Abstract

PURPOSE:To secure the recording capacity and at the same time to facilitate the reproduction of a desired picture by enabling both a built-in memory and an externally attachable memory to fetch the photographed pictures and also to read and reproduce the picture data. CONSTITUTION:The picture data fetched into a CCD 401 are transferred to an internal memory 405 after the exposure of the CCD 401. Then a WB process and a gamma correction process are applied to the picture data by a command signal of a CPU 301. When these processes are through, the picture data are stored again in the memory 405. At the same time, the picture data in the memory 405 are transferred to an IC card 2 as long as these data can be stored in the card 2. When the capacity of the card 2 is saturated, the picture data are stored again into the memory 405. Then a gamma correction process is applied to the picture data stored in the card 2 and the memory 405 by a command of a processor 407 in accordance with a printer. Thus these picture data are printed by a head.

In FIG. 4, the CCD 401 is a solid-state m-image element 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
The address controller 406 generates clocks for the address controller 406 and the address controller 406. The CDS 403 performs sampling for double correlation on the output image signal of the CCD 401. The A/D converter 404 is CG()40
This converts the analog output image signal of No. 1 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 interval between accesses, e.g.
The RAM is used to take in serial data from the CCD 401 and store image data. This internal memory 405 has a work area which is used during ms processing in addition to an image area having a capacity capable of storing at least one frame's worth of shadow images.

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 write 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 ROM40B is 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 image 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.

Note that WB processing is performed using a table ROM 408 in which conversion coefficients predetermined for color temperature information from the WB sensor 412 are stored.
The γ correction process further converts the color-converted data via a table ROM 408 in which predetermined conversion coefficients are stored. In addition, the compression process, for example, separates the original data into a luminance Y signal and a color difference C (U, V) signal, compresses it to 2/3, and then calculates the difference from the previous value for each Y, LJ, V. The CD shown in Table 1 above, which is compressed to 1/2 and compressed to 1/3 as a whole.
This is the DYLIV compression method of I.

A buffer 409 is interposed between the internal memory 405 and the IC card 2, and temporarily stores output image data from the internal memory 405. address controller 410
outputs the contents stored in the buffer 409 and generates read and write address signals for writing to the IC 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.
Switching is controlled by 01.

Note that 413 is a device that converts the analog signal of the WB 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
When the start switch SR is turned on in the award mode, the P tJ 3.0 1 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 based on the aperture value Av obtained from the photometry result, and further controls the shutter control signal J3eCOD-TG4021 according to the exposure time Tv.
The C output LTCCD 401 is exposed.

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 COD-TG 402. As a result, the image data captured in the COD 401 is transferred to the internal memory 405. After transfer, CPL,
1301 connects the address controller 406 to the processor 4
07 side for communication, and outputs a command signal to perform WB processing, γ correction processing, etc., and further compression processing on the image data, as will be described in detail in FIG. 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
The image data in the internal memory 405 is transferred into the IC card 2 via the spreader 409.

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 during each signal processing described later.

The work memory 416 has a short access time, for example, SR.
In AM, it is used for importing compressed data in the IC card 2, temporarily storing data, and saving processing results. The table ROM 417 contains in advance γ correction coefficient data for converting image data for a TV into image data for a printer, and pit map data for area gradation, which will be described later, for applying shading to pixels to be printed. ing.

The processor 415 processes the compressed data II in the IC card 2.
In other words, the data is expanded and converted for printer use, and the table ROM 417 is used to perform the γ correction and area gradation. In other words, decompress the compressed data and
A color difference signal Y and a color difference C signal, which will be described later, are generated, and a complementary color signal matching the color of the ink of the printer is created from these signals. Then, from this complementary color signal q, γ correction is performed depending on the printer.

