CDS403 is CCD40
This is to perform sampling for double correlation on one output image signal. The A / D converter 404 converts an analog output image signal of the CCD 401 into digital data. In this embodiment, the A / D converter 404 uses an 8-bit A / D converter. However, an appropriate number of bits can be selected according to the required image quality. Internal memory
Reference numeral 405 denotes an SRAM having a short access time, for example, an SRAM for taking in serial data from the CCD 401 and storing image data. The internal memory 405 has a work area serving as a work at the time of image processing, in addition to an image area having a capacity capable of storing at least one captured image. The internal memory 405 also stores the result of the data compression processing performed by the processor 407.

The address controller 406 receives a clock from the CCD-TG 402 when fetching data from the CCD 401 and
5 serially outputs a write address signal, decodes an I / O output and an address signal output from the processor 407 for processing and outputs an address signal to the internal memory 405,
Further, the serial clock is read at a low speed in order to write the processing result data to an external recording medium such as the IC card 2. The table ROM 408 stores coefficient data for WB when correcting white balance (hereinafter referred to as WB) described later, and γ when performing color conversion for printer and TV.

The γ correction processing is for converting the color-converted data to a predetermined value. ROM 408 storing the conversion coefficients
The data is further converted through. In the compression processing, for example, the original data is separated into a luminance Y signal and a color difference C (U, V) signal, compressed to 2/3, and a difference from a previous value is calculated for each of Y, U, and V. This is a CD-I DYUV compression method shown in Table 1 in which the data is compressed to 1/2 and the whole is compressed to 1/3.

The 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 is buffer 4
It outputs the stored contents of 09 and generates read and write address signals for writing to the IC card 2.

The gate 411 switches the connection between the internal memory 405 or the IC card 2 and the processor 407 and connects the internal memory 405 to the IC card 2, and is controlled by the CPU 301. Reference numeral 413 denotes a device for converting an analog signal of the WB sensor 412 into a digital signal, and reference numeral 210 denotes an internal battery of the IC card 2.

The processed image data is stored in the internal memory 405 again.

On the other hand, if the data can be stored in the IC card 2, the CPU 301 switches the gate 411 to connect the internal memory 405 to the IC card 2 and to output address signals to the address controllers 406 and 410. As a result, the image data in the internal memory 405 is transferred into the IC card 2 via the buffer 409.

Next, a block diagram of the printer unit will be described with reference to FIG.

The address controller 414 transfers the compressed image data subjected to each processing in the IC card 2 to a predetermined position in the processing work memory 416 in accordance with a command from the processor 415. The term “predetermined” means, for example, that data is stored for each row of the memory. The address controller 414 decodes an address signal from the processor 415 at the time of each signal processing described later and decodes the address signal from the work memory 4.
An address signal is output to 16. Work memory 416
Is an SRAM having a short access time, for example, an SRAM, which is used for processing of taking in compressed data in the IC card 2, temporarily storing data, and storing processing results. The table ROM 417 is pre-written with gamma correction coefficient data for converting TV image data into printer image data and bitmap data for area gradation to be described later for shading the printed pixels. ing. The processor 415 demodulates the compressed data in the IC card 2, that is, converts the decompression and data for the printer, and performs the γ correction and the area gradation using the table ROM 417. That is, the compressed data is expanded to generate a luminance Y and a color difference C signal described later, and a complementary color signal matching the color of the ink of the printer is created from these signals. Then, gamma correction is performed from the complementary color signal according to the printer. Further, for each color of each pixel, area gradation is performed using the bit map of the table ROM 417, and the result is written to the line sequential memory 418 to create data for each line having a 4-dot width. The processor 415 outputs an end signal to the CPU 301 each time the above processing is completed for one row. In the case of the above-described CD-I system, the decompression process of the compressed data calculates a true difference based on the data of the IC card 2 and adds this difference data to the value of the immediately preceding data to obtain the original data. In the case of the ADCT method to be described later, the data of the IC card 2 is reproduced to the original data by performing the inverse conversion of the conversion performed at the time of compression. The gamma correction process uses the image data created for TV as a table RO
The image data is converted into image data for a printer using M. Also, the area gradation is performed by setting the color intensity of each pixel to 4 bits × 4.
This is converted into the number of dots to be printed out of 16 bits. The 4 bits × 4 bits are regarded as one unit (one pixel) and the line sequential memory 418 is used.
Is taken in sequentially.

