Also,
The release switch 10 is half-pressed (YE
When it is determined as S), the process proceeds to step S28.

At step S28, CPU 39 ends the recording process and proceeds to step S29. In step S29, the CPU 39 displays “RE” on the screen as shown in FIG.
"C STOP" is displayed for a predetermined time (for example, one second).

In the following step S30, CPU 39
The operation mode is shifted to the electronic viewfinder mode. That is, the CPU 39 controls the CCD 20 at predetermined time intervals.
Is operated as an electronic shutter, the signal output from the CCD 20 is converted into image data, the obtained image data is output to the frame memory 35, and the image of the subject is constantly displayed on the LCD 6, thereby enabling the electronic viewfinder operation. Do. Then, the process ends (END).

Next, the operation of the above-mentioned flowchart will be described in detail using a specific example.

Assuming that the release switch 10 has been pressed (fully pressed), the CPU 39 determines YES in step S20 and proceeds to step S21.

In step S21, a photographing process is executed, and the image of the subject is compressed based on the JPEG standard.
It is recorded on the memory card 24. At this time, LC
At D6, the image of the subject is displayed in a frozen state.

Then, in step S22, the recording process is started, and in the following step S23, "REC" is displayed on the upper left of the LCD 6. As a result, the user can know that the electronic camera 1 is performing the recording process.

In step S24, it is determined whether 10 seconds have elapsed since the start of recording. Now, if 10 seconds have not yet passed since the recording started,
In step S24, NO is determined and step S25
Proceed to.

In step S25, it is determined whether or not the recording control is ON. If it is determined that the recording control is OFF (NO), the process proceeds to step S24.
Return to Therefore, when the recording control is in the OFF state, the recording processing is continued until 10 seconds elapse from the start of the recording processing, and then the recording processing is terminated by the processing from step S28. Is displayed, and the mode shifts to the electronic viewfinder mode. On the other hand, if the recording control is in the ON state, step S2
It is determined YES at 5 and the process proceeds to step S26.

At step S26, the release switch 1
It is determined whether or not 0 is in the fully pressed state. If the release switch 10 is fully pressed by the user during the recording process, YES is determined in step S26, the process proceeds to step S31, and after the recording process is completed, the "REC" is performed in step S32. "STOP" is LCD
6 is displayed. Then, the process proceeds to step S21, where an image of a new subject is photographed.

If it is determined in step S26 that the release switch 10 has not been fully pressed (NO), the flow advances to step S27. In step S27,
It is determined whether or not the release switch 27 has been half-pressed.

If the user has half-pressed the release switch 10, the process proceeds to step S27.
S is determined, the process proceeds to step S28, and the recording process ends. Then, in step S29, "REC ST
After "OP" is displayed on the LCD 6, in step S30, the mode shifts to the electronic viewfinder mode. On the other hand, if the release switch 10 is not half-pressed, the process returns to step S24, and the same processing as in the above-described case is repeated.

According to the above-described processing, if the shooting is performed while the recording control is OFF, the voice recording processing is performed for 10 seconds regardless of the presence / absence of the operation.
The mode shifts to the electronic viewfinder mode. Further, when shooting is performed while the recording control is turned on, a sound recording process is started. And
When the release switch 10 is fully pressed while a voice is being recorded, a new image and voice recording process is performed. On the other hand, if the release switch 10 is half-pressed while the voice is being recorded, the recording process is terminated and the mode shifts to the electronic viewfinder mode. Furthermore, when the recording control is set to the ON state, the photographing is performed, and when no operation is performed during the recording process, the sound is recorded for only 10 seconds, and the mode shifts to the electronic viewfinder mode. Become.
