Abstract

PURPOSE:To improve the universal applicability of a picture system by applying a component process and a compression process to a photographed picture to store this picture into an IC card and at the same time applying the modulation and the conversion of the signal accordant with each reproducer to the output of the IC card. CONSTITUTION:When the exposure is through with a CCD 401, the picture data fetched by the CCD 401 are sent to an internal memory 405 after undergoing the A/D conversion via an A/D converter 404. Then the picture data of the memory 405 are converted into the component signals together with a compression process and stored again into the memory 405. Then the picture data of the memory 405 are compressed and transferred to an attachable/detachable IC card 2. The card 2 can be loaded into and unloaded out of plural types of reproducers. When the card 2 is loaded to a reproducer, the output signal of the card 2 is expanded by an expanding circuit and converted into a signal coincident with the reproducer. Then this converted signal is outputted.

In FIG. 4, a CCD 401 is a solid-state image sensor equipped with an electronic shutter function as described above, and has R, G, and B stripe filters. COD-TG4
02 is for supplying control signals and clocks to each circuit in this block, and is used to generate a shutter operation control signal for the CCD 401 and a clock for driving image signal reading.
Clock generation to DS403, A/D converter 404
It generates a clock to the address controller 406 and a clock to the address controller 406. The CDS 403 performs sampling for double correlation on the output image signal of the CCD 401. A/D converter 404 is CCD 401
This converts analog output image signals into digital data. In this embodiment, an 8-bit A/D converter 404 is used, but an appropriate number of bits can be selected depending on the required image quality. The internal memory 405 has a short access time, for example, SR.
AM is used to take in serial data from the CCD 401 and save image data. This internal memory 4
05 has a capacity that can store at least one frame of photographed imagesii! In addition to the i-image area, there is a work area that serves as a work during image processing.

Further, the internal memory 405 also stores the results of data compression processing performed by the processor 407.

The address controller 406 receives the clock from the COD-TG 402 when taking in data from the CCD 401, and serially outputs the stored address signal of the internal memory 405, and also outputs the I/O output and address signal output from the processor 407 for processing. Decode and internal memory 405
Outputs the address signal to the IC, and further outputs the processing result data to the IC
The serial clock is read out at a low speed in order to write to an external recording medium such as a card 2. The table ROM 408 has a white balance (hereinafter referred to as WB) which will be described later.
Coefficient data for WB when performing corrections (referred to as ) and coefficient data for γ correction when performing color conversion for printers and TVs are written in advance. processor 4
07 performs each digital signal processing shown in FIG. 7 on the Ml data. The image data in the internal memory 405 is stored in the format shown in FIG.
, B is subjected to further compression processing such as WB processing and γ correction processing, and then written to the same address again.

The J3 and We processing uses a table ROM 40 in which conversion coefficients predetermined for color temperature information from the WB sensor 412 are stored.
8, and the γ correction process further converts the color-converted data via a table ROM 408 in which predetermined conversion coefficients are stored. In addition, compression processing can be performed, for example, by converting the original data to lit degree Y.
Separate the signal and color difference C (U, V) signal, compress it to 2/3, and then take the difference from the previous value for each Y, tJ, V and compress it to 1/2.
This is the DYtJV compression method for CD-1 shown in Table 1 above, which compresses the data to 1/3 as a whole.

A buffer 409 is interposed between the internal memory 405 and the IC card 2, and is used to temporarily store output image data from the internal memory 405. address controller 410
outputs the stored contents of the buffer 409 and generates a subsequent write address signal for inputting into the JC card 2.

Gate 411 is internal memory 405 or IC card 2
This function switches the connection between the CPU 3 and the processor 407, and connects the internal memory 405 and the IC card 2.
Switched by 01! ilJ all will be done.

Note that 413 is a device that converts the analog signal of the W8 sensor 412 into digital, and 210 is an internal battery of the IC card 2.

The operation of the above block configuration will now be described. C.P.
When the start switch SR is turned on in the photographing mode, the U 301 outputs a start signal to the COD-TG 402 and drives the photometry section 303 to perform photometry. The exposure control wD unit 306 controls the aperture based on the aperture value AvlC obtained from the photometry result, and further outputs the shutter control Shintan to the COD-TG 402 according to the exposure time Tv to
Expose the CD 401.

Upon completion of the exposure, the CPLI 301 switches the address controller 406 to output a serial signal and outputs a read permission signal to the COD-TG 402. As a result, the image data captured in the COD 401 is transferred to the internal memory 405. After transfer, CPU
301 connects the address controller 406 to the processor 40
7 side and communicate, and as detailed in FIG. 7, the image data is WB51! It outputs a command signal to perform compression processing, γ correction processing, etc., as well as compression processing. The image data subjected to each process is then stored in the internal memory 405 again.

On the other hand, if the IC card 2 can store data, the CPU 301
switches the gate 411 to connect the internal memory 4o5 and the IC card 2, and also connects the address controller 40.
6, 410 to output an address signal. This results in
Image data in internal memory 405 is transferred into IC card 2 via puff 7409.

Next, a block diagram of the printer section will be explained with reference to FIG.

The address controller 414 transfers compressed image data that has been subjected to various processes in the IC card 2 to a predetermined position in the processing work memory 416 in response to instructions from the processor 415 . Note that the above-mentioned predetermined means, for example, that data is stored for each row of the memory. Further, the address controller 414 decodes the address signal from the processor 415 and outputs the address signal to the work memory 416 when processing each signal.

