Next, photographing 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, when 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 (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.

Int Photographic Experts Group), and is recorded in the captured image recording area of the memory card 24. 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.

When the continuous shooting mode changeover switch 13 is switched to the S mode, only one frame is shot. 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, a 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 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.

The light image of the 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 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 an A / D conversion circuit 32, where it is digitized and output to a 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. 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, the 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.

An image signal sampled by the image processing section 31 (an image signal of one-ninth of all the pixels of the CCD 20) is supplied to an A / D conversion circuit 32, where it is digitized and output to a 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 date and time of the photographing. The header information is recorded in the captured image recording area of the memory card 24 along with the header information.

It is to be noted that the strobe 4 can be operated to irradiate the subject with light as required. 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 by 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 and the 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 a line drawing color displayed on the LCD 6 from colors such as black, white, red, and blue.

When the execution key 7B of the operation key 7 is pressed after the input of the line drawing information to the touch tablet 6A by the pen 41, the line drawing 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.

Further, 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.

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 symbol "*" indicates that a predetermined memo is recorded as line drawing information.

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 (when no audio information is input, Do not show).

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 specify 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 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 is sensitive 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 section 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.

In the present embodiment, FIG.
As shown at 0, the electronic camera 1 and the APS camera 100 are connected by the interface cable 70, and information can be exchanged between them.

As shown in this figure, the electronic camera 1 is fixed to the upper part of the APS camera 100 by a connecting member 200. Since the optical axis of the photographing optical system (photographing lens 3) of the electronic camera 1 is adjusted so as to face the same direction as that of the APS camera 100, these two cameras can capture the same subject. It is.

FIG. 11 is a diagram showing a configuration example of the APS camera 100. In this figure, the control circuit 119 includes C
It is composed of PU, RAM, ROM, etc., and controls various operations of the apparatus. Timing circuit 1
Numeral 20 measures time. RAM1
Reference numeral 21 is used to record shooting information such as an aperture value and a shutter release time during shooting. The photo-reflector 107 generates a signal for determining one frame of a film, which will be described later, and a signal for ending the writing of information.

The photo-reflector 122 detects a perforation of the film described later and generates a signal for determining the write frequency of the magnetic head H and a signal for ending the writing of information. The photometric sensor 104 measures the amount of ambient light when performing automatic exposure.

The switch 117 detects the amount of light (photometry).
Is operated when the sequence for measuring the distance (ranging) is started. A release switch 118 (operation means) is a switch for starting a sequence of opening a shutter and feeding a film, and is provided above the APS camera 100 as shown in FIG.

The motor 108 is a motor for feeding a film, and feeds a predetermined amount of film at the time of photographing. The motor driver 128
8 is driven.

The distance sensor 108a is constituted by, for example, an ultrasonic sensor or the like, and measures the distance to the subject. The photographing lens 101 (incident means) condenses light from a subject and converges on a predetermined position of the film F. The lens actuator 102a moves the photographing lens 101 appropriately in the optical axis direction. Lens encoder 102
b generates a position signal indicating the current position of the taking lens 101.

The shutter 103 is opened for a predetermined time during photographing, so that light from a subject enters. The encoder 123 encodes predetermined information about the subject (details will be described later) output from the control circuit 119. Buffer 12
Numeral 4 temporarily stores data output from the encoder 123. Head amplifier 125
The (writing unit) amplifies the signal output from the buffer 124 with a predetermined gain and supplies the amplified signal to the magnetic head H.

The magnetic head H generates a magnetic field in accordance with the output voltage of the head amplifier 125, and records information on a magnetic recording track of the film F. Pad 1
Numeral 11 indicates that the film F is brought into close contact with the magnetic head H. The pad advance / retreat control mechanism 112 controls the pad 111 so that the magnetic head H is in close contact with the film F when the film F is fed.

The buffer 127 is adapted to temporarily store the signal read from the magnetic recording track of the film F by the magnetic head H and amplified by the head amplifier 125. The decoder 126 decodes the information stored in the buffer 127 to reproduce the original information and supplies it to the control circuit 119.

