Next, switches SM to SE will be explained.

SM is a main switch for starting the camera including the printer section, and corresponds to the switch 104 shown in FIG. 1(A). SR is a start switch that is operated as a shooting start button when performing a photographing operation and as a print start button when performing a printing operation, and is operated as a start button 1 shown in Fig. 1 (A).
This corresponds to 05. SP is a switch that is turned on when the movable part 101a is pulled out, and detects that the printing operation has started.

ST functions as a switch to switch the photographing lens 102 to the telephoto side during photographing operation, and on the other hand, it serves as a switch for sequentially reproducing the images stored in the internal memory on the display unit 106 during printing, playback, etc. other than photographing operation. The switch 107 shown in FIG. 1(A) works as an access button.
corresponds to

When this ST functions as a forward access button, the next stored image is played back each time it is turned on. The sW functions as a switch to switch the photographing lens 102 to the wide side during photographing operations, while the images stored in the internal memory are sequentially displayed on the display unit 1 during printing, playback, and other operations other than photographing operations.
This functions as an access button for reverse playback, and corresponds to the switch 108 shown in FIG. 1(A). When this SW functions as a reverse access button, the previous stored image is played back every time it is turned on.

SV is a switch that, when turned on, outputs the image stored in the internal memory to a TV (not shown) connected to the camera body, and corresponds to the switch 110 shown in FIG. 1 (A>). By turning it on, the operator can enlarge and view the photographed image on the attached TV screen.

SF is a switch for erasing recorded images, and corresponds to the switch 112 shown in FIG. 1(A). When this switch SE is turned on during printing or TV playback, the image displayed on the monitor is erased from the internal memory.

The CPU 301 determines the output state of the switch SP, that is, whether the movable part 101a is in the retracted state or in the pulled out state, and activates the start switch SR.

The functions of switches ST and SW are changed over.

In addition, the switches SP, ST, SW and SM are respectively A.
These signals are input to the ND circuit ANI, and when one of them is turned on, an interrupt INT, which will be described later, is processed.

Next, FIG. 3 is a block diagram of the COD, memory and printer sections.

In the figure, a CCD 401 is a solid-state image sensor equipped with an electronic shutter function as described above, and has RlG and B stripe filters.

The C0D-TG402 is for supplying control signals and clocks to each circuit in this block, and is used to generate shutter operation control signals for the CCD401, image signals@readout driving clocks φv1φH, R8, pulse generation for the CD5403, and A Generates a serial clock to the /D converter 404 and a serial clock to the address controller 406.

Although an 8-bit D converter 4.04 is used, an appropriate number of bits can be selected depending on the required image quality. The internal memory 4.5 is a SRAM having a short access time, for example, and is used to take in serial data from the CCD 401 and store image data. This internal menu 1405 has a work area which is used during image processing in addition to an image area which has a storage capacity of at least one frame of captured images.

The Cosezza 407 performs each digital signal processing on the image data in the flowchart shown in FIG. 4.The image data in the internal memory 405 is stored in the format shown in FIG. After the data is subjected to WB processing and γ correction processing, it is written to the same address again.

Note that the WB processing is performed using a ROM table 408 in which conversion coefficients predetermined for color temperature information from the WB sensor 415 are stored.
The γ correction process converts the color-converted data to an RO in which predetermined conversion coefficients are stored.
Data is further converted via M table 4.08.

Regarding the function of this processor 407, the internal memory 4
The case of outputting from 05 to a printer and the case of outputting to a TV will be explained separately.

In the case of output from a printer, the following processing is performed for each line of each color of the transfer ink film 201 on each R, G, and B data obtained by the W'B correction processing. That is, first, a matrix is assembled to create data for the complementary color or black that is being processed at the time. The created data is subjected to gamma correction processing using the ROM table 408, and this processed data is sequentially converted into area gradation data for the printer and written into a line sequentialization memory 409, which will be described later. During this processing, a work area in the internal memory 405 is used for temporary storage of processing data.

