It is used to alleviate the difference in processing speed in, for example, 33.

The microphone 8 inputs audio information (collects audio) and supplies the audio information to the A / D and D / A conversion circuit 42.

The A / D and D / A conversion circuit 42 converts an analog signal corresponding to the sound detected by the microphone 8 into a digital signal, and converts the digital signal into a digital signal.
In addition to outputting to the PU 39, the audio data supplied from the CPU 39 is converted into an analog signal, and the analogized audio signal is output to the speaker 5.

The photometric element 16 measures the light quantity of the object and its surroundings, and outputs the measurement result to the photometric circuit 51.

The CPU 39 refers to a predetermined table to calculate a white balance adjustment value corresponding to the color temperature supplied from the colorimetric circuit 52, and supplies the white balance adjustment value to the image processing unit 31. It has been made like that.

That is, when the LCD cover 14 is closed, the operation of the CCD 20 is stopped because the LCD 6 is not used as an electronic viewfinder. Since the CCD 20 consumes a lot of power, stopping the operation of the CCD 20 in this way can save the power of the battery 21.

When the LCD cover 14 is closed, the CPU 39 operates until the release switch 10 is operated (until the release switch 10 is half-pressed).
The image processing unit 31 is controlled so that the image processing unit 31 does not perform various processes.

Further, the CPU 39 controls the LCD cover 14
Is closed, until the release switch 10 is operated (until the release switch 10 is half-pressed) so that the aperture driving circuit 53 does not perform operations such as changing the aperture diameter of the aperture 54. The circuit 53 is controlled.

The CPU 39 controls the strobe driving circuit 37 so that the strobe 4 emits light appropriately. In addition, the CPU 39 controls the red-eye reduction lamp driving circuit 38 so that the red-eye reducing 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 photography as header information of image data on the memory card 24 in accordance with the date and time data supplied from the timer 45. (That is, the photographed image data recorded on the memory card 24 is accompanied by data of the photographing date and time).

The CPU 39 compresses the digitized audio information, temporarily stores the digitized and compressed audio data in the buffer memory 36, and then records it in a predetermined area of the memory card 24. It has been made like that. At this time, the recording date and time data is recorded on the memory card 24 as header information of audio data.

The CPU 39 controls the lens driving circuit 30 to perform an autofocus operation by moving the photographing lens 3 and also controls the aperture driving circuit 53 to be disposed between the photographing lens 3 and the CCD 20. Diaphragm 54

Pen operated by user (pen-type indicating member)
When a predetermined position of the touch tablet 6A is pressed by 41 (recording unit selection means, playback order setting means, playback time setting means, information selection means, change means, frame selection means), the CPU 39 presses the touch tablet 6A. The XY coordinates of the designated position are read, and the coordinate data (line drawing information described later) is stored in the buffer memory 36. The CPU 39 records the line drawing information accumulated in the buffer memory 36 together with the header information of the line drawing information input date and time on the memory card 24.

Next, various operations of the electronic camera 1 according to the present embodiment will be described. First, the operation of the electronic viewfinder on the LCD 6 of the present apparatus will be described.

When the user half-presses the release switch 10, the DSP 33 determines whether or not the LCD cover 14 is open based on the value of the signal supplied from the CPU 39 corresponding to the state of the LCD switch 25. L
If it is determined that the CD cover 14 is closed, the electronic viewfinder operation is not performed. In this case, DSP33
Stops the processing until the release switch 10 is operated.

When the LCD cover 14 is closed, the electronic viewfinder operation is not performed.
39 stops the operation of the CCD 20, the image processing unit 31, and the aperture driving circuit 53. And the CPU 39
Operates the photometric circuit 51 and the colorimetric circuit 52 instead of stopping the CCD 20, and supplies the measurement results to the image processing unit 31. The image processing unit 31 uses the values of the measurement results when performing white balance control and luminance value control.

When the release switch 10 is operated, the CPU 39 controls the CCD 20 and the aperture driving circuit 5.
3 is performed.

On the other hand, when the LCD cover 14 is open, the CCD 20 performs an electronic shutter operation at predetermined time intervals and for a predetermined exposure time, and photoelectrically converts the light image of the subject condensed by the photographing lens 3. Then, the image signal obtained by the operation is output to the image processing unit 31.

The image processing section 31 performs white balance control and luminance value control, performs predetermined processing on the image signal, and outputs the image signal to the A / D conversion circuit 32. 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.