The line sequential memory 418 stores 4 bits × 4 bits for each pixel.
The 4-bit data for one line is stored, converted into data for one line (number of horizontal pixels × 4), and stored in the buffer 4 of the printer head 420.
Output to 19. The head 420 heats the output of the line sequential memory 418 and the buffer 419 to thermally transfer the ink to paper. The operation of the above block diagram will be described.

In the print mode, the print operation is started when the CPU 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, a frame (page) in which the image to be printed is stored in the internal memory 405 is selected by the address controller 406, and the work is performed via the gate 414 and the processor 415. Stored in the memory 416. Next, the CPU 301 instructs the processor 415 to perform signal processing for printing.

The processor 415 receives an instruction from the CPU 301, reads out image data from the work memory 416, and sets Cy (cyan), Ye
The above-described processing is performed in the order of (yellow), Mg (magenta) and Bk (black) ink colors. When detecting the end of the processing for one line, the CPU 301 controls the line sequential memory 418 and the head 420 to execute the printing for one line. Each time the printing operation of one line is completed, the head 420 is moved by one line in the direction of the arrow in FIG. 2B to prepare for printing of the next line. In this way, the printing process of one frame of image for one color is completed. When the printing process for one color Cy (cyan) is completed, Ye continues.
(Yellow), Mg (magenta), and Bk (black) are repeated in the order described above, thereby completing the printing of one frame of image.

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

FIG. 6 is a block diagram of the TV reproduction. The address controller 421 transfers the compressed image data in the IC card 2 to a predetermined position of the video output memory 423 in response to a command from the processor 422. The term “predetermined” means, for example, that data is stored for each row of the memory. The address controller 421 decodes the address signal from the processor 422 at the time of signal processing, outputs an address signal to the video output memory 423, and further outputs a composite signal from the video output memory 423,
Generates a read serial address and a clock for the D / A converter 424. The video output memory 423 has a short access time, for example, an SRAM, takes in compressed image data in the IC card 2, temporarily stores processing data during signal processing,
It is used for storing an NTSC video signal which is a result of the processing. The processor 422 expands the compressed image data. At this time, the processor 422 encodes the luminance Y and color difference C signals to create an NTSC composite signal. This expansion process is performed in the same manner as described above. In the encoding, the chrominance C signal is modulated using subcarriers and added to the luminance Y signal. The A / D converter 424 decodes the NTSC composite signal into an analog TV signal. The 75Ω driver 425 is for matching with the TV.

The operation at the time of TV output will be described with reference to the above block diagram.

When the CPU 301 detects that the TV playback mode has been set,
The reproduction operation by the TV is started. When an image stored in the IC card 2 is played back on a TV via the TV output terminal 113, the 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. Will be transferred. On the other hand, when the image in the internal memory 405 is to be reproduced by TV, the frame (page) in which the image to be reproduced in the internal memory 405 is stored is selected by the address controllers 406 and 421, and the gate 411 and the processor 422 are selected.
Via the video output memory 423. Then C
The PU 301 enables communication between the processor 422 and the address controller 421, and instructs the processor 422 to perform signal processing for TV reproduction.

The processor 422 receives an instruction from the CPU 301, reads out image data from the video output memory 423 line by line, performs each process described later, and obtains a digital NT
The SC 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. If the original image is a field image having a horizontal line density of 1/2, a pseudo-frame image process is performed when writing the image data to the video output memory 423, so that one frame image is stored in the video output memory 423. I do. When the processing for one frame is completed, the processor 422 outputs an end signal to the CPU 301. Upon detecting the end signal, the CPU 301 switches the address controller 421 for NTSC output,
As a result, the NTSC composite signal is output from the video output memory 423, and the D / A converter 424 is operated to output an analog TV signal.

In each of the above modes, shooting, printing, and output to a TV are performed.

FIG. 7 shows a flowchart of data processing executed after the image signal of the CCD 401 is A / D converted and taken into the internal memory 405.

First, in step # 11, WB correction is performed on the R and B signals so that they have the same level as the G signal. This is based on the colorimetric system 41
Using a color temperature coefficient determined by the color temperature information from 2, 413, correction is performed so that the same signal level is obtained when a reference white image irradiated with light of the set color temperature is taken. is there. This WB correction is performed 256 times (768/3) in the column (horizontal) direction in units of three RGB pixels shown in FIG. 8, that is, for one row.

Next, γ correction is performed on the G signal and the R and B signals subjected to the WB correction in # 12. This gamma correction is also performed sequentially for one row in the column (horizontal) direction for each of the three RGB pixels as described above.