Note that area gradation converts the color intensity of each pixel into the number of printed dots out of 16 dots consisting of, for example, 4 bits x 4 pits, as will be described later.

On the other hand, in the case of TV ratio output, the process shown in the flowchart in FIG. 4 is performed for each line, and the results are written into the video output memory 413.

Next, the line sequentialization memory 409 slices the area gradation data processed by the processor 407 for each bit and outputs it to the buffer 410 when outputting to a printer. That is, the 4-bit x 4-bit data written by the processor 407 is broken down into four pieces of 1-bit x 4-bit data and sent to the buffer 41 line by line.

The address controller 412 also includes a TV synchronization signal generation circuit (S

Note that the WB sensor 415 detects color temperature information of the subject, and 416 converts the analog signal of the WB sensor 415 into digital.

Next, the above 10-trick configuration will be explained in terms of operations during photographing, printing, and TV output.

(1) Operation during photography When the start switch SR is turned on in the photography mode, the CPU 301 outputs a start signal to the COD-TG 402 and drives the photometry section 303 to perform photometry. The exposure control unit 306 controls the aperture value Av obtained from the photometry results.
The aperture is controlled based on the exposure time Tv, and a shutter control signal is output to the C0D-TG 402 to expose the C0D 401.

After the exposure is completed, the CPU 301 switches the address controller 406 to output a serial signal, and outputs a read permission signal to the C0D-TG 402. As a result, the image data captured in the C0D 401 is transferred to the internal memory 405. After transfer, CPU3
01 connects the address controller 406 to the processor 407
It switches to the side to perform communication and outputs a command signal to process the image data as detailed in the flowchart of FIG. The processed image data is then stored in the internal memory 405 again.

With this, one photographing operation is completed. In preparation for the next photograph, the CPU 301 uses the address controller 40 to transfer the write address in the internal memory 405 to the next frame.
6 to switch the address and wait.

(2) Operation during printing When the CPU 301 is in the print mode, the CPU 301 starts the printing operation by detecting a print start command.

First, the CPU 301 causes the address controller 406 to select a page in the internal memory 405 in which an image to be printed is stored, and the processor 407
commands signal processing for printing.

The processor 407 receives instructions from the CPU 301,
First, γ correction is performed, and then the image data is read out from the internal memory 405, and the image data is read out from the internal memory 405, for example, Cy (cyan), Ye (yellow), M
The above-described area gradation processing is performed in the order of CI (magenta) and Bk (black) ink colors. In this process, first, data regarding Cy is created, and then area gradation is performed using the ROM table 4.08, and the data is written into the line sequentialization memory 409. The processor 407 outputs an end signal to the CPU 301 every time the processing for one line is completed.

When the CPU 301 detects the end of the processing for one line, it controls the buffer 410 and the head 411 to
Executes printing of lines. Each time the printing operation for one line is completed, the head 411 is moved for one line as shown in FIG.
) in the direction of the arrow and shift to the next row of pudding 1-.

In this way, the printing process for one image for one color is completed.

When the printing process for one color Cy is completed, the same printing process as described above is repeated in the order of Ye, Mq, and Bk, thereby completing the printing process for one image.

Alternatively, the head 420 may be moved by one line to form an image for one frame each time the printing process for four colors is completed for each line.

(3) Operation during TV output When the CPU 301 detects that the TV playback mode is entered, it starts the operation for TV playback. CPU30
1 is the internal memory 4 for the address controller 406.
05 in which an image to be reproduced on TV is stored, the processor 407 and address controller 412 are enabled to communicate with each other, and the processor 407 is commanded to perform signal processing for TV reproduction.

Processor 407 receives instructions from CPU 301,
The image data is read line by line from the internal memory 405, various processes described below are performed, and the resulting NTSC signal is written into the video output memory 413. At this time, not only image data but also horizontal and vertical synchronization signals are added. Furthermore, if the original image is a field image with a horizontal line density of 1/2, pseudo frame image processing is performed when writing to the video output memory 413, and one frame image is stored in the video output memory 413. do it like this. Then, when the processing for one frame is completed, the ``1 setter 407 is
Outputs an end signal to U301.