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, a 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 second operation has been performed), the photographing process of the subject 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 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.

The DSP 33 temporarily outputs the image data to the buffer memory 36, reads the image data from the buffer memory 36, and performs discrete cosine transformation.
JPEG (Jo that combines quantization and Huffman coding)
(int Photographic Experts Group), and the data is recorded on the memory card 24. At this time, data of the shooting date and time is recorded on the memory card 24 as header information of the shot image data.

When the continuous shooting mode changeover switch 13 is switched to the S mode, only one frame is shot, and even if the release switch 10 is continuously pressed, the subsequent shooting is not performed. I can't. When the release switch 10 is continuously pressed, the taken image is displayed on the LCD 6 when the LCD cover 14 is open.

Second, the continuous shooting mode changeover switch 13
Is switched to the L mode (a mode in which 8 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, 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 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, 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 in accordance with the JPEG system, and converts the digitized and compressed photographed image data into the memory card 24. To record. At this time, the memory card 24
Data of the shooting date and time is recorded as header information of the shot 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, 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 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 temporarily outputs the digitized image signal to the buffer memory 36, reads out the image signal, compresses the image signal in accordance with the JPEG system, and converts the digitized and compressed photographed image data into the date and time of photographing. The header information is recorded on the memory card 24 together.

[0093] 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 a photographed image is displayed on the LCD 6, when line drawing information is inputted by the pen 41, the line drawing information is synthesized together with the photographed image information in the frame memory 35 and 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.

When the enter key 7B of the operation key 7 is pressed after the line information is input to the touch tablet 6A by the pen 41, 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 recorded on 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. To get it).

Therefore, in the present embodiment, the line drawing information is compressed by a run length method used in a facsimile or 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, the photographed image data and the line drawing information are recorded on the memory card 24. As described above, since the two pieces of information are separately recorded, the user can delete one of the images (for example, the line drawing) from the composite image of the photographed image and the line drawing, and further, each image information can be deleted. Can be compressed by individual compression methods.

When a playback mode (see FIG. 12) is designated when a photographed image, a memo image, and audio data are recorded on the memory card 24, a predetermined display is displayed on the LCD 6 as shown in FIG. Done.

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.

On the right side of the recording time, a thumbnail image is displayed. 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 icon displayed on the right of the recording time indicates that predetermined memo information is recorded as line drawing information.

A sound icon is displayed on the right side of the thumbnail image display area, indicating that sound information is recorded.

The user presses any part of the desired information display line of the LCD 6 shown in FIG. 9 with the pen tip of the pen 41 to select and designate the information to be reproduced, and presses the execution key 7B shown in FIG. By pressing with the pen tip of the pen 41, the selected information is reproduced.

For example, when the voice icon displayed at “10:05” shown in FIG. 9 is pressed by the pen 41, the CPU 39 causes the selected recording date and time (10:05).
Minute) from the memory card 24, and after expanding the sound data, the A / D and D /
It is supplied to the A conversion circuit 42. The A / D and D / A conversion circuit 42 converts the supplied audio data into an analog signal,
Playback is performed via the speaker 5.

When reproducing the photographed image data recorded on the memory card 24, the user selects the information by pressing the desired thumbnail image with the pen tip of the pen 41, and presses the execution key 7B to select the 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 is sensitive to the degradation of the resolution of a still image, and thus thinning out the pixels of the still image is perceived by the user as degradation 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 is equal to the pixel number 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 the present embodiment, different pixels are sampled for each frame, and the sampled pixels are displayed on the LCD 6, so that an afterimage effect occurs to human eyes, and 4 pixels per frame. Even if three pixels are thinned out, 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 the present embodiment, the L mode and the H mode
When capturing an image of a subject in the mode, the image processing unit 31 controls the CCD 2 so that the image quality does not deteriorate during reproduction.
Since pixels of 0 are thinned out, the load on the DSP 33 can be reduced, and the DSP 33 can be operated at low speed and with low power. This also means that
The cost and power consumption of the device can be reduced.

By the way, the present embodiment has a mode (slide show mode) in which the reproduction order of the recorded information is set in advance and the information is reproduced in accordance with the set order. The mode will be described.