With respect to the WB-corrected and γ-corrected signal, in # 13,
For example, matrix processing is performed using an arithmetic expression described below to create a low-frequency luminance signal (Y) and color difference signals (RY, BY) (# 14).

Y = 0.30R + 0.59G + 0.11B RY = 0.70R−0.59G−0.11B BY−0.8 = 0.89R−0.59G−0.30B Subsequently, low-frequency processing of the luminance signal Y is performed in # 15. , # 16, each of R, G, and B is multiplied by a predetermined coefficient so as to reduce aliasing distortion of each pixel, and the levels of R, G, and B that form dot-sequential signal levels in a high-frequency region are adjusted. . The low frequency (# 15) and high frequency (# 16) processing is the same as above
The processing is sequentially performed for one row in the column (horizontal) direction in units of three RGB pixels. When the above processing is completed, then, in steps # 17 and # 18, band limitation of the chrominance signal and the luminance signal is sequentially performed for one row in the column (horizontal) direction as necessary. Further, the low-frequency luminance signal and the high-frequency luminance signal obtained in # 15 and # 16 are frequency-added to generate a luminance signal (# 19). This process of creating a luminance signal is sequentially performed 256 times in the column (horizontal) direction, that is, for one row.

When this signal is reproduced on the TV after the above processes are completed, the burst signal and the horizontal and vertical signals are further added to the entire image and converted into a standard television signal such as an NTSC signal. (# 20- # 22).

The thermal head 420 scans the print frame 202 shown in FIG. When this scanning is repeated four times, that is, for four colors, the captured image is printed and reproduced by the combined color.

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

The CPU 301 controls the operation of the entire block. Reference numeral 431 denotes a print data creation unit including the processor 415, the line sequential memory 418, and the like.
The buffer 419 is, as described above, a line sequential memory 418.
The supplied parallel data of the number of bits for one row is converted into serial data and output to the head drive circuit 432. This head drive circuit 432 is
Is used to drive the thermal head 420 by heating. The mechanism control circuit 433 controls each mechanism shown in FIG. 9 based on an instruction from the CPU 301.
Head drive pulse motor 434 for driving thermal head 420 in the scanning direction, winding member for transfer ink film 201
A transfer ink film winding motor 435 for driving 220 and a color band detection sensor 222 are connected to each other.

The operation of the above block configuration will be described.

When detecting that the CPU 301 has shifted to the print mode, the CPU 301 outputs a print command signal to the head drive circuit 432. The head drive circuit 432 forms a heating signal to the thermal head 420 from one line of dot data supplied from the buffer 419 based on the print command signal from the CPU 301, and performs printing of the Cy color on the first line. You. The pulse motor 434 for driving the head drives the thermal head 420
On line 202, one line is moved in the direction of the arrow shown in FIG. By repeating the printing with the Cy color and the movement of the thermal head 420 alternately, the printing of the first color with the Cy color is completed. Thereafter, the CPU 301 causes the thermal head 420 to return to the reference position, that is, the first line by the head driving pulse motor 434, and the transfer ink film 204 to be transferred by the transfer ink film winding motor 435.
Is driven for one color to set the Ye color. Then, the printing using the Ye color and the thermal head 42 are performed as described above.
The printing of the Ye color is completed by repeating the movement of 0 alternately. Hereinafter, the same procedure is performed for the Mg color and the Bk color,
In this way, print reproduction of the image in the composite color is completed. Instead of the above printing method, each color of Cy, Ye, Mg, and Bk may be printed for each line as described above.

FIG. 12 is a block diagram in the case of performing monitor display on the display unit 106.

In the figure, the same reference numerals as in FIG. 6 denote the same items. The character output memory 440 displays the frame number displayed together with the image on the display unit 106, during printing, after printing,
Each character data sent from CPU 301 is written,
For example, a RAM or the like. Further, instead of the RAM, a character generator that outputs predetermined character data in response to an instruction signal from the CPU 301 can be used.

The synthesizing unit 441 is for synthesizing the video output and the character output to form one screen. The display device 442 is a display unit 106
For example, in a liquid crystal TV monitor, a D / A converter 4
The signal input from 24 is displayed on the monitor. The drive circuit 443 scans the display screen of the display unit 106 and applies a voltage to the liquid crystal element.

Since the monitor display on the display unit 106 is performed during the print operation or during the TV reproduction, the access button ST or SW is turned on after the print operation transition switch SP or the TV output switch SV is turned on. Display unit 106
The stored image is reproduced.

