Next, FIG. 3 is a block diagram of the CCO, memory, and printer section.

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

C0D-TG402 is ill for each circuit in this block.
This is for supplying the II-fold signal clock, and the CCD
Generates a shutter operation control signal for 401 and image signal read drive clock φv1φH, R8, generates a pulse for CD5403, generates a serial clock for A/D converter 404, and generates a serial clock for address controller 406.CD S 403 Ha CCD
40117) Sampling is performed on the output image signal for double correlation. A/D converter 40
4 converts the analog output image signal of the CCD 401 into digital data. In this embodiment, an 8-bit A/D:1 inverter 404 is used, but an appropriate number of bits can be selected depending on the required image quality. The internal memory 405 is a SRAM having a short access time, for example, and is used to take in serial data from the C0D 401 and store the image T-data. This internal memory 405 has a work area that is used during image processing in addition to an image area that has a capacity that can store at least one frame's worth of H shadow images.

The address controller 406 receives the clock from the C0D-TG 402 when taking in data from the CCD 401, and serially outputs the write address signal of the internal memory 405, and also decodes the I10 output and address signal output from the processor 407 for processing. internal memory 405
It is designed to output an address signal to. ROM
The table 408 is a white balance (hereinafter referred to as W) which will be described later.
The WB coefficient data for tgA and the γ correction coefficient data for color conversion for printers and TVs are stored in advance.

The processor 407 subjects the image data to various digital signal processes in the flowchart shown in FIG. The image data IJ in the internal memory 405 is stored in the format shown in FIG. .

Note that the W8 process converts the color temperature information from the WB sensor 415 into a ROM table 408 in which predetermined conversion coefficients are stored.
The γ correction process converts the color-converted data to an RO in which predetermined conversion coefficients are stored.
Further data conversion is performed via the M table 408.

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 printer output, 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 WB correction process. 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 to a line sequentialization mark 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, for example, 16 dots consisting of 4 bits x 4 bits, as will be described later.

On the other hand, in the case of TV ratio output, the processing shown in chart 70 in FIG. 4 is performed for each line, and the results are written into the video output memory 413.

Next, a line sequentializing method 409 slices the area gradation data processed by the processor 407 for each pit and outputs it to a buffer 410 when outputting to a printer. In other words, the 4-bit x 4-bit data written by the processor 407 is decomposed into four 1-bit x 4-bit arcs and sent to the buffer 41 line by line.

The address controller 412 converts the I10 output and address output from the processor 407 into one code, and
It generates an address signal to the video output memory 413 to which image data processed for images is transferred. In addition, the address controller 412 has a built-in TV synchronization signal generation circuit (SSG), and the video output memory 413
When outputting a composite signal from , the end of the even field picture and the beginning of the odd field picture are continuous to make it endless, and a read serial address is generated so that a pseudo frame image is created, and the signal is sent to the D/A converter 414. generates an output clock. The video output memory 413 is used to take in image data from the internal memory 405, temporarily store processed data during signal processing, and store the NTSC video signal that is the processing result. The D/A converter 414 converts the digital TV signal in the video output memory 413 into an analog signal and outputs it to a TV (not shown).

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

Regarding the above block configuration, the operation will be explained below in terms of the first time, print time, and TV output/output conversion number.

ml Operation during Shadow When the start switch SR is turned on in the photographing mode, the CPU 301 outputs a start signal to the CCD-TG 402 and drives the photometry section 303 to perform photometry.

The exposure control unit 306 controls the aperture based on the aperture value Av determined from the photometry results, and further outputs a shutter control signal to the C0D-TG 402 in accordance with the exposure time Tv 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 successive 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 m-sho operation is completed. Then, for the next shooting, the C0D 401 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 1301 is in print mode,
The printing operation is started by detecting the print start command.

First, the CPU 301 causes the address controller 406 to select the page in the internal memory 405 in which the image to be printed is stored, and also
7 to perform signal processing for printing.