When the LCD cover 14 of the electronic camera 1 is opened and the power switch 11 is turned on, the LCD
6 is displayed as shown in FIG. In this display example, the current date and time (FRI J
AN 3.1997 22:10:32) is displayed. Below this, the current remaining battery level is displayed (100%). Below that, the current remaining memory capacity is displayed (100%). Below that, the number of images that can be taken (65), the time of audio that can be recorded (1013 seconds), and the number of sets that can be recorded when images and audio are recorded simultaneously (39 sets) are shown. Is displayed.

When the "OK" key displayed at the lower right end of the screen is pressed with the pen 41 on this screen, the image currently input from the CCD 20 is displayed on the LCD 6 as shown in FIG. Is done.

On such a display screen, when the menu key 7A at the lower left of the figure is pressed by the pen 41,
The menu screen shown in FIG. 12 is displayed.

In this display example, “recording (recording) mode”, “playback mode”,
A “slide show mode” and a “setup (environment setting) mode” are displayed. By selecting a desired item with the pen 41, the mode can be shifted to a desired mode.

When the third slide show mode is selected by the pen 41, a slide show mode setting screen shown in FIG. 13 is displayed.

On this display screen, the numbers displayed at the left end of the screen indicate the playback order when the slide show is executed. The number displayed on the right side indicates the recording order in which the information was recorded. Further to the right, as in the case described with reference to FIG. 9, a memo icon, a thumbnail image, a sound icon, and
The playback time is displayed.

Also, the “RE” displayed at the bottom of the screen
“PEAT [1] CYCLE” indicates the number of repetitions (reproduction times) of the slide show. In the case of this example, all information is reproduced only once. For example, if "2" is set as the number of times of reproduction, the same reproduction processing is repeated again after all the designated information is reproduced.

The decrement keys 70 and 71 and the increment key 7 displayed at the bottom of the screen
Numerals 2 and 73 are operated when the reproduction order is changed, and the displayed numerical values are decremented (decreased) or incremented (increased). The decrement key 71 and the increment key 72 decrease or increase the numerical value by one, and the decrement key 70 and the increment key 73 decrease or increase the numerical value by five.

The fact that the reproduction order of the first line is highlighted means that reproduction is started from this reproduction information. Further, as shown in FIG. 17, the reproduction order of the reproduction information reproduced last is also highlighted. Note that the start or end position of the reproduction can be arbitrarily set.

FIG. 14 is a diagram showing one mode of storing the recording information shown in FIG. 13 in the memory card 24.
In this example, the image (captured image 1) displayed on the first line in FIG. 13 is first stored in the memory card 24, and then the image displayed on the first line in FIG. Stored voice (voice 1) is stored. Subsequently, sound 2 (the sound on the second line), photographed image 2 (the photographed image on the third line),
Voice 3 (voice on the third row), memo 1 (memo on the fourth row), and captured image 3 (image on the fourth row) are stored.

As described above, the recorded information is sequentially recorded on the memory card 24. In the example of FIG. 14, information is recorded on the memory card 24 in the order in which the recording was performed. However, actually, information is recorded in an empty area of the memory card 24 in any order. FIG. 15A shows recording information for associating information recorded in this way with recording date and time. That is, information recorded simultaneously is treated as the same recording unit, and the information included in each recording unit is indicated by the recording information.

The recording order at the top of FIG. 15A corresponds to the recording order displayed second from the left end in FIG. 13, and indicates the order in which each recording unit was recorded.
Captured image No. Indicates the number of the captured image included in the recording unit (for example, captured image 1 shown in FIG. 14). Note No. Is the memo number (for example, FIG. 14)
Etc.) shown in FIG. Voice No. Similarly, indicates a voice number (for example, voice 1 shown in FIG. 14). Further, the continuous shooting information indicates whether or not the image included in the recording unit is a continuously shot image, and if the image is a continuously shot image, what number the image is. Is shown. Such recording information is recorded in a predetermined area of the memory card 24.

FIG. 15B shows reproduction information composed of information necessary for reproducing each recording unit. This playback information has a playback order and WAIT added when compared to the recording information. The reproduction order corresponds to the reproduction order displayed at the left end of FIG. 13, and indicates the order in which the recording units are reproduced. Also, WAIT
Indicates a wait time (WAIT time) between the end of reproduction of the recording unit and the reproduction of the next information.
This reproduction information is also recorded in a predetermined area of the memory card 24.

FIG. 16 shows an example of processing for creating the reproduction information shown in FIG. 15B based on the recording information shown in FIG.