When the CPU 301 detects the end signal, it switches the address control 1 caller 412 to NTS C output,
This causes the video output memory 413 to output an NT-8C signal, and also operates the D/A converter 414 to output an analog TV signal.

Photographing, printing, and output to TV are performed according to each of the above modes.

FIG. 4 shows that the image signal of C0D401 is A/D converted,
A flowchart of data processing executed after being captured into internal memory 405 is shown.

First, in #11, WB correction is performed on the R and B signals so that they are at the same level as the G signal. This means that when an image of the reference white color is irradiated with light of the set color temperature using the color temperature coefficient determined by the color temperature information from the colorimetric system 415 and 416 mentioned above, the signal level is the same. It is corrected so that it becomes . This WB correction is performed 256 times (76
8/3), that is, it is performed for one line.

Next, in #12, γ correction is performed on the G signal and the WB-corrected R1B signal. This γ correction is also performed sequentially in the column (horizontal) direction for 20 rows in units of three RGB pixels as described above.

In #13, matrix processing is performed on the above-mentioned WB-corrected and γ-corrected signals using, for example, the calculation formula described later,
A low-band luminance signal (Y) and color difference signals (RY, B-Y) are created (#14).

Y =0.3OR+0.59G+0.111'3R-
Y=0.7OR-0, 59G-0, 118B-Y=0.
89B-0, 59G-0, 30R Next, in #15, low-frequency processing is performed on the luminance signal Y, and in #16, each of RlG and B is multiplied by a predetermined coefficient in order to reduce the aliasing distortion of each pixel. At the same time, the levels of R, G, and B, which form point-sequential signal levels in the high frequency region, are adjusted. This low range (#
15) and high frequency (#16) processing is also performed sequentially for one row in the column (horizontal) direction in units of three RGB pixels as described above.

When the above processing is completed, the band limits of the color difference signal and luminance signal are sequentially set (horizontally) as necessary in #17 and #18.
Do one line in the direction. Further, the low frequency Yg degree multiplied signal high frequency luminance signal obtained in #15 and #16 is added in terms of frequency to create a luminance signal (#19). This luminance signal creation process is sequentially performed 256 times in the column (horizontal) direction, that is, for one row.

After the above processing is completed, when this signal is to be played back on a TV, a burst signal and horizontal and vertical signals are added to the entire image to convert it into a standard television signal such as an NTSC signal (#20 ~ #22).

Next, FIG. 6 is a schematic diagram for explaining the operation of the thermal head, and FIG. 7 shows the transfer ink film 201.

In FIGS. 6(A) and 6(B), 201 is the aforementioned transfer ink film, and 220 is the transfer ink film 201.
221 is a supply member for the transfer ink film 201, and 411 is a thermal head. In the transfer ink film 201, as shown in FIG. 7, ink areas are formed at predetermined intervals in the order of, for example, CV, Ye, MO, and Bk. The predetermined interval is set to a width equal to or greater than the print size. A color band detection sensor 222 detects each color of the transfer ink film 201, and identifies the color of the ink located below the thermal head 411. As a result, line sequentialization memory 4
Image signals for each color output from 09 to the thermal head 411 are printed in the corresponding colors.

FIG. 6(A) shows the state before printing, for example, during photographing, and the winding member 220 and the winding drive system (not shown) are the camera body except for the movable part 101a shown in FIG. 1(B). It is located on the side. On the other hand, the supply member 221, the thermal head 411, the color band detection sensor 222, and its drive system are provided on the movable part 101a side.

Next, FIG. 6(B) shows a state in which the movable part 101a is pulled out, and a printing operation is performed by scanning the transfer ink film 201 with the thermal head 411 in contact with it. In this case, the supply member 221 remains in the movable part 101a, but the legal head 411 is moved as shown in FIG. 1(B).
Scan the pudding 1 frame 202 shown in the arrow direction. This scanning is repeated four times, that is, for four colors, and the photographed image is reproduced as a print using the composite color.

Next, FIG. 8 is a block diagram for explaining the configuration and operation of the printing section.