The interface 129 (transmitting means, receiving means) exchanges information with the electronic camera 1 via the interface cable 70.

FIG. 12 is a view for explaining a detailed configuration example of the film F. As shown in this figure, a perforation 141 is formed on the film F, and the magnetic head H
A signal for determining the write frequency of the data and a signal indicating the end timing of writing the information are generated. The magnetic recording tracks 142 and 143 are
The surface of the film F is formed by applying a magnetic material, and information to be described later is recorded. The cartridge 144 is configured to wind and store the film F therein.

The magnetic recording track 142 records information such as the number of prints of each frame when developing the film F and the title of each frame. The magnetic recording track 143 records information such as a white balance adjustment value, a shutter speed, and a focal length of a used lens.

Next, the operation of the above embodiment will be described.

FIG. 13 is a view for explaining an example of the processing executed in the electronic camera 1. This program is
It is stored in the memory card 24. The program may be supplied to the user in a state stored in the memory card 24 in advance, or may be stored in a CD-ROM (Compact Disc-ROM) or the like so that the program can be copied to the memory card 24. May be supplied to the user.

When the processing shown in FIG. 13 is executed, in step S1, the CPU 39 of the electronic camera 1 refers to the output of the interface 48 and determines whether or not the release switch 118 of the APS camera 100 has been pressed. As a result, the release switch 118 of the APS camera 100
If it is determined that is not pressed (NO), the process returns to step S1, and the same processing is repeated until the release switch 118 is pressed. If it is determined that the release switch 118 has been pressed (YES), the process proceeds to step S2.
Proceed to.

At step S2, the electronic camera 1 executes a photographing process. That is, the light image of the subject incident from the CCD 20 is sampled by the image processing unit 31, converted into a digital signal by the A / D conversion circuit 32, compressed by the DSP 33, and captured by the memory card 24. Stored in the recording area. Also,
The captured image is displayed on the LCD 6 as shown in FIG. In this display example, an image of a person is displayed.

In the following step S3, a white balance adjustment value is obtained. That is, the CPU 39 controls the photometric circuit 5
1 and the colorimetric circuit 52 to receive the photometric result of the photometric element 16 and the colorimetric result of the colorimetric element 17. Then, the CPU 39 calculates a white balance adjustment value corresponding to the color temperature supplied from the colorimetric circuit 52 with reference to a predetermined table.

At the step S4, the CPU 39 sets the LCD
6, a title input window is displayed, and the input of the title of the captured image is accepted. FIG. 15 shows a display example when a title input window is displayed on the display screen shown in FIG. In this example, FIG.
Is displayed at the top of the screen displaying the image of the person shown in FIG. A window for inputting a title is displayed below the window. In this example, the title “TANAKA” is input. In addition, such a character input is, for example, by handwriting character recognition software or the like.
This is made possible by converting a handwritten input character into a text code.

When the enter key 7B is pressed after the title is input, it is determined in step S5 that the title has been input (YES), and the flow advances to step S6. If the execution key 7B has not been pressed, the determination in step S5 is NO, and the process returns to step S5 to repeat the same processing until the execution key 7B is pressed.

Note that the enter key 7
When B is pressed, a null code (for example, “0”) is used as a title to indicate that no title has been input.

In step S6, the CPU 39 sends a message prompting the user to input the number of prints during development.
Display on D6. FIG. 16 shows a display example of a screen on which such a message is displayed. In this display example, the title input in steps S4 and S5 is displayed at the top of the screen. At the bottom of the screen, a message prompting the user to input the number of prints is displayed. In this example, “1” is input as the number of prints.

After the number of prints has been input,
If B is pressed, it is determined in step S7 that the number of prints has been input (YES), and the flow proceeds to step S8. If the execution key 7B has not been pressed, the process returns to step S7, and the same processing as described above is repeated.

When the enter key 7B is pressed without inputting the number of prints, the default value "1" is set.
Is the number of prints.

In a succeeding step S8, the CPU 39 sends the title, the number of prints, the white balance adjustment value and the like to the APS camera 1 via the interface 48.
Transmit to 00. Then, the process ends (END).