The work memory 416 has a short access time, for example, SR.
AM is used for importing compressed data in the IC card 2, temporarily storing data, and saving processing results. The table ROM 417 is pre-written with γ correction coefficient data for converting image data for a TV into image data for a printer, and bitmap data for area gradation, which will be described later, in order to apply shading to pixels to be printed. ing.

The processor 415 demodulates the compressed data in the IC card 2, that is, expands it, converts the data for printer use, and performs the γ correction and area gradation using the table ROM 4''17.In other words, it expands the compressed data. A luminance Y signal and a color difference C signal, which will be described later, are generated, and a complementary color signal matching the color of the printer's ink is created from these signals.

Then, γ correction according to the printer is performed from this complementary color signal.

Furthermore, area gradation is performed for each color of each pixel using the pit map in the table ROM 4 1 7, and the result is written into the line sequential memory 418 to create data for each line with a width of 4 dots. Every time the above process finishes for one line,
Processor 415 outputs an end signal to CPU 301. In addition, in the case of the aforementioned CD-I system, compressed data decompression processing is performed by calculating the true difference based on the data on C card 2 and adding this difference data to the previous and adjacent value. AD, which will be described later.
In the case of the CT method, the data in the IC input code 2 is reproduced into the original data by performing an inverse transformation of the transformation performed during compression. The γ correction process converts image data created for a TV into image data for a printer using a table ROM. Furthermore, area gradation converts the color intensity of each pixel into the number of printed dots out of 16 dots consisting of 4 bits x 4 bits.

Then, these 4 bits×4 bits are sequentially taken into the line sequential memory 418 as one unit (one pixel).

The line sequential memory 418 has 4 bits for each pixel x
It stores one line of 4-bit data and outputs it to the buffer 7419 of the printer head 420 as data for one line (number of horizontal pixels x 4). The head 420 receives the outputs from the line sequential memory 418 and the buffer 419 and is heated to thermally transfer ink to paper.

The operation of the above block diagram will be explained.

When the CPtJ 301 detects a print start command while in the print mode, a print operation is started. When printing an image stored in the IC card 2, compressed signal data of the image to be printed is transferred from the IC card 2 to a predetermined position in the work memory 416 by the address controller 414. On the other hand, when directly printing the image in the internal memory 405,
A frame page in which an image to be printed is stored in internal memory 405 is selected by address controller 406 and taken into work memory 416 via gate 414 and processor 415.

Next, the CPU 301 instructs the processor 415 to perform signal processing for printing.

The processor 415 receives instructions from the CPU 301,
Read image data from the work memory 416 and display Cy (cyan), Ye (yellow), Ma (magenta) and Bk (black).
The above-described processing is performed in the order of the ink colors. CPU3.01
When detecting the end of the processing for one line, it controls the line sequential memory 418 and head 420 to print the one line. Each time the printing operation for one line is completed, the head 420 is moved one line in the direction of the arrow in FIG. 2(B) to prepare for printing the next line. In this way, the printing process of one frame of image for one color is completed. When the printing process for this one color Cy (cyan) is completed, the same printing process as above is repeated in the order of Ye (yellow), rl (? The printing process for the images is completed.

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.

FIG. 6 is a block diagram of TV playback, and an address controller 421 transfers compressed image data in the IC card 2 to a predetermined position in a video output memory 423 in accordance with a command from a processor 422. In addition, the above-mentioned predetermined
For example, it means storing data in each row of memory. Further, during signal processing, the address controller 421 decodes the address signal from the processor 422 and outputs an address signal to the video output memory 423, and when outputting a composite signal from the video output memory 423, Generates read serial address and clock for D/A converter 424. The video output memory 423 is a memory with a short access time, such as an SRAM, or an IC.
It is used to take in compressed image data in the card 2, temporarily store processed data during signal processing, and store the NTSC video signal that is the processing result.

The processor 422 decompresses compressed image data.
At that time, the luminance Y and color difference C signals are encoded.
and creates an NTSG composite signal.

This expansion process is performed in the same manner as described above. Also, the above encoding is done by modulating the color difference C signal using subcarriers! ! Add it once to the Y signal. D
The /A converter 424 decodes the NTSG composite Shintan into an analog TV signal. In addition,
The 75Ω driver 425 is provided for matching with the TV.

Regarding the above block diagram, the operation at the time of TV output will be explained.

CPt. When the l301 detects that the TV playback mode is entered, the playback operation by the TV is started.

The image stored in IC card 2 is sent to TV output terminal 1.
13, compressed image data to be output to the TV is transferred from the IC card 2 to a predetermined position in the video output memory 423 by the address controller 421. On the other hand, when the image in the internal memory 405 is to be played back on TV, the address controllers 406 and 421 select the frame page in which the image to be played on TV in the internal memory 405 is stored, and and is taken into the video output memory 423. Next, the CPU 301 enables the processor 422 and the address controller 421 to communicate with each other, and instructs the processor 422 to perform signal processing for TV reproduction.