The CPU 301 controls the operation of this block as a whole. Reference numeral 431 denotes a print data creation unit comprising the aforementioned processor 407, line sequentialization memory 409, and the like. As described above, the buffer 410 converts the parallel data of the number of bits for one row supplied from the line sequential memory 409 into serial data and outputs the serial data to the head drive circuit 432. This head drive circuit 432 heats and drives the thermal head 411 using the output from the buffer 410.

The mechanical unit control circuit 433 controls each mechanical unit shown in FIG. 6 based on instructions from the CPU 301, and controls a head driving pulse motor 434 that drives the thermal head 411 in the scanning direction, and a winding of the transfer ink film 201. A transfer ink film winding motor 435 that drives the take-up member 220 and a color band detection sensor 222 are connected to each other.

The operation of the block configuration described above will be explained.

When detecting that the CPU 301 has entered the print mode, it outputs a print command signal to the head drive circuit 432. The head drive circuit 432 drives the thermal head 411 from one row of driver 1 to data supplied from the buffer 410 based on a print command signal from the CPU 301.
A heating signal is generated to print the Cy color on the first line. Then, the head driving pulse motor 434 moves the thermal head 411 one line above the print frame 202 in the direction of the arrow shown in FIG. 1(B). By alternately repeating this Cy color printing and moving the thermal head 411 to perform surface scanning, the first color printing in Cy color is completed. After that, the CPU 301 drives the thermal head 41 by the head driving pulse motor 434.
1 is returned to the reference position, that is, the first row, and the transfer ink film 201 is driven to be wound by one color by the transfer ink film winding motor 435 to set the Ye color. Then, as described above, printing in Ye color and movement of the thermal head 411 are repeated alternately to perform surface scanning, thereby completing printing in Ye color. Thereafter, the same procedure is performed for the MO color and the Bk color, and in this way, the print reproduction of the image using the composite color is completed. Note that the head 411 is not limited to a one-dimensional elongated shape, and may be a point-shaped head, for example.

In this case, the mechanism control circuit 433 is designed to control the head drive pulse motor 434 to move the head in the row and column directions to scan the surface, thereby printing one screen of images. Further, instead of the above printing method, each of the colors Cy, Ye, Mo, and Bk may be printed for each line as described above.

FIG. 9 is a block diagram when a monitor display is performed on the display unit 106.

In the figure, the same numbers as in FIGS. 3 and 4 indicate the same items. The character output memory 440 is the display unit 1
06 is, for example, a RAM, in which character data sent from the CPU 301, such as the frame number displayed with the image, printing in progress, printing completion, etc., are written. Also, R
A character generator that outputs predetermined character data in response to an instruction signal from the CPU 301 may be used instead of AM.

The compositing unit 441 is for configuring one screen by composing video output and character output. The display device a442 is, for example, a liquid crystal TV monitor having the display unit 106, and is a D/
The signal input from the A converter 424 is displayed on the monitor. The drive circuit 443 scans the display screen of the display unit 106 and applies voltage to the liquid crystal element.

The monitor display on the display unit 106 is performed during printing.
Alternatively, since it is during TV playback, the stored image is played back on the display unit 106 every time the access button ST or SW is turned on after the print operation transition switch SP or TV output switch SV is turned on.

First, when reproducing an image, as explained in Fig. 4,
Image data processed for TV output is stored in the video output memory 413. This image data can be accessed using the access button S.
This is stored in the piece in the internal memory 405 selected by T or SW.

On the other hand, the display of the frame number, printing in progress, printing completed, etc.
Data from CPt, 1301 is processed within processor 407 and stored in character output memory 440. Then, the character data in the character output memory 440 and the image data in the video output memory 413 are combined into one screen by a combining section 441. That is, a frame number and an image corresponding to the frame number are displayed. The synthesized data is then led to the display device 442 via the D/A converter 414 and displayed. After the image is displayed on the monitor as described above, when the start switch SR is turned on, the image displayed on the monitor is printed as described above.