Processor 407 receives instructions from 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-mentioned area li! in the order of Q (magenta) and 3K (black) ink colors. ! Perform i-toning processing. This process begins with C
Create data for y, and also create ROM table 40
Area gradation is performed using the table No. 8 and 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 print the one line. Each time this printing operation for one line is completed, the head 411 is moved for one line.
Move in the direction of the arrow in Figure (B) to prepare for printing the next line. 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, Mg, 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) When the TV output/output rotation operation C0D401 detects that the TVV raw mode has been entered, it starts an operation for TV reproduction. 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.

The processor L1 processor 407 receives a command from the CPU 301, reads image data line by line from the internal memory 405, performs various processes described below, and outputs the NTSG data as a result.
The signal is written to the video output memory 413. At this time, not only image data but also horizontal and vertical synchronization signals are added.

In addition, if the original image is a field image with a horizontal line density of 1/2, pseudo frame image processing is performed when reading into the video output memory 413, and one frame image is stored in the video output memory 413. Make sure that you are When the processing for one frame is completed, the program [1 setter 407
An end signal is output to the PU301.

When the CCD 401 detects the end signal, it switches the address controller 412 to NTSC output, thereby causing the video output memory 413 to output an NTSC signal, and operating the D/A converter 414 to output the NTSC signal.
] Output the 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 the CCD 401 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 is captured using 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, This is to correct the signals so that they are at the same signal level. This We correction is performed 256 times (
768/3), that is, it is performed for one line.

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

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 frequency i-degree signal (Y) and color signals (RY, B-Y) are created (#14).

Y -0゜30R+0.59G+0.118R-Y-
0,70R-0,59G-0,113B-Y=0.89
[3-0,59G-0,3ORNext, in #15, low frequency processing of H degree signal @Y is performed, and in #16, R is applied to reduce the aliasing distortion of each pixel.

Each of G and B is multiplied by a predetermined coefficient, and the levels of R, G, and B, which form point-sequential signal levels in a high frequency region, are adjusted. This low range (#15) and ^ range (#1
6) 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. Furthermore, a brightness signal is created by frequency-wise adding the low-range brightness signal and the n-degree signal obtained in #15 and #16 (#19). This brightness signal creation process is performed in sequential columns (horizontal). This is performed 256 times in the direction, or one line.

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 NTSG signal (#20 ~ #22).

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

In FIGS. 6A and 6B, 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 Cy, Ye, Mo, and Bk, for example. 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 within the movable portion 101a, but the thermal head 411 scans the print frame 202 shown in FIG. 1(B) in the direction of the arrow. When this scanning is repeated four times, that is, for four colors, the photographed image is reproduced as a print using the composite colors.

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 it 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 in the above block configuration 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 prints one line of dot data supplied from the buffer 410 based on a print command signal from the CPU 301.

A heating signal is generated from the -ta to the thermal head 411 to print the Cy color on the first line. Then, the head driving pulse motor 434 moves the thermal head 411 over the print frame 202 in the direction of the arrow shown in FIG. 1(B).
Move the line. 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 this, the CPU 301 controls the head drive pulse motor 4.
34 returns the thermal head 411 to the reference position, that is, the first row, and the transfer ink film 20 is moved by the transfer ink film winding motor 435.
1 is wound up and driven for one color 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. Below, M.O.
The same procedure is performed for the Elk 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 mechanical unit control circuit 433 controls the head drive pulse motor 434 to move the head in the row and column directions to perform surface scanning, and image 1
It is designed to print as much as a screen. Also, instead of the above printing method, Cy
, Ye, MO, and Bk may be printed.

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

It is, for example, a RAM, into which the frame number displayed along with the image, printing in progress, printing completion, etc., character data sent from CPI, 7301, etc. are written in 6. Also,
Instead of the RAM, a character generator that outputs predetermined character data in response to an instruction signal from the CPU 301 may also be used.

The compositing unit 441 is for configuring one screen by composing video output and character output. The display device 442 is, for example, a liquid crystal TV monitor having the display unit 106, and has a D/A
The signal input from the 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.
Or, since it is during TV playback, each time the access button ST or SW is turned on after the print operation transition switch 'fSP or TV output switch Sv is turned on,
The stored image is reproduced on the display unit 106.

This is stored in the piece within 05.