This processing is executed when the slide show mode is selected on the menu screen shown in FIG.

When this processing is executed, the CPU 39
In step S1, a variable i for counting the number of processes is initialized to 1. Then, the process proceeds to step S2,
The i-th record information is read from the memory card 24.

In the following step S3, CPU 39
Stores the i-th reproduction information in the memory card 24. That is, since a part of the reproduction information overlaps with the reproduction information, the overlapping part is copied to a predetermined area of the memory card 24. Note that, by default, the reproduction order is the recording order, so the recording order is copied as it is to the area for storing the reproduction order.

In step S4, the CPU 39 determines
It is determined whether audio information is included in the i-th recording unit. As a result, if it is determined that the audio information is included in the recording unit (YES), the process proceeds to step S6,
If it is determined that no voice information is included (NO), the process proceeds to step S5.

In step S5, the CPU 39 determines whether or not the recording unit includes a continuously shot image. That is,
In step S4, it is determined that no audio information is included in the i-th recording unit (NO), and therefore, this recording unit includes either a captured image or memo information, or
This means that both pieces of image information are included. Therefore, in step S5, it is determined whether or not this image information has been continuously shot by referring to the continuous shooting information of the recording information (see FIG. 15). As a result, if it is determined that the image information has been continuously shot (YES), the process proceeds to step S8, where WA
The reciprocal of the frame rate (display time per frame) is stored in the IT, and the process proceeds to step S11. If it is determined that the image information is not continuously shot (NO), the default value is set in the WAIT. A certain 2 (seconds) is stored, and the process proceeds to step S11.

On the other hand, if it is determined in step S4 that voice information is included (YES), the flow advances to step S6. In step S6, the CPU 39 determines that the sound N
o. , The header information of the audio information is read, and it is determined whether or not the reproduction time is less than 2 seconds. As a result, when it is determined that the reproduction time of the audio information is less than 2 seconds (YES), the process proceeds to step S9, and the WAIT is set to (2
The value of (second-sound reproduction time) is stored (set so that the total time of the sound reproduction time and the WAIT is 2 seconds), and the process proceeds to step S11. On the other hand, if it is determined that the audio reproduction time is 2 seconds or longer (NO), 0 is substituted for WAIT, and the process proceeds to step S11.

In step S11, the value of WAIT is stored at the end of the reproduction information already stored in the memory card 24. Then, in step S12, the value of the variable i is incremented by 1, and the process proceeds to step S13.

At step S13, it is determined whether or not there is still a recording unit. As a result, when it is determined that there is still a recording unit (YES), the process returns to step S2, and the same processing as that described above is repeated. On the other hand, when it is determined that the recording unit does not exist (NO), the process proceeds to step S14.

In step S 14, extra (or empty) reproduction information is stored in the memory card 24. Then, the process ends (END). The reason for recording empty reproduction information will be described later.

According to the above processing, the same value as the recording order is set as the reproduction order, and the WAIT time is set according to the type of information included in the recording unit. That is, when audio information is included in the recording unit and the reproduction time of the audio information is 2 seconds or more, 0 seconds is set as the WAIT time, and the audio reproduction time is less than 2 seconds. In this case, the shortage time is set as the WAIT time so that the total reproduction time is 2 seconds.

In the display example of FIG. 13, the reproduction information created as described above is displayed on the screen in ascending reproduction order. The reproduction time at the right end of the figure is WAI
This is the reproduction time including the T time. Therefore, in a recording unit composed of only an image (for example, the recording unit at the bottom end in the figure), the reproduction time is 2 seconds set as the WAIT time.

When no audio information is included (the recording unit is composed of only image information) and the image information is not a continuous image, 2 seconds are set as the WAIT time, In the case of a continuous shot image, the playback time of each frame is set as a WAIT time. For example, FIG. 17 shows a display example of two continuous shot images without sound captured at a frame rate of 1 frame / second. In this case, since 1 second (= 1/1) is set as WAIT, "1" is displayed as the reproduction time as shown in FIG. In this display example, “C” displayed on the left side of the thumbnail image indicates that this image is continuously shot.

In the above processing, with regard to audio information, if the audio reproduction time is less than 2 seconds, the shortage is set to WAIT, and if it is 2 seconds or more,
Although the value of WAIT is set to 0, in the case of audio information, the WAIT time may be set to 2 seconds uniformly as in the case of the image.