FIG. 17 is a flowchart illustrating an example of a process executed by the APS camera 100 when the process of FIG. 13 is executed by the electronic camera 1. This program is stored in the RAM 121. This program may be supplied to the user in a state stored in the RAM 121 in advance, or may be supplied to the RAM 121.
CD-ROM (Compact Disc-RO
M) or the like, and may be supplied to the user.

When the processing shown in FIG. 17 is executed, the APS
In step S30, the control circuit 119 of the camera 100 determines whether the release switch 118 has been pressed. As a result, when it is determined that the release switch 118 has not been pressed (NO), the process returns to step S30, and
The same processing is repeated until the release switch 118 is pressed. Further, the release switch 118 is pressed (Y
If it is determined as ES), the process proceeds to step S31.

At step S31, the release switch 1
The information indicating that the button 18 has been pressed is transmitted to the interface 12.
9 to the electronic camera 1. As a result, the electronic camera 1 determines in step S1 of FIG. 13 that the release switch 118 has been pressed (YES), and proceeds to step S2.

Returning to FIG. 17, in step S31, the control circuit 119 determines whether or not the interface 129 has received the information about the subject transmitted by the electronic camera 1. As a result, when it is determined that the information transmitted by the electronic camera 1 has not been received (NO), the process returns to step S32, and the same processing as the above-described case is repeated. If it is determined that the information transmitted by the electronic camera 1 has been received (YES), the process proceeds to step S33.

In step S33, the control circuit 119
With the processing in step S8 in FIG. 13, the information (title, number of prints, and white balance adjustment value) about the subject sent from the electronic camera 1 is read from the interface 129 and supplied to the encoder 123. As a result, the encoder 123 encodes the subject information supplied from the control circuit 119, and
4 The information temporarily stored in the buffer 124 is supplied to the head amplifier 125, amplified with a predetermined gain, and supplied to the magnetic head H. Magnetic head H
Generates a magnetic field according to the output voltage of the head amplifier 125, and writes information on the subject to the magnetic recording tracks 142 and 143. Then, the process ends (END).

According to the above-described processing, when photographing is performed by the APS camera 100, the electronic camera 1 also performs photographing at substantially the same timing. Then, since the image photographed by the electronic camera 1 is displayed on the LCD 6, it is possible to immediately confirm the quality of the image.

Therefore, when the photographed image is not good (for example, when the person who is the subject closes his or her eyelids during photographing), inputting “0” as the number of prints at the time of development makes it unnecessary. It is possible to prevent a large frame from being developed. If the captured image is good, it is possible to input a title and a desired number of prints, and print additional photographs as needed. Note that the input title is printed on the back side of the photo.

The white balance adjustment value obtained in step S3 is referred to when developing the film F, and correction (for example, correction of white balance of illumination for exposure) is performed in accordance with this value. Adjusted for optimal print.

In the above embodiment, the processing in the case where one photograph is taken (in the case of single shooting) has been described. However, the present invention can be applied to the case of continuous shooting. FIG. 18 is a flowchart illustrating an example of a process corresponding to continuous shooting.

The program for this processing is stored in the memory card 24 as in the case described above. The program may be supplied to the user in a state stored in the memory card 24 in advance, or may be stored in a CD-ROM (Compact Disc-ROM) or the like so that the program can be copied to the memory card 24. May be supplied to the user.

When this processing is executed, step S50 is executed.
In, the CPU 39 of the electronic camera 1 refers to the output of the interface 48 and determines whether the release switch 118 of the APS camera 100 has been pressed. As a result, if it is determined that the release switch 118 of the APS camera 100 has not been pressed (NO), step S5
Returning to 0, the same processing is repeated until the release switch 118 is pressed. If it is determined that the release switch 118 has been pressed (YES), the process proceeds to step S51.
Proceed to.

In step S51, the electronic camera 1 executes a photographing process. That is, the light image of the subject incident from the CCD 20 is sampled by the image processing unit 31, converted into a digital signal by the A / D conversion circuit 32, compressed by the DSP 33, and captured by the memory card 24. Stored in the recording area. The captured image is displayed on the LCD 6 in the same manner as described above.
(See FIG. 14).