Upon receiving the command from the CPtJ 301, the processor 422 reads the image data line by line from the video output memory 423, performs each process described below, and transfers the resulting digital NTSC Shintan back to the video output memory 423. S
Get into it. 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 writing to the video output memory 423, so that the image of one frame is stored in the video output memory 423. do. Then, when the processing for one frame is completed, the processor 422
A termination signal is output to 301. When the CPU 301 detects the end signal, the address controller 421 is

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

FIG. 7 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 a semi-white image is captured with light of the set color temperature using the color temperature coefficient determined by the color temperature information from the colorimetric systems 412 and 413 described above, the same signal This is to correct the level. This WB correction is performed 256 times (76

Next, in #12, γ correction is performed on the G signal and the WB-corrected R1B signal. This γ correction is also performed sequentially for one row in the column (horizontal) direction 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,

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 adding the low frequency brightness signal obtained in #15 and #16 and the Takagi brightness signal in terms of frequency (#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 played back on a TV, a burst signal and horizontal and vertical signals are added to the entire image and converted to a standard television signal such as NTSC Shintan (# 20~#22).

Next, FIG. 9(B) shows a state in which the movable part 101a is pulled out, and a printing operation is performed by bringing the thermal head 420 into contact with and scanning the transfer ink film 201. In this case, the supply member 221 remains within the movable portion 101a, but the thermal head 420 scans the print frame 202 shown in FIG. 2 in the direction of the arrow. This scan is 4
When the process is repeated twice, that is, for four colors, the photographed image is reproduced as a print using the composite color.

Next, FIG. 11 is a block diagram for explaining the configuration and operation of the printing section.

CPtJ301 controls the operation of this block as a whole. Reference numeral 431 denotes a print data creation unit comprising the aforementioned processor 415, line sequential memory 418, and the like. As described above, the buffer 419 converts the parallel data of the number of pits for one row supplied from the line sequential memory 418 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 420 using the output from the buffer 419.

The mechanism control circuit 433 controls each mechanism shown in FIG. 9 based on instructions from the CPLJ 301.
A head driving pulse motor 434 that drives the thermal head 420 in the scanning direction, a transfer ink film winding motor 435 that drives the transfer ink film 2010 winding 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 drives the thermal head 420 from one line of dot data supplied from the buffer 7419 based on the print command signal from the CPLJ 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 420 one line above the print frame 202 in the direction of the arrow shown in FIG. By alternately repeating printing with the Cy color and moving the thermal head 420, the first color printing with the Cy color is completed. After that, the CPIJ 301 uses the head drive pulse motor 434 to return the thermal head 420 to the reference position, that is, to the first line, and the transfer ink film winding motor 435 to return the thermal head 420 to the transfer ink film 2.
04 is driven to take up one color, and the Ye color is set.

Then, as described above, printing in Ye color and movement of the thermal head 420 are repeated alternately to complete printing in Ye color. Thereafter, similar procedures are performed for the MQ color and the Bk color, and in this way, the print reproduction of the image using the composite color is completed.

In addition, instead of the above printing method, as mentioned above, 1
Cy for each row. Ye, M.O. Each color of Bk may be printed.

Figure 12 shows the display a! 1106 is a block diagram when displaying on a monitor. FIG.

Note that in the figure, the same numbers as in FIG. 6 indicate the same items. The character output memory 440 is, for example, a RAM or the like, into which each character data sent from the CPtJ 301, such as the frame number displayed together with the image on the display unit 106, printing in progress, printing completion, etc., is stored. Further, instead of the RAM, a character generator that outputs predetermined character data in response to an instruction signal from the CPU 301 can also be used.

The synthesizing section 441 is for composing one screen by synthesizing the video output h and the 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.

Since the monitor display on the display unit 106 is performed during print operation or TV playback, each 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. The display 8I3106 stored image is played back.

First, when reproducing an image, as explained in Fig. 6,
Image data processed for TV output is stored in the video output memory 423. This image data can be accessed using the access button S.
This is the one stored in the frame number in the IC memory 2 or 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 CPU 301 is processed within processor 422 and stored in character output memory 440. and,
The character data in the character output memory 440 and the image data in the video output memory 423 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 composite data is D/
The signal is led to the display @@442 via the A converter 424 and displayed. When the start switch SR is turned on after the image is displayed on the monitor as described above, 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 next with a focus on the photographing operation based on the flowcharts of FIGS. 13 to 17.

The operation of this camera 1 is controlled by a program in a ROM (not shown) connected to the CPU 30'1 and the CPU 301.

When power is connected to camera 1, START in Figure 13
Run the routine.

That is, first, it is determined whether the main switch SM is turned on (#101). Main switch SM
If it is off (No in #101), go to #102, reset the flag, and display all1 06
When the display is displayed, turn off this display (#1
03), return to #101 again and wait for main switch SM to be turned on. Then, when the main switch SM is turned on (YES in #101), or if it is already in the on state when the above power supply is installed, an intrusion interrupt (IN
T) is possible in the state Lr (#1 04), #1 0
Proceed to step 5.