First, when an image is reproduced, the image data processed for TV output is stored in the video output memory 423 as described with reference to FIG. This image data is stored in the access button ST
Alternatively, it is stored in the IC memory 2 or the frame number in the internal memory 405 selected by the SW.

On the other hand, the display of the frame number, printing, completion of printing, and the like is performed by processing the data from the CPU 301 in the processor 422 and storing the data in the character output memory 440. The character data in the character output memory 440 and the video output memory 423
Are combined as one screen by the combining unit 441. That is, a frame number and an image corresponding to the frame number are displayed. Then, the synthesized data is guided to the display device 442 via the D / A converter 424 and displayed. As described above, when the start switch SR is turned on after the monitor display, the image displayed on the monitor is printed as described above.

In each block diagram of the camera, FIG. 13 to FIG.
The operation of the camera will be mainly described based on the photographing operation based on the flowchart of FIG. The operation of this camera 1 is as follows.
It is controlled by the CPU 301 and a program in a ROM (not shown) connected to the CPU 301.

When the power supply is mounted on the camera 1, a START routine shown in FIG. 13 is executed.

That is, first, it is determined whether or not the main switch SM is turned on (# 101). If the main switch SM is off (NO in # 101), the process proceeds to # 102 to reset the flag, and when the display is being displayed on the display unit 106, the display is turned off (# 103). Returning to step # 101, the system waits for the main switch SM to be turned on. When the main switch SM is turned on (YES in # 101),
Alternatively, if the power is already on when the power supply is mounted, an interrupt (INT) described later is made possible (# 104), and # 105
Proceed to.

At # 105, it is determined whether or not the start switch SR has been pressed to change from off to on. If the start switch SR is not pressed (NO in # 105), the flow returns to # 101 and the above-mentioned # 101
Repeat the routine from # 104 to # 104. On the other hand, when the start switch SR is pressed (YES in # 105), the power of the CCD 401 is turned on (# 106). That is, the power supply unit 307 is connected to the CPU 3 shown in FIG.
Receiving a signal (P) from 01 to supply a high voltage V _H as a power supply voltage to the CCD. At the same time as the start of this power supply, the CCD401
Is output to the CCD-TG 402,
Erasure of the residual charge of D401 is performed (# 107). Then
Exposure time T _V , aperture value A _V
Is calculated (# 108). Also, it is determined whether or not the subject has low brightness from the photometry result (# 109). If it is determined that the brightness is low (YES in # 109), first, the flash emission timing is set to perform flash photography. Calculation is performed based on the photometric value (# 111). Next, it is determined whether or not the charge required for the charge storage capacitor in the flash unit 305 has already been charged, and if the charge has not been completed (#
NO at 112), the unfilled flag is set to “1”, and charging is started (# 113, # 114). When charging is completed (YES at # 112),
Go to # 115. At # 115, the completion of charging is confirmed and charging is stopped. At # 116, it is determined whether or not the unfilled flag is "1". If the unsatisfied flag is “1” (YES in # 116), # 11
At 7, the unsatisfied flag is set to "0" and the process waits until the start switch SR is turned off (# 118). Then, when the start switch SR is turned off (YES in # 118), the process returns to # 101, and a so-called release lock is performed. On the other hand, if the unsatisfied flag is "0" in # 116, the flow shifts to # 119 to execute the exposure control 2 subroutine shown in FIG.

In FIG. 16, first, INT is prohibited in # 401, and the exposure time T _V and the aperture value A _V obtained by the photometric calculation are set to the exposure control unit.

Output to G402 to expose CCD401. When a signal indicating that the release has been started (exposure start) is input from the exposure control unit 306 (# 403), the CPU 301 starts a timer in the CPU 301 based on the flash emission timing obtained in # 111. (# 404). This flash fires at C
This is performed at a timing after a lapse of a predetermined time from the start of exposure of the CD 401. Next, the CPU 301 controls the exposure control unit.
It is determined whether a release completion signal has been input from 306 (# 405). This determination is made based on the above exposure time T _V
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 may output a release completion signal even before the flash emission timing is reached. It is. That is, when the exposure control unit 306 outputs a release completion signal before the flash firing timing (N in # 406)
O, YES in # 405), the exposure operation is terminated without firing the flash. On the other hand, if the flash emission timing is reached before the release is completed (YES in # 406), the flash is emitted and a release completion signal is output to the exposure control unit 306 (# 407, # 408), and the exposure operation is completed. Let it.