In a succeeding step S52, a white balance adjustment value is obtained. That is, the CPU 39 controls the photometric circuit 51 and the colorimetric circuit 52 to receive the photometric result of the photometric element 16 and the colorimetric result of the colorimetric element 17. Then, the CPU 39 calculates a white balance adjustment value corresponding to the color temperature supplied from the colorimetric circuit 52 with reference to a predetermined table.

In step S53, the CPU 39 refers to the output of the interface 48 and determines whether or not the release switch 118 of the APS camera 100 has been pressed. As a result, if it is determined that the release switch 118 is still pressed (YES), step S51 is performed.
And the same processing (photographing processing) as in the above case is repeated. Also, the release switch 11 of the APS camera 100
If it is determined that 8 has not been pressed (NO), the process proceeds to step S54.

In step S54, the CPU 39 displays the photographed image on the LCD 6 in a divided manner. FIG.
Shows a state in which the photographed image is divided and displayed on the LCD 6. In this example, four consecutively shot images are displayed in the order in which they were shot, for example, at the upper left, upper right, lower left, and lower right.

When four or more images are continuously shot, it is possible to display the images on a plurality of pages. The number of divisions may be, for example, nine.

In a succeeding step S55, it is determined whether or not a specific image is specified among the images displayed in a divided manner. That is, when the execution key 7B is pressed after the specific image is specified by the pen 41, it is determined that the specific image has been specified (YES), and the process proceeds to step S56. If no image is specified, the process returns to step S55, and the same processing as in the above-described case is repeated.

At step S 56, CPU 39 enlarges and displays the designated image on LCD 6. That is, CPU3
Reference numeral 9 reads out image data corresponding to the image specified on the divided and displayed screen from the memory card 24, decodes the image data, and outputs the decoded image to the LCD 6. At this time, the number of frames of this image (information indicating the number of the image captured by the APS camera 100) is also obtained at the same time. Note that in order to acquire the information on the number of frames (the number of frames of the next image to be shot), it is necessary to read the information on the number of frames from the APS camera 100. Such information is stored in the electronic camera 1 and the APS camera. What is necessary is just to make it transmit from the APS camera 100 to the electronic camera 1 when 100 is mutually connected by the interface cable 70.

At the step S57, the CPU 39 sets the LC
A title input window is displayed on D6, and the input of the title of the captured image is accepted. For example, when the upper left image is selected on the divided display screen of FIG. 19, a screen as shown in FIG. 14 is displayed by the processing of step S57. Since this drawing has been described above, its description is omitted.

When the enter key 7B is pressed after the title is input, it is determined in step S58 that the title has been input (YES), and the flow advances to step S59.
If the execution key 7B is not pressed, the process proceeds to step S
NO is determined in step 58, and the process returns to step S58.
The same processing is repeated until the execution key 7B is pressed.

When the execution key 7B is pressed without inputting a title, a null code (for example, “0”) is given, indicating that the title has not been input.

In the step S59, the CPU 39 issues a message prompting the user to input the number of prints at the time of development.
It is displayed on the CD 6 (see FIG. 16).

On the screen shown in FIG. 16, when the number of prints is input and the execution key 7B is pressed,
In step S60, the number of prints is input (Y
ES), and the process proceeds to step S61. If the execution key 7B has not been pressed, the process returns to step S60, and the same processing as that described above is repeated.

When the enter key 7B is pressed without inputting the number of prints, the default value "1" is set.
Is the number of prints.

At the following step S61, the CPU 39 sets
The title, the number of frames, the number of prints, and the white balance adjustment value are transmitted to the AP via the interface 48.
The data is transmitted to the S camera 100. Then, the process proceeds to step S62.

In step S62, the CPU 39 determines whether or not the execution key 7B has been pressed. If it is determined that the execution key 7B has not been pressed (NO), the processing proceeds to step S5.
4 and the same processing as in the above case is repeated. Also,
If it is determined that the execution key 7B has been pressed (YES), the flow proceeds to step S63.