Next, a process for reproducing information in the slide show mode based on the reproduction information created as described above will be described.

FIG. 18 is a flow chart for explaining an example of processing executed when the execution key 7B at the lower right of the screen is pressed by the pen 41 in the display example of FIG.

When this processing is executed, step S30
, The CPU 39 initializes a variable i to which the number of processes is substituted to 1. Then, the process proceeds to step S31, where the CPU 39 reads out the reproduction information of the i-th reproduction order from the memory card 24.

In step S32, the CPU 39 determines whether or not the captured information is included in the reproduction information whose reproduction order is the i-th. As a result, if it is determined that the captured image is included (YES), the process proceeds to step S33, where the CPU 39 determines whether the image No. See
The DSP 33 is instructed to read the corresponding photographed image data from the memory card 24. The DSP 33 expands the captured image data (compressed captured image data) read from the memory card 24, stores the captured image data as bitmap data in the frame memory 35, and causes the LCD 6 to display it.

On the other hand, if it is determined in step S32 that the reproduced information does not include a photographed image (NO), the processing in step S33 is skipped and step S3 is performed.
Proceed to 4.

In step S34, CPU 39 determines whether or not the memo information is included in the reproduction information having the i-th reproduction order. As a result, when it is determined that the memo information is included in the reproduction information (YES), the process proceeds to step S35, and the CPU 39 proceeds to step S35. , The DSP 33 is instructed to read the corresponding memo data from the memory card 24. Then, the same processing as in the case of the image data described above is executed, and the memo information is reproduced.

On the other hand, if it is determined in step S34 that the memo information is not included in the reproduction information (NO), the processing in step S35 is skipped and step S3 is performed.
Proceed to 6.

In step S36, the CPU 39 determines whether audio information is included in the reproduction unit whose reproduction order is the i-th. As a result, when it is determined that the audio information is included in the reproduction unit (YES), the process proceeds to step S37, and the CPU 39 determines that the audio No. See
The corresponding audio data is read 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
After the supplied audio data is converted to analog, the audio data is reproduced by the speaker 5.

On the other hand, if it is determined in step S36 that no audio information is included in the reproduction information (NO), the processing in step S37 is skipped and step S37 is skipped.
Proceed to 38.

At step S38, a WAIT process is executed. That is, the CPU 39 reads the value of WAIT of the reproduction information, and suspends the process for a corresponding time. For example, when WAIT = 2, a pause is inserted for two seconds after the reproduction of information is completed.

In the following step S39, the variable i is incremented by one, and in step S40, it is determined whether or not there is reproduction information whose reproduction order is the i-th. As a result, if it is determined that there is playback information whose playback order is the i-th (YES), the process returns to step S31, and the same processing as the above-described case is repeated. If it is determined that there is no reproduction information (NO), step S
Go to 41.

In step S41, a variable Repea to which the number of times of reproduction input from “REPEAT [1] CYCLE” displayed at the bottom of FIG. 13 is substituted.
t is decremented by 1, and the process proceeds to step S42.

In step S42, it is determined whether or not the value of the variable Repeat is 0. As a result, the variable Re
If it is determined that the value of “peat” is not 0 (NO), the process returns to step S30, and the same processing as that described above is repeated. Also, the value of Repeat is 0 (YE
When it is determined as S), the process ends (END).

According to the processing described above, the recording units are sequentially reproduced in the order set in the slide show mode. Further, after each recording unit is reproduced, a pause is inserted for a time corresponding to the WAIT, so that the delimitation of each recording unit becomes clear, and a time for viewing an image is secured with information including only an image. It becomes possible.

In the above-described embodiment, the reproduced image is displayed on the LCD 6 and the sound is reproduced by the speaker 5, but it is connected via a video jack and an audio jack (not shown). Alternatively, images and sounds may be reproduced by an external monitor. In this case, when a cable is connected to a video jack (not shown), the display on the LCD 6 may be stopped to prevent the battery from being consumed.

When the number of times of reproduction displayed at the bottom of FIG. 13 is changed to 999 and the increment key 72 is further pressed, E is displayed and the reproduction is repeated indefinitely. Will be.

Further, in the slide show mode, if the cancel key 7D is pressed while the reproduction is being executed, the reproduction processing is interrupted and the screen returns to the screen shown in FIG.