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), the process returns to #101 and repeats the routine of #101 to #104. on the other hand,
When the start switch SR is pressed (#1 05t'YES
), CCD40117) Turn on the power (#106)
．． That is, the power supply unit 307 is connected to the CPU 30 shown in FIG.
In response to the signal @<<P>> from 1, the high voltage VH is supplied to the COD as a power supply voltage. At the same time as this power supply starts, C
The instruction signal for initializing the CD401 is COD-TG4.
02, and the residual charge of the CCD 401 is erased (#107). Next, the photometry unit 303 performs photometry and calculates the exposure time T V % aperture value Av (#
108). Also, it is determined from the photometry results whether the subject is low ta or not (#109), and if it is determined that the subject is low brightness (YES in #109), the flash firing timing is first set to perform flash photography. Calculation is performed based on the photometric value (#111). Next, the flash unit 305
Determine whether the required charge has already been charged to the charge storage capacitor in the
NO in #112), sets the uncharged flag to “1” and starts charging (#113, #114), and when charging is completed (#114).
112: YES), proceed to #115. In #115, charging is stopped after confirming the completion of charging, and in #116 it is determined whether the unfilled flag is "1n".
'' (YES in #116), the unfilled flag is set to "0" in #117 and the process waits until the start switch SR is turned off (#118).

Then, when the start switch SR turns off (#118
If YES>, the process returns to #101 and a so-called release lock is performed. On the other hand, if the unfilled flag is "0" in #116, the process moves to #119 and the subroutine of exposure control 2 shown in FIG. 16 is executed.

In FIG. 16, first, INT is prohibited in #401, and the exposure time T v s aperture (i
Output a A v 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 CCD-TG 402 according to the exposure time Tv to expose the CCD 401. When the CPtJ 301 receives a signal from the exposure control unit 306 indicating that the release has started (exposure start) (9403), the CPtJ 301 performs the above #11
CP based on the flash emission timing determined in step 1.
Start the timer in U301 (#404). The flash is emitted at a timing after a predetermined period of time has elapsed from the start of exposure of the CCD 401. Next, the CPU 301 determines whether a release completion signal has been input from the exposure control unit 306 (#405).
. This determination is made because the exposure time Tv is
(For example, if the subject brightness suddenly increases during the counting operation of the flash timer, the exposure control unit 3
6 may output a release completion signal. That is, when the exposure control section 306 outputs a release completion signal before the flash emission timing (No. #405 in #406), the exposure operation is ended without emitting the flash. On the other hand, if the flash emission timing is reached before the release is completed (#406
YES], the flash is emitted and a release completion signal is output to the exposure control unit 306 (#407, #
408), terminating the exposure operation.

When this exposure operation is completed, it is determined in #409 whether the card flag is "1" or not. If it is "1" (YES in #409), the image signal captured by the CCD 401 is transferred to the installed IC. Controls writing to card 2 (#411
), if it is “0”, the image signal captured by the CCD 401 is controlled to be written into the internal memory 405 of the camera 1 (
#410). At this time, when the capacity of the internal memory 405 is saturated (YES in #416), a warning is given by display or voice (#417). After writing the image signal to the IC card 2, it is determined whether the capacity of the IC card 2 is saturated as described above, and if the capacity is saturated,
ES), the card flag is set to "0" in #413, and a warning is issued in #414. Note that the address of the internal memory 405 can be set to be continuous with the address of the IC card 2, and by doing so,
The system not only informs the photographer that the capacity of the card 2 has been saturated, but also allows future image signals to be stored in the internal memory instead of the IC card 2.

When the above processing is completed, in step #415, INT is set to a valid level and the process returns.

On the other hand, in the flowchart of FIG. 13, 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. 15 is executed (#110). In FIG. 15, INT is first inhibited in #301, and the exposure time T V s aperture fil A v obtained from the photometry a calculation is used as the exposure control unit 3.
06 (#302>) The exposure control unit 306 drives the aperture of the camera 1 based on these data, and outputs a shutter control signal to the COD-TG 402 according to the exposure time Tv to control the exposure of the CCD 401. When the CPU 301 receives a signal indicating that the release has started (exposure has started) from the exposure control unit 306 (#303), it starts a timer for measuring the limit time for manual photography (#304). This camera shake limit time indicates the maximum exposure time for proper shooting without camera shake, which becomes a problem when a relatively long exposure time without flash firing is required.After starting the above-mentioned timer, the above-mentioned As in the case of flash emission, it is determined whether a release completion signal is output from the exposure control unit 306 during the counting operation of the timer (#305). When the time TvlC is reached, the dew ratio control unit 306 outputs a release completion signal (YES in #305) and ends the exposure operation.On the other hand, if the timer count completes before the release is completed (#306) YES>, the CPU 30''l forcibly outputs a 1F ivy close signal to the exposure control plate unit 306 (#307), assuming that the camera shake limit time has been reached, and ends the exposure operation.

When this exposure operation is completed, in the same way as the processing in #409 to #417 in the exposure control tl02 routine, it is determined in #308 whether the card flag is "1", and if it is '1' (YES in #308). , controls the writing of the image signal taken into the COD 401 to the installed IC card 2 (#310),
The captured image signal is stored in the internal memory 405 of camera 1.
(#309). At this time, if the capacity of the internal memory is saturated (YES in #315), a warning is given by display or voice (#316). After writing the image signal to the IC card 2, the IC card 2
Determine whether the capacity of the card is saturated, and if the capacity is saturated (YES in #311), set the card flag to “O” in #312.
In addition to setting it to N, a warning is issued in #313. When the above processing is completed, INT is enabled in #314 and the process returns.