In each of the block diagrams of the camera described above, the operation of the camera will be explained with a focus on the photographing operation based on the charts in FIGS. 10 to 13.

Then, when the main switch SM is turned on (YES in #100), or if it is already in the A state when the power supply is installed, the interrupt (INT) described later is enabled (#104), and the process returns to #105. move on.

In #105, it is determined whether the start switch SR has been pressed and changed from off to on. If the start switch SR is not pressed (No in #105), return to #100 and perform the steps in #10 above. Repeat the routine from O to #104.

Determine whether the charge storage capacitor in 05 has already been charged with the charge necessary for light emission, and if charging is not completed (No in #112>, set the unfilled flag ii 1
When charging is completed (YES at #112), proceed to #115. In #115, charging is stopped after confirming the completion of charging, and in #116 it is determined whether the uncharged flag is ``1''. If the unfilled flag is ``1'' (YES in #116).
S), set this unfilled flag to '0' in #117 and wait until the start switch SR becomes A (#118
). Then, when the start switch SR is turned off (111
8 (YES), return to #100 and perform the so-called release [cock]. On the other hand, if the unfilled flag is 'O'' in #116, the process moves to #119 and the subroutine of exposure control 2 shown in FIG. 13 is executed.

In FIG. 13, first, in #401, lNl- is prohibited, and the exposure time Tv and aperture value Av obtained from the photometric calculation are
is output to the exposure control section 306 (#402). The exposure control unit 306 drives the aperture of the camera 1 based on these data, and outputs a shutter control signal to the C0D-TG 402 according to the exposure time Tv to control the CCD.
401 exposure is performed. The CPU 301 is an exposure control unit 306
When a signal indicating that exposure has started is input from (
#403), a timer within the CPU 301 is started based on the flash emission timing determined in #111 (#404). The light emission of this flash is CCD4
This is performed at a timing after a predetermined period of time has elapsed from the start of exposure in 01. Next, the CPU 301 determines whether an exposure completion signal has been input from the exposure control unit 306 (#405). This determination is made because the exposure time Tv is a predicted value. For example, if the subject brightness suddenly increases during the counting operation of the flash emission timer, the exposure control unit 306 This is because there are cases where the exposure completion signal is output. That is, when the exposure control unit 306 outputs the exposure completion signal before the flash emission timing (#406
(YES in NO2#405), the exposure operation is ended without firing the flash. On the other hand, if the flash firing timing is reached before the exposure is completed (, #4
06: YES), the flash is emitted and a shutter close signal is output to the exposure control unit 306 (#407
．． #408), the exposure operation is ended.

When this exposure operation is completed, control is performed to write the image signal captured by the COD 4.01 into the internal memory 405 of the camera body 101 (#409). When the above processing is completed, INT is enabled in #410 and the process returns.

On the other hand, at 70-yards in Figure 10, the photometry results show a low Q! If it is determined that it is not a degree (NO in #109),
The subroutine of exposure control 1 without flash emission shown in FIG. 12 is executed (#110).

In FIG. 12, first, INT is prohibited in #301, and the exposure time Tv and aperture value Av obtained from the photometric calculation are output to the exposure control section 306 (#302). The exposure control unit 306 drives the aperture of the camera body 101 based on these data, and outputs a shutter control signal to the C0D-TG 402 according to the exposure time Tv to expose the C0D 401. When the CPU 301 receives a signal indicating that exposure has started from the exposure control unit 306 (#303), it starts a timer for measuring the camera shake limit time (#304).

This camera shake limit time indicates the maximum exposure time at which photography can be properly performed without camera shake, and becomes a problem when a relatively long exposure time without flash emission is required.

After starting the above-mentioned timer, the exposure control section 3
Determine whether the exposure completion signal is output from 6 (
#305). When the exposure time Tv is reached before the camera shake limit time elapses (No in #306), the exposure control unit 306
outputs an exposure completion signal (YES in #305) and ends the exposure operation. On the other hand, if the timer count completes before the exposure is completed (Y[S in #306), the CPU 301 will forcibly output a shutter close signal to the exposure control unit 306, assuming that the camera shake limit time has been reached (#307). , ends the exposure operation.