Further, for each color of each pixel, surface v4Wi toning is performed using the pit map in the table ROM 417, and the result is written to the line sequentialization 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 above-mentioned CD-1 system, compressed data decompression processing is performed by finding the true difference based on the data of IC power code 2, and adding this difference data to the previous adjacent value. This is reproduced in the data, and the AD
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
Data of 4 pits is stored for one line, and the data for one line is converted into data of <number of horizontal pixels x 4> and output to the buffer 7419 of the printer head 420. The head 420 receives the output 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 CPLJ 301 is in the print mode, the print operation is started when the CPLJ 301 detects a print start command. 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, the address controller 406
A frame (page) in which an image to be printed is stored is selected and taken into a work memory 416 via a gate 414 and a 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 the image data from the work memory 416 and display Cy (cyan), Ye (yellow), MO (magenta), and Bk (black).
The above-described processing is performed in the order of the ink colors. When the CPU 301 detects the end of the processing for one line, it controls the line sequential memory 418 and the 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), MO (magenta), and Bk (black), and as a result, the printing process for one frame is completed. The printing process for the image 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, in which an address controller 421 transfers compressed image data in the IC card 2 to a predetermined position in a video output memory 423 in response to instructions 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 the address signal to the video output memory 423, and furthermore, when outputting the composite signal from the video output memory 423, the address controller 421 decodes the address signal from the processor 422 and outputs the address signal to the video output memory 423. Generates 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.
to create an NTSC composite signal.

This expansion process is performed in the same manner as described above. Furthermore, in the encoding, the color difference C signal is modulated using subcarriers and added to the luminance Y signal. D/A
The converter 424 decodes the NTSC composite signal into an analog TV signal. In addition, 75
The Ω driver 425 is for matching with the TV.

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

When the CPU 301 detects that the TV playback mode has been entered, the playback operation by the TV is started.

Images stored in IC card 2 are sent to TV output terminal 1.
13, compressed image data to be output to the TV is transferred from the IC input 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 frame in which the image to be played on TV is stored in the internal memory 405 is selected by the address controllers 406 and 421, and Then, the CPtJ 301 enables the processor 422 and address controller 421 to communicate with each other, and instructs the processor 422 to perform signal processing for TV playback.

The processor 422 receives instructions from the CPU 301,
The image data is read line by line from the video output memory 423, various processes described below are performed, and the resulting digital NTSC signal is written into the video output memory 423 again. 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
An end signal is output at 01. When the CPtJ301 detects the above end signal, the address controller 421 is
Switching to SC output, this causes video output memory 42
3 outputs an NTSC composite signal, and operates the D/A converter 424 to output an analog TV signal.

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

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 colorimetry systems 412 and 413 described above, the signal level is the same. It is corrected so that it becomes . This WB correction is performed 256 times (76

At the same time, the levels of R, G, and B, which form point-sequential inertia levels in the frequency domain, are adjusted. This low range (#15)
Similarly to the above, the Takashiro (#16) processing is also performed sequentially for one row in the column (horizontal) direction in units of three RGB pixels.

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 7419.

The mechanical unit control circuit 433 controls each mechanical unit shown in FIG. 9 based on instructions from the CPU 301, and controls a head driving pulse motor 434 that drives the thermal head 420 in the scanning direction, and winds up the transfer ink film 201. A transfer ink film winding motor 435 that drives the 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 419 based on the print command signal from the CPIJ 301.
An IXI thermal 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. Thereafter, the CPU 301 causes the head driving pulse motor 434 to return the thermal head 420 to the reference position, that is, the first row, and causes 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. MQ. Each color of Bk may be printed.

FIG. 12 is a block diagram when a monitor display is performed on the display unit 106.

In addition, in the figure, the same number as the 6th number indicates the same thing. The character output memory 440 is, for example, a RAM, in which character data sent from the CPU 301, such as the frame number displayed together with the image on the display unit 106, printing in progress, printing complete, etc., are written. Further, instead of the RAM, a character generator that outputs predetermined character data in response to an instruction signal from the CPU 301 may be used.

? The composition section 441 is for composing one screen by combining the video output and the character output. The display @ 442 is a liquid crystal TV monitor having the display unit 106, for example, and 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. At this time, the image stored on the display unit 106 is not reproduced.

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 synthetic data is D/
The signal is led to the display device @442 via the A converter 424 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 next with a focus on the photographing operation based on the flowcharts of FIGS. 13 to 17.

The operation of this camera 1 is performed by the CPtJ301 and the CPU3.
It is controlled by a program in a ROM (not shown) connected to 01.