When the exposure operation is completed, it is determined whether or not the card flag is “1” at # 409. If the card flag is “1” (YES at # 409),
Control is performed to write the image signal captured by the CCD 401 to the mounted IC card 2 (# 411).
Control is performed to write the image signal captured in 1 into the internal memory 405 of the camera 1 (# 410). At this time, if the capacity of the internal memory 405 is saturated (YES in # 416), a warning by display or sound is issued (# 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. If the capacity is saturated (YES in # 412),
At step # 413, the card flag is set to "0", and at step # 414, a warning is issued. Note that the address of the internal memory 405 can be set so as to be continuous with the address of the IC card 2. By doing so, the user is notified that the capacity of the IC card 2 is saturated, The image signal can be written in the internal memory instead of the IC card 2. When the above processing is completed, INT is enabled in # 415 and the process returns.

On the other hand, if it is determined in the flowchart of FIG. 13 that the luminance 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, first, INT is inhibited in # 301, and the exposure time T _V and the aperture value A _V obtained by the photometric calculation are set to the exposure control unit.
306 (# 302). Exposure control unit 306 drives the diaphragm of the camera 1 on the basis of these data, CCD-T shutter control signal in accordance with the exposure time T _V
Output to G402 to expose CCD401. When a signal indicating that the release has been started (exposure start) is input from the exposure control unit 306 (# 303), the CPU 301 starts a timer for measuring the camera shake limit time (# 304). The camera shake limit time indicates the longest limit of the exposure time during which photographing is appropriately performed without camera shake, and becomes a problem when a relatively long exposure time without flash emission is required. After the timer is started, it is determined whether or not a release completion signal has been output from the exposure control unit 306 during the counting operation of the timer as in the case of the flash emission (#).
305). Before the camera shake limit time elapses (NO in # 306),
Upon reaching the exposure time T _V is the exposure control unit 306 outputs a release completion signal (YES at # 305), and terminates the exposure operation.
On the other hand, if the count of the timer is completed before the release is completed (YES in # 306), it is determined that the camera shake limit time has been reached, and the CPU 301 forcibly outputs the shutter close signal to the exposure control unit 306.

When this exposure operation is completed, it is determined whether or not the card flag is “1” in # 308 as in the processing of # 409 to # 417 in the routine of the exposure control 2, and if it is “1”, (# 308 In YE
S), the image signal captured by the CCD 401 is
Perform control to write to C card 2 (# 310).
The image signal captured by the CCD 401 is stored in the camera 1 internal memory.
Control for writing to 405 is performed (# 309). At this time, if the capacity of the internal memory is saturated (YES in # 315), a warning by display or sound is issued (# 316). After the image signal is written to the IC card 2, it is determined whether or not the capacity of the IC card 2 is saturated as described above, and if the capacity is saturated (YE in # 311).

Five). If the charging is not completed (NO in # 125), the unfilled flag is set to "1" and charging is started to complete the charging (# 126, # 127). On the other hand, when charging is completed (YES in # 125), the unfilled flag is set to “0” and charging is stopped. (# 128, # 129). After this, again # 10
It returns to 1 and repeats the above operations # 101 to # 129.

Next, after # 104 in which INT was enabled, this INT
The processing executed when the error has occurred will be described with reference to the flowchart of FIG. This INT is generated when any one of the switch SC for detecting the presence / absence of the IC card 2, the switch SP for detecting the shift to the print operation, the switch SV for instructing TV reproduction, and the access buttons ST and SW is turned on.

When this INT occurs, it is determined whether or not the unfilled flag is “1” in # 201. If it is “1”, it is determined that INT has occurred during charging of the charge storage capacitor, and # 202 To stop charging once, and if it is "0", skip # 202 and determine whether the switch SC has been turned on from off in # 203. If the switch SC remains off (NO in # 203), I

Returning to FIG. 14, it is next determined whether or not the switch SP has been turned on from off. When the switch SP is turned on (YES in # 207), it is determined that the movable portion 101a has been pulled out and the printing operation has started, and the process proceeds to # 208. On the other hand, when the switch SP remains off (NO in # 207). ), Proceed to # 229. # 20
At step 8, a display indicating that the camera is currently in the print mode is performed, and then it is determined whether the access button ST is turned on from off, that is, whether or not the access button ST is pressed (# 209). When the access button ST is turned on (YES in # 209), the process proceeds to # 210,

Is a conversion unit having a decompressor 501A, which adds the previous value to the differentially compressed image data to return to the original image data.