Returning again to the flowchart in FIG. 13, the above #11
When the exposure control subroutine in step 0 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 shooting of the frame is completed and the memory capacity of the IC card 2 and internal memory 405 is saturated (YES in #121), a warning is displayed or audible in #122 to call the photographer's attention. .

No warning will be given if recording is possible.

Then, the process moves to #123 and waits until the start switch SR is turned off, and when the start switch SR is turned off (
#1 23: YES), the CPU 301 outputs a signal (P) to turn off the power to the CCD 401 and ends the shooting of one frame <<#124>. , After the above processing, it is determined whether the flash has been fully charged for the next projection (#125>. If charging has not been completed (No in #125), it is determined that the flash is not fully charged. Set the complete flag to “1′”
' and start charging to complete charging (#
126, #127). On the other hand, if charging is completed (#
125: YES), set the unfilled flag to ``0'' and stop charging. (#128, #1 29). After this, return to #101 again and repeat the operations from #101 to #129 above. .

Next, from #1o4 onwards, where INT is enabled, the first
This will be explained using flowchart 1 in FIG. This INT occurs when the switch SC detects the presence or absence of the IC card 2, the switch SP detects transition to print operation, the switch SV instructs TV playback, and either the access button ST or SW is turned on.

When this INT occurs, the unfilled flag is set in #201 as ``
1", and if it is "1", it is assumed that INT has occurred while charging the charge storage capacitor, and #20
Charging is temporarily stopped at step 2, and if the value is "0", step #202 is skipped, and step #203 determines whether the switch SG has been turned on from off. If the switch SC remains off (NO in #203), it is determined that the IC card 2 is not installed, and the card flag is set to "0" and a display indicating that the IC card is not installed is displayed (# 205
, #206).

On the other hand, when switch SC is turned on (YES in #203)
), the subroutine for installing the IC card in #204 is executed.

FIG. 17 is a flowchart explaining this subroutine. That is, first, in #501, a memory map indicating the storage state of images in the IC card 2 is read out,
In #502, it is determined whether the storage capacity is saturated, that is, whether images can be stored. If image storage is possible (No in #502), set the card flag to “1” and display that an IC card is present (#
503, #504), if the storage capacity is already saturated (
YES in #502), turns on the card flag and issues a warning (#505, #506), and returns.

Returning to FIG. 14, next, it is determined whether the switch SP has been turned on from the tip. When the switch SP is turned on (YES in #207), it is determined that the movable part 101a has been pulled out and the printing operation has started, and the process proceeds to #208.
On the other hand, the switch SP remains in the 7 (7) position. ! = (#
207: NO), proceed to #229. In #208, 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 (#209). Access button ST
If it is turned on (YES in #209), the process moves to #210, and if the access button ST is turned off, remains on, or is turned off from on (NO in #209), the process moves to #215.

At #210, 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 controller 421 changes the frame number to the corresponding frame number in order to reproduce the image corresponding to the frame number. The corresponding address data is output (#211). After allowing time for the above processing in #212, image information corresponding to the current frame number is displayed on the display unit 106 (#213). Then, the process returns to #209, and the process of incrementing the frame number by 1 each time the access button ST is pressed and displaying the image corresponding to the frame number on the display unit 106 is repeated. On the other hand, #2
In step 15, it is determined whether the access button ST is on or not. If it is on (YES in #215), the process returns to #209, and if it is off (No in #215), the process moves to #216.

Next, when the access button SW is turned on instead of the access button ST (YES in #216), the process moves to #217, and when the access button SW is turned off or remains on, or is turned off from on (# (NO in 216), the process moves to #222.

In #217, 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 controller 421 changes the frame number to that frame number in order to play back the image corresponding to this frame number. Output the corresponding address data (#218). After waiting for the above processing time in #219, the image information corresponding to the current frame number is displayed on the display unit 106 (#220). Then, the process returns to #216, and the process of decrementing the frame number by 1 each time the access button SW is pressed and displaying the image corresponding to the frame number on the display unit 106 is repeated. On the other hand, #2
In step 22, it is determined whether the access button SW is on, and if it is on (YES in #222), the process returns to #216, and if it is off (No in #222), the process moves to #250.

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 from the IC card 2 or the internal memory 405 (#251), and the process moves to #203. on the other hand,
If the erase memory SE is not turned on (No in #250)
), the process moves to #223 and it is determined whether the start switch SR has been turned on.

If the start switch SR is not turned on (NO in #223)
), 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 #223), the CPU 301 outputs a print command signal to the processor in the block 302 in order to proceed to the print operation (#224). The processor receives the above signal and causes the printer section to start a printing operation. On the other hand, the CPU 301 displays on the display unit 106 that printing is in progress, and performs the ill'to printing operation described above (#225, #226).

At #227, the process waits for the printing to be completed, and when the print completion signal is not output (YES at #227), the display indicating the print completion is turned on. By the above operation, 1
Printing of the frame is completed, and the process returns to #203.

On the other hand, if switch SP is not turned on in #207,
It is determined that no printing operation will be performed and the process moves to #229. That is, in #229, it is determined whether the TV playback switch S is turned on. TV playback switch S■
is off (No in #229), it is determined that the TV will not display the playback and the process moves to #241.
When the V regeneration switch SV is turned on (YE in #229)
S) Displays a playback mode indicating that playback and display will be performed on the TV (#230>.