On the other hand, for displays such as No. 111, printing in progress, printing complete, etc., data from the C0D 401 is processed in the processor 407 and stored in the character output memory 440. Then, the character data of the character output melody 440 and the image data of 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. And the above synthetic data is D

3, perform photometry, exposure time Tv, aperture 11 A.
Calculate v (#108). Also, determine whether the subject is low IEII from the photometry results #'109)
, if it is determined that the brightness is low (YES in #109)
), To perform flash photography, first calculate the flash emission timing based on the photometric value (#111)
. Next, it is determined whether the charge storage capacitor in the flash unit 305 has already been charged with the charge necessary for light emission, and if charging is not completed (No in #112),
Set the uncharged flag to “1” and start charging #113,
#114), when charging is completed (YES in #112),
Proceed to #115. In #115, charging is confirmed to be complete and charging is stopped, and in #116 it is determined whether the unfilled flag is 1". If the unfilled flag is 1" (YES in #118), # At step 117, the unfilled flag is set to "OH" and the system waits until the start switch SR is turned off (#11
8). Then, when the start switch SR turns off (#1
18 (YES), return to #100 and perform the so-called release lock. On the other hand, if the unfilled flag is "0" in #116, the process moves to #119 and the exposure system t shown in FIG.
Execute subroutine l12.

In FIG. 13, first, INT is prohibited in #401, and the exposure time Tv and aperture value A obtained from the photometric PI4 calculation are
v 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 CC.
Perform D401 exposure. C0D401 is the exposure control section 30
When a signal indicating that exposure has started from step 6 is input (#403), a timer in the C0D 401 is started at the flash emission timing determined in step #111 (#404). The light emission of this flash is CCD
This is performed at a timing after a predetermined period of time has elapsed from the start of exposure 401. 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, (#40
6: NO9 #405: YES), the exposure operation ends without firing the flash. On the other hand, if the flash firing timing is reached before the exposure is completed (#40
6), the flash is emitted and a shutter close signal is output to the exposure control section 306 (#407).
．． #408), the exposure operation is ended.

When this exposure operation is completed, control is performed to write the image signal taken into the CCD 401 into the internal memory 405 of the camera body 101 (#409). When the above processing is completed,
At #410, enable INT and return.

On the other hand, in the flowchart of FIG. 10, if it is determined that the brightness is not low as a result of photometry (No in #109),
The subroutine of exposure control 1 without flash emission shown in FIG. 12 is executed (#110).

In FIG. 12, first, tNT is prohibited in #301, and the exposure time Tvs aperture value Av obtained from the photometric calculation is output to the exposure control section 306 (#302). The exposure control m+ unit 306 drives the aperture of the camera body 101 based on these data, and also sends a shutter control signal to the C0D-TG402 according to the exposure time Tv.
C0D401 is exposed. When the C0D 401 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 Q limit of the exposure time at which a picture can be properly taken without being able to take pictures by hand, 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). Before the camera shake limit time elapses (No in #306), the exposure time Tv1. : When reached, exposure control section 3
06 outputs an exposure completion signal (YES in #305),
Ends the exposure operation. On the other hand, if the timer count completes before the exposure is completed (YES in #306), the CPU 301 forcibly outputs a shutter close signal to the exposure control unit 306, assuming that the hand-capture limit time has been reached (#307).
Terminates 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 #409 to #410 in the exposure control 2 routine. When the above processing is completed, rNT is enabled in #309 and the process returns.

Returning to the chart in FIG. 10 again, the above #1
When the exposure control subroutine in step 10 or #119 is completed, the process moves to step #120, where the frame number is updated by 1, and this is displayed on the display section 106. Next, when the shading of the frame is completed and all the images in the internal memory 405 are completed (YES in #121), a warning is displayed or audible in #122 to call the photographer's attention. do. No warning will be issued if recording is possible.

Then, the process moves to #123 and waits until the start switch SR is turned off. When the l7II start switch SR is turned off (YES in #123), the CCD 401 outputs the signal (P).
Outputs 1 and turns off the power of CCD401.
The uniform division process ends (#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 (#126)
, #127). On the other hand, if charging is completed (#125
-(-YES), sets the unfilled flag to "0" and stops charging. (#128, #129). After this, the process returns to #100 and the operations from #100 to #129 described above are repeated.