When this exposure operation is completed, control is performed to write the image signal captured by the CCD 401 into the internal memory 405 of the camera 1 (#308), similar to the processes #4o9 to #410 in the exposure control 2 routine. When the above processing is completed, TNT is enabled in #309 and the process returns.

Returning again to the flowchart in FIG. 10, the above #11
0 or #119 (When the exposure control subroutine ends, the process moves to #120, where the frame number is updated by 1, and this is displayed on the display section 106.Next, the shooting of all frames is completed. When all frame valves in the internal memory 405 have been photographed (YES in #121), a display or audio warning is issued in #122 to call the photographer's attention.If recording is possible, the warning will not be issued. Not done.

Then, move to #123 and start switch S R = 3
5- When the start switch SR is turned off (YES in #123), the CPU 301 outputs the signal (P
) is output, the power of the C0D 401 is turned off, and shooting for one frame is ended (#124). After the above processing, it is determined whether the flash has been fully charged for the next photograph (#125). If charging is not completed (NO in #125), set the incomplete charging flag to 1'' and start charging to complete charging (#12
6, #127). On the other hand, if charging is completed (#12
5: YES), the incomplete charging flag is set to II O11 and charging is stopped. (#128, #129). After this, the process returns to #100 and the operations from #100 to #129 described above are repeated.

Next, from #104 onwards when INT is enabled, the processing executed when this INT occurs and IC is detected will be explained with reference to the flowchart of FIG. This INT includes switch SP that detects transition to print operation, switch SV1 that instructs TV playback, and access button 5TXSW.
Occurs when one of the is turned on.

When this iNT occurs, the unfilled flag is set to “
1°', and if it is '1', it is assumed that INT has occurred while charging the charge storage]
Once charging is stopped at 202, and if it is 110 II, #
202 is skipped, and in #203 it is determined whether the switch SP is on.

If the switch SP is on (YES in #203), it is determined that the movable part 101a has been pulled out and the printing operation has started, and the process proceeds to #204. On the other hand, if the switch SP remains off (NO in #203), the process proceeds to #204. ), proceed to #223. #20
In step 3, a display indicating that the camera is currently in print mode is displayed, and then the access button ST is turned on from A.
That is, it is determined whether or not it has been pressed (#205). When the access button ST is turned on (YES in #205),
The process moves to #206, and if the access button ST is off, remains on, or is turned off from on (No in #205)
, moves to #210.

At #206, it is determined that the access button ST has been pressed, and the frame number is incremented by 1 and displayed on the display section 106, and the address control [1-RA 406.412 corresponds to this frame number] Address data corresponding to the frame number is output in order to reproduce the image (#207'). #
After waiting for the time required for the above processing in step 208, image information corresponding to the current frame number is displayed on the display unit 106 (#209).

Then, the process returns to #205, and the process of incrementing the frame number by 1 each time the access button ST is turned on and displaying the image corresponding to the frame number on the display unit 106 is repeated. On the other hand, in #210, it is determined whether the access button ST is on, and if it is on (YES in #210), #2
Return to 05, if off (No in #210), #21
Move to 1.

Next, when the access button SW is turned on instead of the access button ST (YES in #211), the process moves to #212, and when the access button SW is turned off or remains on, or is turned off from on (# If NO in 211, the process moves to #216.

At #212, it is determined that the access button SW has been pressed, and the frame number is decreased by 1 and displayed on the display section 106, and the address control [1-RA 406.412 plays back the image corresponding to this frame number. For this purpose, the address data corresponding to the frame number is output (#213>. After waiting for the time for the above processing in #214, the image information corresponding to the current frame number is displayed on the display unit 106 on the monitor ( #21
5>.

Then, the process returns to #211, and the process of decrementing the frame number by 1 each time the access button SW is turned on and displaying the image corresponding to the frame number on the display unit 106 is repeated. On the other hand, in #216, it is determined whether the access button SW is on, and if it is on (YES in #216), #21
Return to 1, and if it is off (No in #216), #250
to move to.