In this playback mode, it is then determined whether the access button ST or SW is pressed (#231,
#236). When the access button ST is turned on (#231
(Yes), the frame number is increased by 1 and displayed, and the address controller 421 selects this piece ffij3.
Address data corresponding to the frame number is output in order to reproduce the image corresponding to the frame number (#232, #233). Next, as described above, the image information corresponding to the current frame number is displayed on the TV monitor (#234). And #231
Returning to , the process of incrementing the frame number by 1 each time the access button ST is pressed and displaying the image corresponding to the frame number on the TV is repeated. On the other hand, in #235, it is determined whether the access button ST is on, and if it is on (#
235 is YES), return to #231, and if it is off (#
235: No), move to #236.

Next, when the access button SW is turned on instead of the access button ST (YES in #236), the process moves to #237. On the other hand, if the access button SW is turned off or remains on, or is turned off from on (No in #236), move to #240.

In #237, it is determined that the access button SW has been pressed, and the frame number is incremented by 1 and displayed, and at the same time, the address controller 421 inputs the address data corresponding to the frame number in order to reproduce the image corresponding to this frame number. (#238>. Next, as described above, the image information corresponding to the current piece N@ is displayed on the TV monitor (#239)
. Then, the process returns to #236, and the process of decrementing the frame number by 1 each time the access I] sw is pressed and displaying the image corresponding to the frame number on the TV is repeated.

On the other hand, in #240, it is determined whether the access button SW is on, and if it is on (YES in #240), #
Return to 236 and if it is off (No in #240>, #2
52.

In #252, it is determined whether the erase switch SE is turned on. When this erase switch SE is turned on (#
252: YES), erase the image displayed on the TV monitor from the IC card 2 or internal memory 405 (#253), return to #203, and if the erase memory SE is not turned on (#252: No) , as is #2
Return to 03.

Steps after #241 are a routine for determining access buttons ST and SW when photographing, that is, when not printing or playing on TV. When access button ST is turned on (YES in #241)
S), switch the projection lens 102 to the telephoto side (#242
), when the access button SW is turned on (YES in #243)
), switch the II shadow lens 102 to the wide side (#24
4). When access buttons ST and SW are both off, lens switching is not performed. Then, at the end of this INT, it is determined whether the unfilled flag is "1"(#24
5). If the incomplete charging flag is ゛゜1, the I
Since NT has occurred, the charging operation that was interrupted in the uncharged state is restarted (#246>), and then returns. If the uncharged flag is "0", the process returns directly.

Next, FIGS. 18 to 32 show the data from the IC card 2 to the CRT.
7 (hereinafter referred to as TV7), from IC card 2 to CD
- To ROM4, from IC card 2 to TV phone 11 and I
The blocks that guide stored image data from the C card 2 to the FAX 10 are shown.

Note that in Figures 18 to 21, the stored image data is NTSC.
In the case of a signal, FIGS. 22 to 25 show that the stored image data is R.
In the case of a GB signal, Figs. 26 to 29 show cases in which the stored image data is a color difference signal, and Figs. 30 and 31 show cases in which the stored image data is stored using the ADCT compression method instead of the CD-I compression method. In this case, FIG. 32 is a diagram showing a case where a video telephone and a FAX are integrated.

First, FIG. 18 is a block diagram for reproducing image data stored in the IC card 2 on the TV 7. In the figure, 50A is a conversion unit having an expander 501A, which adds a previous value to the differentially compressed image data to restore the original image data.

The image data in the IC card 2 is stored in the form of differentially compressed NTSC signals. The differentially compressed data output from the IC card 2 is returned to the original image data by the decompressor 501A and output.

Since this output signal has been converted into an NTSC signal, it is directly output to the TV 7 and reproduced.

FIG. 19 is a block diagram for transferring image data stored in the IC card 2 to the CD-ROM 4. Reference numeral 60A denotes a converting unit that restores the differentially compressed image data to the original image data and performs CD-I processing, and includes an expander 601A, a color difference modification circuit 602A, and a differential compression circuit 603A.

The image data in the IC card 2 is stored in the form of differentially compressed NTSC signals. The differentially compressed data output from the IC card 2 is returned to the original image data by the decompressor 701A. Since the image data is an NTSC signal, it can be directly input for TV use, but it is output to the TV phone 11 after being subjected to a predetermined thinning process by the thinning circuit 702A in consideration of the transmission capacity of the telephone line. In addition,
When using ISDN (digital communication network) as the telephone line, the thinning circuit 702A may be removed.

In addition to controlling the entire block and managing the flow of image information, the MPU 808A performs general control such as communication control and network control.The RGB conversion circuit 802A converts the expanded original image data into RGB data. The AOCT compression circuit 803A converts the 180/
A type of transform coding based on the JTC1/SC2/WG8 and N800 standards, which extracts multiple signals from low frequencies to high frequencies by orthogonally transforming the image signal, and among these extracted signals, generally only the high frequency components Focusing on the fact that the correlation with Shintan Hara decreases, data is compressed by reducing the number of sampling bits for signals with higher frequency components, but since the signal is converted into frequency components, it is not limited to high frequency components. , it is also possible to reduce the number of sampling bits of a certain constant frequency component. Then, the screen is divided into blocks of an appropriate number of pixels, and the numerical string consisting of sample values is orthogonally transformed for each block. In other words, this ★
In the example, ADCT compression transform is performed by dividing the image signal into blocks of 8 x 8 pixels, and then performing two-dimensional DCT (Discret
e Cosine Transform ). Each transformed term becomes more independent (more unrelated) than the original sample value, thereby suppressing redundant information.