When the power supply is attached 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 and reset the flag, and if it is displayed on the display unit 106, turn off the display (#103).
, returns to #101 again and waits for the 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-mentioned m source is installed, the interrupt (INT> described later) is enabled (#104), and the process goes 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), the process returns to #101 and repeats the routine of #101 to #104. on the other hand,
When the start switch SR is pressed (YES in #105>

2, and the residual charge of the CCD 401 is erased (#107). Next, the photometry unit 303 performs photometry and calculates the exposure time Tv-=aperture value Av (#1
08). Also, it is determined from the photometry results whether the subject is at low i degrees or not (#109), and if it is determined that the subject is at low 11 degrees (YES at #109), the flash is first fired to take a flash photo. The timing is calculated based on the photometric value (#1 1 1). Next, it is determined whether the Ti load storage capacitor in the flash unit 305 has already been charged with the necessary charge, and if charging has not been completed (NO in #112), the uncharged flag is set to "1".
When charging is completed (YES at #112), the process proceeds to #115. In #115, confirm the completion of charging and stop charging.
In #116, it is determined whether the unfilled flag is "1n".

If the unfilled flag is “1” (YES in #116),
In #117, the unfilled flag is set to "0" and the system waits until the start switch SR is turned off (#118). Then, when the start switch SR is turned off (Y in #118)
ES), return to #101 and perform a so-called release lock. On the other hand, if the unfilled flag is “O” in #116,
Proceeding to #119, the exposure control 2 subroutine shown in FIG. 16 is executed.

In FIG. 16, first, INT is prohibited in #401, and the exposure time T v s aperture value A obtained from the photometric calculation is
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 COD-TG 402 according to the exposure time Tv to control the CC.
Perform D401 exposure. CPLJ301 is exposure control section 3
When a signal indicating that the release has started (exposure start) is input from 06 (#403), the CPU 301
The timer within is started (#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 IIJtllll 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 release completion signal is output. That is, before the flash emission timing, the exposure control unit 306
outputs the release completion signal (NO in #406).

, #408), the exposure operation is ended.

When this exposure operation is completed, it is determined in #409 whether the card flag is "1", and if it is "1n", (#409)
C'YES), CCD4011. : Controls writing of the captured image signal to the installed IC card 2 (
#411), if it is “0”, control is performed to write the image signal taken into the CCD 401 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, (
#412: YES), #413t' card flag is set to “0”
” and a warning is issued in #414. Note that the address of the internal memory 405 is the same as the address of the IC card 2.
By doing so, the photographer can be notified that the capacity of the IC card 2 has been saturated, and future image signals can be stored in the internal memory instead of the IC card 2. It is designed so that it can be included. When the above processing is completed, INT is enabled in #415 and the process returns.

01(7) Perform exposure. CPU301 is exposed lIII
When a signal indicating that the Ia section 306-B release has started (exposure start) is input (#303), a timer for measuring the limit time for hand photography is started (#304). This camera shake limit time indicates the maximum exposure time that 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 timer, it is determined whether a release completion signal has been output from the exposure control section 306 during the counting operation of the timer, as in the case of flash emission (#305). When the exposure time ITv is reached before the camera shake limit time elapses (No in #306), the exposure me section 306 outputs a release completion signal (#306).

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 all frames have been photographed and the storage 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. do.

No warning will be given if recording is possible.

Then, it moves to #123 and waits until the start switch SR is turned off, and when the start switch SR is turned off (
(YES in #123), the CPU 301 outputs a signal (P), turns off the power to the CCD 401, and ends the imaging for one frame (#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,
#1 27). On the other hand, if charging is completed (#125
(YES), sets the unfilled flag to “0” and stops charging. (#128, #129). After this,
Return to #101 again and repeat the operations from #101 to #129 above.

Next, the process executed when this INT occurs after #104 where I'NT is enabled will be explained with reference to the flowchart of FIG. This INT is activated when the switch SC detects the presence or absence of the IC power cord 2, the switch SP detects the transition to print operation, the switch S■ instructs TV playback, and the access button ST or SW is turned on.

When this INT occurs, the unfilled flag is set to “ in #201.
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 SC 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

Next, FIGS. 18 to 32 show the IC card 2 6k to C
These blocks respectively lead stored image data to RT7 (hereinafter referred to as TV7), from IC card 2 to CO-ROM 4, from IC card 2 to TV telephone 11, and from IC card 2 to FAx1o.