The image data in the IC card 2 is stored in the form of differentially compressed NTSC signals. The differential 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.

The conversion unit for processing includes a decompressor 601A, a color difference conversion circuit 602A, and a difference compression circuit 603A.

The image data in the IC card 2 is stored in the form of differentially compressed NTSC signals. The differential compressed data output from the IC card 2 is returned to the original image data by the decompressor 601A. Next, the color difference conversion circuit 602A separates the luminance Y signal and the color difference C signal from the decompressed image data, and the next stage compression circuit 603A differentially compresses the luminance Y signal and the color difference C signal.

The image data in the IC card 2 is stored in the form of differentially compressed NTSC signals. The differential 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. However, after a predetermined thinning process is performed by the thinning circuit 702A in consideration of the transmission capacity of the telephone line, the TV

A conversion unit that converts and further compresses data.
It has a conversion circuit 802A and an ADCT compression circuit 803A.

The MPU 808A controls the entire block, manages the flow of image information, and performs general control such as communication control and network control. The RGB conversion circuit 802A converts the original image data that has undergone the expansion processing into RGB color signals. The ADCT compression circuit 803A is a type of transform coding based on the standards of ISO / JTC1 / SC2 / WG8 and N800, and performs orthogonal transform of an image signal to extract a plurality of signals from low frequency to high frequency. Of these, in general, attention is paid to the fact that the higher the frequency component, the lower the correlation with the original signal, and the higher the frequency of the signal, the smaller the number of sampling bits, to compress the data. So
Not only high-frequency components but also the number of sampling bits of a certain frequency component can be reduced. And
The screen is divided into blocks each having an appropriate number of pixels, and a numerical sequence composed of sample values is orthogonally transformed for each block. That is, in this embodiment, the ADCT compression conversion is performed by dividing the image signal into blocks of 8 × 8 pixels, and then performing two-dimensional DCT (Discrete Cosine).
Transform). Each transformed term becomes more independent (more irrelevant) than the original sample value, thereby suppressing redundant information.

The memory 804A is used as a transmission buffer. The communication control unit 805A executes a predetermined facsimile transmission control procedure to execute transmission of image data with the partner station. The modem 806A modulates digital data so that a public telephone line, which is an analog line network, can be used for transmission.

Next, a process of determining the presence or absence of an operation input from the operation panel of the CD-ROM driver 3, the remote controller 5, or the keyboard 6 is executed (S2). When the operation input process is completed, a display mode setting process for setting the contents to be displayed on the monitor on the TV 7 is executed (S3). Next, an image transfer process for transferring the set contents to be displayed to the image memory 354 is executed (S4).

Hereinafter, each process will be described.

First, the operation input processing (FIG. 37, S2) will be described with reference to the flowchart in FIG. Using the CD-ROM driver 3, the remote controller 5, or the keyboard 6, it is determined whether there is an input from the function keys 371, 381, 391 (S11). If there is an input (S11
YES), set a function code indicating that there has been an input by a function key (S12), and return. Conversely, if there is no input by a function key, the flow shifts to S13, where the character code of the keyboard 6 is used. Determine if there is any input.

Next, FIG. 40 shows a subroutine for function processing shown in S22.

In S31, it is determined whether or not the display screen of the TV 7 is in the menu mode. In the case of the menu mode (YES in S31),
Subroutine of menu processing in S32 (described later in FIG. 41)

In S33, it is determined whether or not the mode is the standard screen mode. The standard screen mode is a mode in which one image is displayed on the screen of the TV 7. In the case of the standard screen mode (YES in S33), S34
Executes a subroutine of standard screen processing (described later in FIG. 42) and returns. If you are not in standard screen mode,
In S35, it is determined whether or not the mode is the multi-screen mode. The multi-screen mode refers to a mode in which the screen of the TV 7 is divided and a plurality of images, in this embodiment, 20 images are divided and displayed as described later. In the case of multi-screen mode (YE in S35
S) and S36, subroutine of multi-screen processing (No.
43, which will be described later, and then return. If the mode is not the multi-screen mode, it is determined in S37 whether the mode is the data input mode. In data input mode (Y in S37
ES), execute a data input processing subroutine in S38, and return. If the mode is not the data input mode, the process returns.

FIG. 41 shows a subroutine of menu processing in S32.

Hereinafter, this subroutine will be described with reference to an example of a menu screen shown in FIGS. 48 to 52.