Further, if the LCD cover 14 is closed while the reproduction is being executed in the slide show mode, the mode immediately shifts to the recording mode to enable the recording of images and sounds. You may. According to such a configuration, even during reproduction, information can be recorded immediately, so that an unexpected situation can be prepared.

Further, in the above embodiment, the recorded information is reproduced in the order of recording, but the reproduction order can be changed. The processing in such a case will be described below with reference to FIG.

The process shown in FIG. 19 is a process executed when the slide show mode is selected. When this processing is executed, in step S60, the CPU 39
Determines whether the recording order of the recording unit whose reproduction order is the i-th (the numerical value in the second column from the right in FIG. 13) has been changed. As a result, if it is determined that the recording order of the i-th recording unit has been changed (YES), the process proceeds to step S61. If it is determined that the recording order has not been changed (NO), the process ends (END). ).

For example, in FIG. 20, when the recording order of the first recording unit is pressed by the pen 41, the display color of that portion is inverted to indicate that the unit is designated. Then, the increment key 7 displayed at the bottom of the screen
When 2 is pressed twice with the pen 41, the recording order is changed from 1 to 3 as shown in FIG. When the recording order is changed in this way, the recording unit to be reproduced first (the recording unit having the first reproduction order) is changed to information having the third recording order. When such an input is executed, the CPU 39 determines in step S60 that (Y
ES), and the process proceeds to step S61.

In step S61, the CPU 39 reads from the memory card 24 the record information having the changed values in the record order. Then, the same processing as in the case of FIG. 16 is executed to generate the WAIT information, and the WAIT information is added to the recording information read in step S61. In the subsequent step S62, the memory card 24 is used as the i-th reproduction information. (The i-th reproduction information is updated with this information).

Then, the process proceeds to a step S 63, wherein the CPU 39
Determines whether or not the i-th reproduction information is the information to be reproduced last (reproduction information that is highlighted). As a result, when it is determined that the i-th reproduction information is the information reproduced last (YES), the process proceeds to step S64,
Also, the i-th reproduction information is not the last information (N
If it is determined as O), the process ends (END).

In step S64, empty information is stored in the memory card 24 as the (i + 1) -th reproduction information. Then, the process ends (END).

That is, as shown in FIG. 21, empty reproduction information is displayed at the end of the slide show setting screen in consideration of a case where a reproduction item is added. This empty (the i-th
In the case where the (th) reproduction information is changed and a new item is added, the (i + 1) -th empty reproduction information is added to prepare for the case where further new information is added. .

According to the above processing, the order of information to be reproduced in the slide show mode can be freely set. When the reproduction information is a continuous shot image, the reproduction order can be reversed, and the reproduction can be performed with the time axis reversed.

Since the reproduction information set as described above is recorded on the memory card 24, when the slide show mode is selected again, the information can be reproduced in the previously set order. Further, the order set in this way can be canceled by, for example, pressing the clear key 7D twice consecutively, and the default state can be restored.

Next, a process for changing the reproduction time of the reproduction information will be described.

FIG. 22 is a diagram showing an example of a process for changing the reproduction time. This process is executed when the slide show mode is selected.

When this processing is executed, step S80 is executed.
In, the CPU 39 determines whether or not the reproduction time of the i-th reproduction information has been changed. As a result, if it is determined that the playback time of the i-th playback information has been changed (YES), the process proceeds to step S81. If it is determined that the playback time has not been changed (NO), the process proceeds. To end (end).

Now, for example, in the display screen shown in FIG. 20, 10 seconds which is the reproduction time of the reproduction information of the first line is
It is assumed that, after being pressed and designated by the pen 41, the increment key 72 is pressed twice and the reproduction time is changed to 12 seconds. Then, the CPU 39 determines YES in step S80, and proceeds to step S81.

At the step S81, the CPU 39 sets the i-th
It is determined whether or not the second reproduction information includes audio information. As a result, when it is determined that the i-th reproduction information includes audio information (YES), the process proceeds to step S83, and when it is determined that audio information is not included (NO), the process proceeds to step S82. Proceed to.

At step S82, the CPU 39 determines whether or not the changed reproduction time is smaller than 0. As a result, if it is determined that the reproduction time is smaller than 0 (YES), the process proceeds to step S85, and 0 is set in the variable WAIT.
And terminate the processing (END). If it is determined that the changed playback time is greater than 0 (NO), the process proceeds to step S84, where the value of WAIT is updated based on the input playback time, and the process ends (END).