Next, the first step is to explain the process to be executed when this INT occurs after #104 that enabled INT.
This will be explained using the flowchart shown in FIG. This INT occurs when the switch SP that detects transition to print operation, the switch Sv1 that instructs TV playback, and any of the access buttons ST and SW are turned on.

When this INT occurs, the unfilled flag is set to “ in #201.
1", and if it is "1", it is assumed that INT has occurred while charging the charge storage capacitor, and #20
At 2, charging is temporarily stopped and the value becomes “0′.

If so, skip #202 and determine in #203 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 print operation has started, and the process proceeds to #204. On the other hand, if the switch SP remains off, <No in #203. ), proceed to #223. #20
In step 3, a display is made to indicate that the camera is currently in print mode, and then it is determined whether the access button ST has been changed from off to on, that is, has been pressed (#205). When access button ST is turned on (YES in #205), #2
06, and when the access button ST remains on or is turned off from on (No in #205, #
The process 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 at the same time, the image corresponding to the frame number of address control [''-RA 406.412 Poko is played back. Therefore, the address data corresponding to the frame number is output (#207). After allowing time for the above processing in #208, the image information corresponding to the current frame number is displayed on the display unit 106 (#20
9).

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 cough 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 at #211), the process moves to #212, and when the access button SW remains on or is turned off from on (#211 (No), move on to #216.

In #212, it is determined that the access button sw has been pressed, and the frame number is incremented by 1 and displayed on the display unit 106, and the address controllers 406 and 412 change the frame number in order to reproduce the image corresponding to this frame number. Address data corresponding to the number is output (#213). After allowing time for the above processing in #214, the image information corresponding to the current frame number is displayed on the display unit 106 (#215
).

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), #2
Return to 11, if it is off (9216rNO), #2
501. :Transition.

In #250, it is determined whether the erase switch SE is turned on. This erasure occurs when switch SE is turned on (
(YES in #250), 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 (#
No> at 250, move to #217 and turn the start switch S
Determine whether R is turned on.

If the start switch SR is not turned on (No in #217)
), determines not to print and returns to #203,
Repeat the above process. On the other hand, when the start switch SR is turned on (YES in #217), the CPU 301 outputs a print 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 the printing operation will not be performed, and the process moves to #223. That is, in #223, the TV playback switch S
Determine whether the is turned on. If the TV playback switch S■ is off (NO in #223), it is determined that no playback display will be performed on the TV, and the process moves to #235;
When the TV playback switch S is turned on (Y in #223)
ES), a playback mode indicating that TV playback is to be performed is displayed (#224).

In this playback mode, it is next determined whether the access button ST or SW is turned on (#22
5, #230). Access button ST remains off or on,
Or when it is turned off from on (No in #225),
The process moves to #229, and on the other hand, when the access button ST is turned on (YES in #225), the frame number is incremented by 1 and displayed, and the address controller 406.41
2 outputs address data corresponding to this frame number in order to reproduce the image corresponding to this frame number (#226, #
227). Next, as described above, the image information corresponding to the current frame 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, #22
In step 9, it is determined whether or not the access button ST is on. If it is on (YES in #229), the process returns to #225, and 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.

In #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 display the frame number corresponding to the frame number in order to reproduce 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 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 TV is repeated. On the other hand, in #234, it is determined whether the access button SW is on, and if it is on (YES in #234).
S), return to #230, and if it is off (N in #234)
o), move to #252.

In #252, it is determined whether the erase switch SE is turned on. When this erase switch SE is turned on (#
252rYES), the image displayed on the monitor on the TV is erased (#253), and the process returns to #203. If the erase switch SE is not turned on (NO in #252), the process directly returns to #203.

Steps from #235 onwards are a routine for determining access buttons ST and SW when the program is not in the movie mode, that is, when printing or TV playback is not in progress. When access button ST is turned on (YES in #235)
S), switch the photographic lens 102 to the telephoto side (#236
>, when the access button SW is turned on (YES at 9237)
), switch the ill shadow lens 102 to the wide side (#2
38). 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, so after resuming the charging operation that had been interrupted in the uncharged state (#240), the system returned and the uncharged flag was set to °゛0''.
If so, just return.