Memory 804A is used as a transmission buffer. The communication control unit 805A executes a predetermined facsimile transmission control procedure to transmit image data to the other party's station. The modem 806A modulates digital data so that a public telephone line, which is an analog network, can be used for transmission. In this embodiment, the modem 806A performs signal modulation to transmit an ADCT compressed signal onto a TV telephone line. Also, when using ISDN, a modem for that purpose is used. NCLJ807A is F when sending
This is for connecting AX10 to the public telephone line network.
The CU 810A is for connecting the FAX 10 to the public telephone line network during reception.

In FIG. 48, (a) is the menu mode as the initial screen. On the screen, the white area indicates the selected position of the cursor key. (a) When you select "Play" on the screen, a playback display is performed on the TV7. In other words, when you select "Play" and turn on (select) the enter key, (b) ii! i
A screen appears that indicates the type of recording medium on which the image to be reproduced, such as the i-side, is stored. Here, for example (b) lj
When "disc" is selected on the i-side, the album number corresponding to the recording block in the disc (compatible with CD-ROM 4) is displayed as shown in screen (C1). And (C1
>> When you select "Album 1" on the screen, a screen showing the playback display format such as (C2) picture card will appear, and if you press the enter key again, the recorded images of Album 1 will be displayed from within the recording area of the disc. One will be played. On the other hand, (b
) When "Card 1" is selected on the screen (c2), a screen showing the playback display mode of images stored in Card 1 or whether or not to search appears, as shown in page 1 of (c2). Each screen returns to the previous screen in sequence by turning on the return key. For example, the (c1) screen returns to the (b) 1m plane, and when the return key is pressed again, the screen returns to the (a) ii plane.

) The type of image transfer between multiple recording media is displayed as shown in the screen below. Here, if you select [Card 1 → Disk] on the (b) screen, ■c card 1 will appear as shown on the (C) screen.
The album number indicating the block that records the uniformity transferred from within is displayed. Then, when "Album 1" is selected on the (C) screen, the image transfer format is displayed.

Then, when you press the enter key on the <d> screen,
The am in the C card 2 is transferred and recorded in the album in the disc in the form of a standard screen. Note that, as described above, when the return key is turned on, the screen returns to the previous screen in sequence.

The form of the screen to be erased is displayed as shown in 1). On the other hand, when "disc" is selected on the screen (b), the album number to be deleted from the disc is displayed as shown on the screen (C2). Then, when "Album 1" is selected on the (c2) screen, the format of the screen to be deleted is displayed. Then, (d2) screen "WA quasi-screen" or "multi-V
When "Side II" is selected, the images in album 1 are deleted. On the other hand, when "Screen designation" is selected, a designation screen (not shown) is further displayed to allow individual image designation, and after playing back and confirming this image once, it is possible to erase the middle of the designated image.

Note that, as described above, when the return key is turned on, the screen returns to the previous screen sequentially.

FIG. 51 shows a case where "auxiliary function" is selected in the menu mode. When you select "Auxiliary Functions" on the (a) screen, the titles of "Data Entry" and other functions, which will be described later, are displayed as shown on the (b) screen. Note that, as described above, when the return key is turned on, the screen returns to the previous screen sequentially.

Now, in FIG. 41, the CD-ROM driver 3,
The determination is made using the remote controller 5 or the function keys on the keyboard 6. That is, if the cursor key is pressed (turned on) (YES in S41), the menu to be selected is changed in S42. For example, if you turn on the cursor key on the screen shown in Figure 48 (a), the white area will change to "Copy".
, and this "copy" becomes selectable. Furthermore, when the cursor key is turned on, the white area changes to "erase". If the cursor key is not pressed, it is determined in s43 whether the enter key has been turned on.

If the enter key is turned on, ``YES at s43'',
In S44, the process moves from the next menu or menu mode to screen mode. For example, when the enter key is pressed on the screen (a) in FIG. 48, the screen moves to the (b) screen, and when the enter key is further turned on, the screen moves to the (CI) screen. Also, the same figure (c2
>> When you press the enter key on the screen, the image data in the IC card 1 will be displayed on the TV 7 on a standard screen. If the enter key is not pressed, it is determined at 845 whether the clear key has been turned on. If the clear key is turned on (845t'YES), the process returns to the IIil menu screen in S46. For example, when the clear key is turned on in the screen shown in FIG. 48 (c1), the screen returns to the (b) screen, and when the clear key is turned on again, the screen returns to the (a) screen.

FIG. 42 shows the standard screen processing subroutine indicated by 834 above.

In this process as well, determination is made using the CD-ROM driver 3, the remote controller 5, or the function key 7 of the keyboard 6. That is, if the cursor key is pressed (turned on) (YES in S51), the image currently being played back on the TV 7 is changed to the next or previous image in 852. If the cursor key is not pressed, it is determined at 853 whether the enter key has been turned on. If the enter key is turned on (YES in S53), start or conversely stop the timer for automatically advancing the playback screen sequentially in step 854, and return to image advancing using the cursor keys.a.
If the enter key is not pressed, it is determined at 855 whether the clear key has been turned on. If the clear key is turned on (S55: YES), the process returns to the menu mode screen or multi-screen at 856. For example, when an image is being played back on the TV 7, if the clear key is turned on, the screen returns to the menu mode such as the screen shown in FIG. 48 (C2).