When the reproduction time is set to 0, the recording unit specified by the reproduction information is not reproduced.

In step S81, the CPU 3
9 indicates that the i-th reproduction information includes audio information (Y
If it is determined to be (ES), the process proceeds to step S83 to determine whether or not the changed reproduction time is 0 second. As a result, if it is determined that the reproduction time is set to 0 seconds (YES), the process proceeds to step S88, the value of WAIT is set to 0, and the process ends (END). If it is determined that the reproduction time is not 0 second (NO), the process proceeds to step S86.

At step S86, CPU 39 determines whether or not the changed reproduction time is shorter than the reproduction time of the audio. As a result, if it is determined that the changed reproduction time is shorter than the reproduction time of the sound (YES), step S
The process proceeds to 87, for example, displaying a warning message such as "cannot be set!" On the LCD 6, and ends the processing (END). If it is determined that the changed reproduction time is longer than the reproduction time of the sound (NO), step S88
Proceed to.

At the step S88, the CPU 39 sets the WA
Update the value of IT. That is, the CPU 39 sets a value obtained by subtracting the audio reproduction time from the input reproduction time as the WAIT value. Then, the process ends (END).

As described above, when the reproduction time of the first line in FIG. 20 has been changed from 10 seconds to 12 seconds, step S8
When the result is 0, the determination is YES, and the process proceeds to step S81.
Since this recording unit includes audio information, step S
At 81, YES is determined and the process proceeds to step S83. Since the changed playback time is not 0, the process proceeds to step S86, and since the changed playback time is longer than the audio playback time (12> 10), NO is determined. Is determined, the process proceeds to step S88, and the value of WAIT is changed. Now, the value of WAIT is set in step S10 in FIG.
Is set to 0 seconds by the processing of the above, the value is updated from 0 seconds to 2 seconds.

According to the above processing, it is possible to set the reproduction time of the information reproduced in the slide show mode. For example, it is possible to freely set the reproduction time according to the type of information. . Further, as described above, by setting the reproduction time to 0 seconds, it is possible to stop reproduction of the information while keeping the reproduction information.

Next, a process for selecting information to be reproduced in the slide show mode will be described. FIG. 23 illustrates an example of a process of selecting information to be reproduced in the slide show mode. This process is executed when the slide show mode is selected.

When this processing is executed, the CPU 39
In step S100, it is determined whether deletion of predetermined information of the i-th reproduction information has been designated.
As a result, if it is determined that the deletion of the predetermined information of the i-th reproduction information has been designated (YES), the process proceeds to step S101, and the deletion has not been designated (N
If it is determined as O), the process ends (END).

For example, if it is assumed that the sound icon of the reproduction information on the first line in FIG. 20 is pressed by the pen 41 and the clear key 7C is pressed subsequently, step S100
Is determined to be YES and the process proceeds to step S101.

In step S101, when the designated information is deleted, it is determined whether or not all information of the i-th reproduction information is to be deleted. As a result, when it is determined that all information is to be deleted (YES), the process proceeds to step S105, and when it is determined that only some information is to be deleted (NO), Proceeds to step S102.

At step S102, CPU 39 determines whether or not deletion of audio information has been designated. As a result, when it is determined that the deletion of the audio information is designated (YES), the process proceeds to step S103, and 2 is substituted into WAIT (after the audio is deleted, only the image is included. The default value 2 is set), and the process proceeds to step S104. If it is determined that the deletion of the voice information has not been designated (NO), step S10
The process skips step 3 and proceeds to step S104.

At step S104, CPU 39 deletes the specified information from the reproduction information. That is, FIG.
Among the reproduction information shown in (B), the information No. of the information corresponding to the specified information. Is deleted, and the process ends (END).

If it is determined in step S101 that all information is to be deleted from the i-th reproduction information (YES), the flow advances to step S105 to delete all the i-th reproduction information. I do. Then, the process proceeds to step S106, where the (i + 1) -th and subsequent pieces of reproduction information are shifted forward one by one, and the process ends (END).