In #250, it is determined whether the erase switch SE is turned on. When this erase switch SE is turned on (#
250: YES), the image displayed on the monitor on the display unit 106 is erased (#251), and the process moves to #203. On the other hand, when the erase switch SE is not turned on (#2
No> at 50, move to #217 and press start switch SR
Determine whether the is turned on.

If the start switch SR is not turned on (NO in #217)
), it is determined that printing is not to be performed, the process returns to #203, and the above process is repeated. On the other hand, when the start switch SR is turned on (YES in #217), the CPU 301 outputs a print 1~command signal to the processor 407 (#218) in order to proceed to the print operation. Processor 407 receives the above signal and starts signal processing for printing operation. On the other hand, the CPU 301 displays on the display unit 106 that printing is in progress, and also controls the printing operation described above (#219, #220).

In #221, the process waits for printing to be completed, and when a print completion signal is output (YES in #221), a display indicating print completion is turned on (#221). With the above operations, printing for one frame is completed, and the process returns to #203.

On the other hand, if the switch SP is not turned on in #203, it is determined that no printing operation will be performed and the process moves to #223. That is, in #223, it is determined whether the TV playback switch SV is turned on. If the TV playback switch sV is off (No in #223), it is determined that no playback display will be performed on the TV, and the process moves to #235. On the other hand, if the TV playback switch Sv is turned on (#223)
(YES), a playback mode indicating that playback will be performed on the TV is displayed (#224).

In this playback mode, it is then determined whether the access button ST or SW is turned on (#2
2.5, #230). If the access button ST is off, remains on, or is turned off from on (No in #225)
On the other hand, when the access button ST is turned on (YES in #225), the piece number is increased by 1 and displayed, and the address control [Cola 4-06
．． 412 outputs address data corresponding to this frame number in order to reproduce the image corresponding to this frame number (#22
6, #227). Next, as described above, the image information corresponding to the current piece number is displayed on the TV monitor (#228
). Then, the process returns to #225, and the process of incrementing the frame number by 1 each time the access button ST is turned on and displaying the image corresponding to the frame number on the TV is repeated. on the other hand,#
In step 229, it is determined whether the access button ST is on. If it is on (YES in #229), the process returns to #225; if it is off (No in #229), the process moves to #230.

Next, when the access button SW is turned on instead of the access button ST (YES at #230), the process moves to #231, and on the other hand, when the access button SW is turned off, remains on, or is turned off from on. (No in #230>, move to #234.

At #231, it is determined that the access button SW has been pressed, and the frame number is incremented by 1 and displayed, and the address controllers 406 and 412 select the frame number corresponding to this frame number in order to play back the image corresponding to this frame number. Output address data (#231, #232). Next, as described above, the image information corresponding to the current frame number is displayed on the TV monitor (#233>.Then, the process returns to #230, and the frame number is decremented by 1 each time the access button SW is turned on. , the process of displaying the image corresponding to the frame number on the TV is repeated.Meanwhile, in #23/l, it is determined whether the access button SW is on, and if it is on (Y in #234).
ES), return to #230, and if it is off (N at #234)
o), move to #252.

In #252, it is determined whether the erase switch S[ has been turned on. This erase switch SF is on sale (#
If the erase switch SE is not turned on (NO in #252), the process returns to #203.

Steps after #235 are a routine for determining access buttons ST and SW when photographing, that is, when not during pudding 1 or later and during TV playback. When access button S]- is turned on (YES in #235), switch the photographing lens 102 to the telephoto side (#2
36>, when the access button SW is turned on (Y in #237)
ES), switch the Ili shadow lens 102 to the wide side (
#238>. When access buttons ST and SW are both off, lens switching is not performed. Then, at the end of this INT routine, it is determined whether the unfilled flag is '1''(#239). If the unfilled flag is 1''(#
239 (YES), INT occurred during charging,
Resumed the charging operation that had been interrupted in an uncharged state (
After #240), the process returns, and if the unfilled flag is 0'', the process returns as is.