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 G [3 signals, Figures 26 to 29 show when the stored image data is a color difference signal, and Figures 30 and 31 show when the stored image data is compressed using ADCT instead of the CD-1 compression method. If it is stored, FIG. 32 is a diagram in which the video telephone and 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 LC 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 to 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-1 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 NTSG 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 NTSG 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 interrogation circuit 702A may be removed.

is a conversion unit that restores the differentially compressed image data to the original image data, performs RGB conversion, and further performs compression processing. ! I have an i803A.

The MPU 808A not only controls the entire block and manages the flow of image information, but also performs general control such as communication control and network control. The RGB conversion circuit 802A converts the expanded original image data into RGB color signals.

ADCT compression circuit 803A is 130/JTCI/SC2
/ A type of transform coding based on the WG8 and N800 standards, in which an image signal is orthogonally transformed to extract multiple signals from low frequencies to high frequencies, and among these extracted signals, the higher the frequency component, the higher the original signal. Focusing on the fact that the correlation between signals decreases, data is compressed by reducing the number of sampling bits for signals with higher frequency components. It is also possible to reduce the number of sampling bits of frequency components. 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. That is, in this example, ADCT
Compression conversion is performed by dividing the image signal into blocks of 8 x 8 pixels, and then using two-dimensional OCT (Discrete Cosin
e Transform). Each transformed term becomes more independent (more unrelated) than the original Itomoto value, thereby suppressing redundant information.

Memory 804A is used as transmission buffer 7. 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. Furthermore, when using ISDN, a modem for that purpose is used. NCu807A uses FAX when sending
10 to the public telephone line network.
810A is for connecting the FAX 10 to the public telephone line III network during reception. The modem 811A demodulates analog signals into digital data. As described above, the communication control section 812A executes a predetermined facsimile reception control procedure in order to transmit image data to the other station. Memory 813A is used as reception puff 7. The expansion circuit 814A is an ADC
Input image data that has been subjected to T-compression conversion is returned to the original image data by inverse conversion. Plotter 815A prints the received facsimile image.

Furthermore, image data transmission or printing processing is executed (87, 88), and the process returns to 82, and this procedure is repeated thereafter.

Each process will be explained below.

First, regarding the operation input processing (Fig. 37, 82), the third
This will be explained using the flowchart shown in FIG.

Function key 37L 3 using either the CD-ROM driver 3, remote control 5 or keyboard 6
Determine whether there is input by 81 or 391 (S
11). If there is an input (YES in S11), a function code indicating that there has been an input using a function key is set (812) and the process returns; conversely, if there is no input using a function key, a function code indicating that there has been an input using a function key is set (812).
Then, it is determined whether there is any input using the character keys on the keyboard 6. If the character key is strong enough (YES in S13), set a character code indicating that there was an input using the character key (8

Next, the display mode setting (Fig. 37, 83) will be explained with reference to the flowcharts of Figs. 39 to 45.

First, in FIG. 39, it is determined in S21 whether or not a function code is set. If it is set (YES at $21), a subroutine for function code processing shown at 822 (shown in FIG. 40) is executed. (described later). Conversely, if it is not set, S23

In this step 823, the character code is set (YES in S23), and if the data input mode is set (YES in S24), the subroutine for data input processing (described later in FIG. 45) is executed in 825. and return. On the other hand, even if the character code is set, if you are not in data input mode (S
If No in #25) or if neither code is set (No in #23 and #24), the process returns as is.

Next, FIG. 40 shows a subroutine for function processing indicated at 822 above.

At 831, it is determined whether the display screen of the TV 7 is in menu mode. If the menu mode is selected (YES in S31), the menu processing subroutine (41st
(described later in the figure) and return. If it is not the menu mode, it is determined in S33 whether the mode is the standard screen mode.

This standard screen mode refers to a mode in which one image is displayed on the screen of the TV 7. In standard screen mode (Y in S33)
ES), the standard screen processing subroutine (42nd
(described later in the figure) and return. If the mode is not the standard screen mode, it is determined in S35 whether the mode is the multi-screen mode.