As described above, assuming that the deletion of the audio information on the first line in FIG. 20 is designated, step S10
It is determined as YES at 0, and the process proceeds to step S101. In this case, since the image information remains even when the audio information is deleted, the determination in step S101 is NO, and the process proceeds to step S102. In step S102, since the deletion of the voice information has been specified, YES is determined. In step S103, WAIT is set to 2, and in step S104, FIG.
(B) of the reproduction information shown in FIG. Is deleted. As a result, audio information is deleted from the reproduction information on the first line,
The playback time is set to 2 seconds.

Further, for example, after all information of the reproduction information on the first line is designated by the pen 41, the clear key 7
If C is pressed, YE is determined in step S101.
It is determined to be S, and in step S105, all information of the first reproduction information is deleted. In the following step S106, the reproduction order of the reproduction information of the second and subsequent lines is decremented by one, and the screen display is also scrolled upward by one line.

According to the above processing, in the slide show mode, it is possible to appropriately select and reproduce information included in a recording unit. Further, when the predetermined information is deleted, the information itself is stored since the information itself is deleted from the reproduction information (memory card 24).
Will not be removed from.) Therefore, it is possible to reproduce the deleted information again in the slide show mode.

Next, a process of deleting a predetermined frame (frame) of a continuously shot image continuously shot with sound will be described.

FIG. 24 is a flowchart for explaining an example of a process capable of deleting a predetermined frame of a continuously shot image recorded with sound. That is, if all the reproduction information corresponding to the predetermined frame (and the audio information at the same time) is deleted from the continuous shot images in which the audio is recorded at the same time, the audio is intermittently reproduced during the reproduction. Therefore,
The following processing is configured so that such a situation does not occur.

The process shown in FIG. 24 is executed when the slide show mode is selected. When this processing is executed, the CPU 39 determines in step S120 that the i-th
It is determined whether or not deletion of the predetermined information of the th reproduction information is specified. As a result, when it is determined that the deletion of the predetermined information of the i-th information is specified (YES), the process proceeds to step S121. If it is determined that the deletion has not been designated (NO), the process ends (END).

In step S121, CPU 39 determines whether or not the information designated to be deleted is a continuous shot image including audio information. That is, the CPU 39 outputs the continuous shooting information and the audio No. of the reproduction information shown in FIG. , It is determined whether or not the designated information is a continuous shot image and includes audio information. As a result, the designated information is a continuously shot image and includes audio information (YES).
If it is determined that the image is not a continuous shot image or contains no sound (NO), the process proceeds to step S122.

At step S123, CPU 39 determines whether or not the designated information is the first continuously shot image. As a result, when it is determined that the designated information is the first continuously shot image (YES), step S12 is performed.
Proceeding to 5, the second image is registered as the first image. That is, the CPU 39 sets the image No. of the second reproduction information. Is the image No. of the first reproduction information. Copy to
The process ends (END).

In step S123, the CPU
If it is determined that the designated information is not the first consecutively shot image (NO), the process proceeds to step S126, and the (i-1) th image is registered as the ith image. . That is, the CPU 39 sets the image No. of the i-th reproduction information designated to be deleted. Is the image No. of the (i-1) th reproduction information. Update by Then, the process ends (END).

On the other hand, if it is determined in step S121 that the designated information is not a continuous shot image including audio (NO), the flow advances to step S122. Step S
In 122, when the specified information is deleted, the CPU 39 determines whether or not all information of the i-th reproduction information is to be deleted. As a result, if it is determined that only part of the information will be deleted (NO),
Proceeding to step S128, the designated information is deleted from the reproduction information, and the process ends (end). If it is determined that all information is to be deleted (YES), the process proceeds to step S124.

In step S124, CPU 39 deletes all the i-th reproduction information. And step S
Proceeding to 127, the CPU 39 shifts the (i + 1) -th and subsequent pieces of reproduction information one by one forward. This process is the same as the process of step S106 in FIG.

According to the above-described processing, even when a predetermined frame is deleted from a continuously shot image in which sound is recorded at the same time, the preceding and following images (in the case of the first image, The immediately following image, and the other images, the immediately preceding image) are reproduced instead, and the sound is normally reproduced.

In the above-described processing, when a predetermined frame is deleted from a continuously shot image accompanied by sound, an image of any one of the frames before and after the frame is displayed.
For example, when the continuously shot image includes sound, deletion of the image may be prohibited. Alternatively, when a predetermined frame is deleted, it is possible to reproduce only the sound without reproducing the frame.

Note that the present invention is not limited to the electronic camera of the above embodiment, but can be applied to other information processing apparatuses.