First, FIGS. 48 to 51 will be described. In FIG. 48, (a) shows a menu mode as an initial screen. In the screen, a white portion indicates a selection position of a cursor key. (A) When "reproduction" is selected on the screen, reproduction display is performed on the TV 7. That is, when the enter key is turned on (selected) in “playback”, a screen (b) showing the type of the recording medium on which the image to be played is stored is displayed as shown in the screen (b). Here, for example, when "Disc" is selected on the screen (b), a disc (corresponding to CD-ROM4) is displayed as shown in the screen (c1).
The album number corresponding to the recording block in is displayed. Then, when "Album 1" is selected on the (c1) screen, a screen showing a reproduction display mode or the like is displayed as shown on the (c2) screen. Will be reproduced. On the other hand, when "Card 1" is selected on the screen (b),
(C2) As shown on the screen, a screen for reproducing and displaying the image stored in the card 1 or a screen for the presence or absence of the search appears. Each screen is sequentially returned to the previous screen by turning on the return key. For example, the screen (c1) returns to the screen (b), and when the return key is turned on, the screen returns to the screen (a).

FIG. 49 shows a case where “copy” is selected in the menu mode. (A) When "Copy" is selected on the screen,
(B) The type of image transfer between a plurality of recording media is displayed like a screen. Here, when "Card 1 → Disc" is selected on the screen (b), an album number indicating a block for storing an image transferred from the IC card 1 is displayed as shown in the screen (c). Then, when "Album 1" is selected on the screen (c), an image transfer mode is displayed. (D) When the enter key is pressed in the state of the screen, the image in the IC card 2 is transferred to the album in the disk in the form of the standard screen and recorded. As described above, when the return key is turned on, the display sequentially returns to the previous screen.

FIG. 50 shows a case where “Erase” is selected in the menu mode. When "Erase" is selected on the screen (a), the type of the recording medium to be erased is displayed as shown in the screen (b).
Here, when "card 1" is selected on the screen (b), (c)
The form of the screen to be erased as in 1) is displayed. On the other hand, when "Disc" is selected on the screen (b), the album number to be erased from the disc is displayed as shown in the screen (c2). Then, when "Album 1" is selected on the screen (c2), the form of the screen to be deleted is displayed. And (d2) "standard screen" or "multi-screen"
When 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 and individual images can be designated, and once reproduced and confirmed, the image can be deleted in units of designated images. As described above, when the return key is turned on, the display sequentially returns to the previous screen.

FIG. 51 shows a case where “auxiliary function” is selected in the menu mode. (A) When "auxiliary function" is selected on the screen, the title of "data input" and other functions, which will be described later, are displayed as in the screen (b). As described above, when the return key is turned on, the display sequentially returns to the previous screen.

Now, in FIG. 41, the discrimination is performed by the function keys of the CD-ROM driver 3, the remote controller 5, or the keyboard 6. That is, when the cursor key is pressed (turned on) (YES in S41), the menu selected in S42 is changed. For example, when the cursor key is turned on on the screen in FIG. 48 (a), the white portion moves to “copy”, and the “copy” becomes selectable. Further, when the cursor key is turned on, the white portion moves to “delete”. If the cursor key has not been pressed, it is determined in S43 whether the enter key has been turned on. If the enter key is turned on (YES in S43), the mode is shifted from the next menu or menu mode to the screen mode in S44. For example, if the enter key is turned on on the screen in FIG. 48 (a), the screen moves to the screen (b). If the enter key is turned on further, the screen moves to the screen (c1). When the enter key is turned on on the screen (c2) in the same figure, the IC card 1
Is displayed on the TV 7 on a standard screen. If the enter key has not been pressed, it is determined in S45 whether the clear key has been turned on. If the clear key is turned on (YES in S45), the screen returns to the previous menu screen in S46. For example, when the clear key is turned on on the screen in Fig. 48 (c1),
(B) Return to the screen and turn on the clear key again.
(A) Return to the screen. FIG. 42 shows a subroutine of the standard screen process shown in S34.

Also in this processing, the discrimination is performed using the function keys of the CD-ROM driver 3, the remote controller 5, or the keyboard 6. That is, when the cursor key is pressed (turned on) (YES in S51), the image currently reproduced on the TV 7 is changed to the next image or the previous image in S52. If the cursor key has not been pressed, it is determined in S53 whether or not the enter key has been turned on. If the enter key is turned on (YES in S53), in S54, the timer for automatically sequentially feeding the playback screen is started or stopped, and the operation returns to the image feeding by the cursor key. If the enter key has not been pressed, it is determined in S55 whether the clear key has been turned on. If the clear key is turned on (YES in S55), S56
To return to the menu mode screen or multi screen.
For example, if the clear key is turned on while an image is being reproduced on the TV 7, the display returns to the menu mode such as the screen shown in FIG. 48 (c2). When the screen is shifted from the multi-screen to the standard screen, when the clear key is turned on, the screen returns to the multi-screen again.