This multi-screen mode refers to a mode in which the screen of the TV 7 is divided to display a plurality of images, 20 images in this embodiment as will be described later. In the case of multi-screen mode (S35
(YES), the process moves to S36, executes a subroutine for multi-screen processing (described later in FIG. 43), and returns. If it is not the multi-screen mode, it is determined in S37 whether it is the data input mode. In the case of data input mode (837rYES), execute the 838r data input processing subroutine and return. If the mode is not data input mode, the process returns directly.

FIG. 41 shows a subroutine of menu processing indicated by upper panel 832.

This subroutine will be explained below with reference to examples of menu screens shown in FIGS. 48 to 52.

First, I will explain about Figures 48 to 51.

In FIG. 48, (a) is the menu mode as the initial screen. The white area on the screen indicates the selected position of the cursor key. (a) If you select "1 playback on screen", playback will be displayed on the TV 7. That is, when the enter key is turned on (selected) in "Playback", a screen showing the type of recording medium in which the image to be played back is stored appears, as shown in screen (b). Here, for example, if you select "Disc" on screen (b), the disk (C) will appear as shown on screen (c1).
The album number corresponding to the recording block in "Compatible with D-ROM4" is displayed. Then, when you select "Album 1" on the (C1) screen, a screen showing the playback display format, etc. as shown on the (C2) screen will appear. If you press the enter key again here, you can select "Album 1" from within the recording area of the disc. The recorded image will be played back.On the other hand, if you select "Card 1" on the (b) screen, the card 1 will be played back as shown on the (c2) screen.
A screen will appear showing the playback display format of images stored in the memory or whether or not to search. Each screen returns to the previous screen in sequence by turning on the return key. For example, if the C1 screen returns to the (b) screen and you press the return key,
(a) Return to the screen.

FIG. 49 shows a case where "Coby" is selected in the menu mode. (a} When you select "Copy" on the screen, (b
) 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 image 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 in the state of the (d) screen, I
The images in the C-drive 2 are transferred to an album on the disc in the form of a standard screen and recorded. Note that, as described above, when the return key is turned on, the screen returns to the previous screen in sequence.

FIG. 50 shows a case where "erase" is selected in the menu mode. When "Erase" is selected on the screen (a), the type of recording medium to be erased is displayed as shown on the screen (b).

Here, if you select "Card 1" on the (b) 1i side, (
The form of the screen to be erased is displayed as shown in C1). On the other hand, if you select "Disc" on the (b) screen, (c2)
The album number that will be deleted from the disc will be displayed as shown on the screen. Then, on the (C2) screen, select “Album 1”
When you select , the format of the screen to be deleted will be displayed. Then, when the "standard screen" or "multi-screen" screen (d2) is selected, the images in album 1 are deleted.

On the other hand, if you select and translate "screen designation", a designation screen (not shown) is displayed, allowing you to designate individual images, and after playing back and confirming the images, you can erase each 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 the case where "auxiliary function" is selected in the menu t-do. When "Auxiliary Function" is selected on the (a) screen, titles of other functions such as "I-Data Manpower", 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 turned on (YES at S41), the menu to be selected is changed at S42. For example, Fig. 48(a)
When you turn on the cursor key on the screen, the white area moves to "Coby" and this "Copy" becomes selectable. Furthermore, when you turn on the cursor key, the white area moves to "erase". If the cursor key is not pressed, it is determined in S43 whether the enter key has been pressed. If the enter key is turned on (YES in S43), the process moves from the next menu or the menu mode to the screen mode in S44.

For example, if you press the enter key on the screen (a) in Figure 48, the screen will move to screen (b), and if you press the enter key again, the screen will move to (C1). Also, if you press the enter key on the screen (C2) in the same figure, the screen will move to screen (C1). Then, the image data in the IC card 1 is displayed on the TV 7 on a standard screen.If the enter key is not pressed, it is determined in S45 whether the clear key has been turned on.If the clear key has been turned on (S45 DeY
ES), and returns to the previous menu screen in S46. For example, if you turn on the clear key on the screen shown in Figure 48 (C1),
Return to the screen and press the clear key again to return to the (a) screen.

FIG. 42 shows a subroutine for the basic screen processing indicated by 834 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. That is, if the cursor key is pressed (turned on) (YES in S51), the image currently being played on the TV 7 is changed to the next or previous image in 852.If the cursor key is not pressed, Determine whether or not the enter key is turned on in S53. If the enter key is turned on, YES in S53), start or stop the timer for automatically advancing the playback screen in sequence in 854, and press the cursor key. Return to image forwarding.