Also, if you are transitioning from multi-screen to standard screen,
Turn on the clear key to return to the multi screen again.

Here, the multi-screen will be explained using FIG. 52.

The multi-screen displays on the TV screen, for example, a display section D1 that reproduces 2o frames of images, and a display section D that displays the type of recording medium in which the reproduced images are stored, for example, "Card 1 →" as shown in the figure.
Display section D2 displayed below 1, the previous 20 frames of images,
Or "previous group" to select the next 20 frames of images.
, "It is composed of the display parts D3 and D4 of the next group. Also,
SF+ is a selection frame that can be moved between each image area within the display section D1 or each of the display sections D2 to D4 by operating the cursor keys. Then, when the enter key is turned on, the processing illustrated in FIGS. 43 and 44 is executed.

FIG. 43 shows the multi-screen mode subroutine indicated by 836 above.

In this process as well, determination is made using the CD-ROM driver 3, remote control 5, or function key of the keyboard 6. In other words, if the cursor key is pressed (YES in s61), the selection frame SF1 is moved vertically and horizontally in the multi-picture garden currently being played on the TV7 in 862, and the selected image or each display section D2 is moved. ~Change the selection of D4.If no cursor key is pressed, 88
In step 3, it is determined whether the enter key has been turned on.

If the enter key is turned on (YES in S63),
In S64, a subroutine for enter processing in the multi-screen mode (explained in FIG. 44) is executed. If the enter key is not pressed, it is determined in S65 whether the clear key has been turned on.

If the clear key is turned on (YES in S65), S
66 returns to the menu mode screen. For example, when a multi-image is being played back on the TV 7, if the clear key is turned on, the screen returns to the menu mode such as the screen shown in FIG. 48 (C2).

FIG. 44 shows a subroutine for enter processing in the multi-screen mode described above.

First, in 871, it is determined whether the display sections D3 and D4 shown in FIG. 52 are selected by the selection frame SF1.

Display section D3, if Da is selected (YES in S71)
S), 872 for images of 20 frames in the previous group or 20 frames in the next group.
Play the image for each frame.

If display parts D3 and D4 are not selected, $73
to determine whether it is in multi-screen playback mode.

If it is in the playback mode (YES in S73), the image selected in the selection frame SFt is displayed on the standard screen in 874 (42nd
Figure, S62). If it is not the reproduction mode, it is determined in step 875 whether the copy mode is present. If it is in the copy mode (YES in S75), the image selected in the selection frame SF1 is copied to the designated recording medium in 876, for example, "card→disc". If it is not the copy mode, it is determined in S77 whether the erase mode is selected. If it is in erase mode (YES in S77), S78
Delete the selected image.

FIG. 45 shows the data input processing subroutine indicated by 838 above.

In this process, discrimination is performed using the CD-ROM driver 3, the remote control 5, or the function key of the keyboard 6 and the character key 392 of the keyboard 6. In other words, when the cursor key is pressed (turned on), (S
(YES in S81), move the cursor display position in S82, and then turn on the enter key (YES in S83)
, 384 to register the input search data. on the other hand,
When the clear key is turned on (YES in S85), 88
Step 6 erases the search data at the cursor position. Next, if the character key is pressed (YES in S87), 888
Enter the search data at the cursor position. To input this data, use the character key 3 when recording on CD-ROM4.
92, the photographing location, date, and additional items are input as search headings for each album as a block. Also, you can re-enter the data after deletion.

FIG. 46 shows the image transfer subroutine shown in S4 above.

Once the display mode is set through the processes up to FIG. 45, the process moves to this image transfer subroutine. That is,
If you want to play the screen with 891 (YES in S91),
In S92, the image to be reproduced is transferred to the image memory 354 in preparation for image reproduction.

If the copy mode is selected (YES in S93), the image to be copied is written to the recording medium to be copied in S94.

Also, if you are in erase mode, select YES in S95), S9
In step 6, the target image is erased from the recording medium. When this image transfer process is completed, image creation process is executed next.

FIG. 47 shows the image creation subroutine shown in S5 above.

First, it is determined whether or not to display the menu mode.

To display the menu mode (3101: YES)
, 8102, the image processor 355 creates a menu screen. On the other hand, when playing in standard screen mode (3103: YES), the image memory 3
54 is played back. If reproduction is to be performed in the multi-screen mode (YES in S104), the image processor 355 performs a predetermined thinning process on the images in the image memory 354 in step 8105, and then creates a multi-screen. Also, if data input mode is selected (S
106't'YES), and in 8107, the image processor 355 creates a screen for data input. After each of these processes is executed, the process returns.

The screen data created through the processing from 82 to s5 in FIG.
and is played or displayed on TV7. Furthermore, after the processes of S7 and S8 described above are executed as necessary, the process returns to s2, and thereafter this process is sequentially repeated.

In this embodiment, a separate keyboard is used as a means for inputting search information, but it may be integrated with the CD-ROM driver 3.