. 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 (YES in S55), the process returns to the menu mode screen or multi-screen in 856. For example, TV
If the clear key is turned on while the image is being reproduced in step 7, 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 a display section D1 that reproduces images for, for example, 20 frames, 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.
, F-order group' display section 'D3 and D4. Furthermore, SFt is a selection frame that can be moved within each image area within the display section D1 or each of the display sections D2 to D4 by operating a cursor key. Then, when the enter key is turned on, the processing described later with reference to FIGS. 43 and 44 is executed.

FIG. 43 shows the subroutine of the multi-screen mode shown in S36 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. That is, if the cursor key is pressed (turned on) (YES in S61), the selection frame SFt is moved up, down, left and right in the multi-screen currently being played on the TV7 in 862, and the selected image or each display section is moved. Change the selection from 02 to D4. If no cursor key is pressed, 86
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.

If display sections D3 and D4 are 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 SF1 is displayed on the standard screen in 874 (42nd
Figure, S62). If it is not the reproduction mode, it is determined in S75 whether the copy mode is present. When in coby mode, select S75 (YES), -876 select SFt
Copy the selected image to the specified recording medium, for example, from "card to disc". If it is not the copy mode, it is determined in S77 whether the erase mode is selected. If you are in erase mode (YES in S77), 8
The selected image is deleted in step 78.

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
81 (YES), move the cursor display position in S82,
Next, when the enter key is turned on (YES at S83),
The search data input in step 884 is registered. On the other hand, when the clear key is turned on (S85: YES), the search data at the cursor position is erased at 886. Next, if the character key is pressed (YES in step S87), search data is input at the cursor position in step 888. To input this data, press the character key 392 when recording on CD-ROM4.
As a result, the shooting location, date, and additional information are input as search headings for each album as a block. Also,
You can re-enter the erased image.

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),
892, the image to be reproduced is transferred to the image memory 354 and prepared for image reproduction. In the case of copy mode (YES in S93), the image to be copied is transferred to the recording medium to be copied in S94. In addition, in the erase mode,
(YES at 95), and the target image is erased from the recording medium at 896. When this image transfer process is finished,
Next, the image creation process is executed.

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 (YES at 8101)
, 8102, the image processor 355 creates a menu screen. On the other hand, when playing in standard screen mode (YES in 8103), the image memory 3
54 is played back. If reproduction is to be performed in the multi-screen mode (YES in 8104), in 8105 the image processor 355 performs a predetermined thinning process on the images in the image memory 354, and then creates a multi-screen. Also, if data input mode is selected (8
106: YES), image processor 35 at S107
5 to create a screen for data input. After each of these processes is executed, the process returns.

The screen data created in the process from 82 to S5 in FIG.
and is played or displayed on T7. 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.

In the above explanation, TV, TV telephone, CD-ROM
In the reproduction using the Handycoby 12 shown in FIG. That is, the image stored in the IC card 2 is printed. The printing method (including signal processing) is the same as that explained in FIG.

Further, in this embodiment, a thermal transfer type is used as the printer method, but either a sublimation type or a melting type may be used, or a heat-sensitive coloring type may be used. Furthermore, it may be an inkjet or bubble jet method that uses a single color that does not require an ink film, or a plurality of colors as in this embodiment.

Furthermore, in this embodiment, a printer unit that does not have a recording paper and a recording paper feeding mechanism has been described, but
A built-in recording paper type may be used as shown in Japanese Patent No. 189785.

Further, in this embodiment, digital memories are used as the first memory and the second memory, but the present invention is not limited to this, and a floppy disk or an optical disk that can store analog data may be used.

Further, the content may be printed out using not only the built-in printer but also an external printer, and not limited to the external monitor TV but a TV provided inside the main body for reproduction.

〔Effect of the invention〕

As explained above, according to the present invention, the captured image itself can be imported to both the built-in memory and the attachable external memory. In this case, the data can be stored in the built-in memory continuously, and sufficient storage capacity can be secured. Furthermore, it is possible to read from either internal memory or external memory,
Since it is made reproducible, a desired captured image can be easily and quickly reproduced without using a special external storage and reproducing device.