Here, the multi-screen will be described with reference to FIG.

The multi-screen includes a display section D ₁ for reproducing, for example, 20 frames of images in a TV screen, a type of a recording medium on which a reproduced image is stored,
"Front group for selecting the display section D _2, prior to the 20 frame of the image or the next 20 frame of image, to be displayed, for example, as shown," Card 1 → "on the lower the display unit D ₁ ", and a display unit D ₃ and D ₄ of the" next "group. In addition, SF ₁ can be used to operate each image area or each display section in the display section D ₁ by operating the cursor keys.
D ₂ to D ₄ is a selection frame was made to be movable. Then, when the enter key is turned on, processing described later with reference to FIGS. 43 and 44 is executed.

FIG. 43 shows a subroutine of the multi-screen mode shown in S36.

Also in this processing, the discrimination is performed by the function keys of the CD-ROM driver 3, the remote controller 5, or the keyboard 6. That is, (turned on) the cursor key is pressed when (YES at S61), moves the selection frame SF ₁ in the vertical and horizontal directions within the multi-screen of the currently played S62 in TV7, the selected image or the display to change the selection of part D ₂ to D _4. If the cursor key has not been pressed, it is determined in S63 whether the enter key has been turned on. If the enter key is turned on (YES in S63), a subroutine of the enter process in the multi-screen mode (described in FIG. 44) is executed in S64. If the enter key has not been pressed, it is determined in S65 whether or not the clear key has been turned on. If the clear key is turned on (YES in S65), the screen returns to the menu mode screen in S66. For example, if the clear key is turned on while the multi-image is being reproduced on the TV 7, the display returns to the menu mode such as the screen shown in FIG. 48 (c2).

FIG. 44 shows a subroutine of the enter process in the multi-screen mode described above.

[0173] First, in S71, the display unit D ₃ shown in FIG. 52, D ₄ is selection frame SF ₁
It is determined whether or not is selected. Display D ₃ ,
D ₄ and is selected (at S71 YES), reproduces the front group 20 frames of image, or the image of Tsugigun 20 frame of at S72. Display
D _3, if the D ₄ is not selected, it is determined whether the multi-screen playback mode at S73. And a reproduction mode (YES at S73), to the standard screen displays the image selected in the selection frame SF ₁ in S74 (42 Figure, S62). If not in the reproduction mode, it is determined in S75 whether or not the mode is the copy mode. And a copy mode (YES at S75), the image that you selected in the selection frame SF ₁ at S76, for example, "card → Disk"
And copy it to the specified recording medium. If not in the copy mode, it is determined in S77 whether the mode is the erase mode. If it is in the erasing mode (YES in S77), the image selected in S78 is erased.

FIG. 45 shows a subroutine of the data input process shown in S38.

In this process, the discrimination is performed by the CD-ROM driver 3, the function keys of the remote controller 5 or the keyboard 6, and the character keys 392 of the keyboard 6. That is,
If the cursor key is pressed (turned on) (Y in S81
ES), the cursor display position is moved in S82, and when the enter key is turned on next (YES in S83), the search data input in S84 is registered. On the other hand, when the clear key is turned on (YES in S85), the search data at the cursor position is deleted in S86. Next, if the character key is pressed (YE in S87)
In S) and S88, search data is entered at the cursor position. This data input is performed by using the character key when recording to CD-ROM4.
With 392, the shooting location, date, and additional information are input as the search index of each album as a block. Also. You can re-enter after deleting.

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

When the display mode is set in the processing up to FIG. 45, the flow shifts to the image transfer subroutine. That is,
If the screen is to be played back in S91 (YES in S91), the image to be played back in S92 is transferred to the image memory 354 to prepare for image playback. In the case of the copy mode (YES in S93), an image to be copied is written in a recording medium to be copied in S94. In the case of the erasing mode (YES in S95), the target image is erased from the recording medium in S96. When this image transfer processing is completed, an image creation processing is executed next.

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

First, it is determined whether to display the menu mode. To display the menu mode (YES in S101),
At 102, a menu screen is created by the image processor 355. On the other hand, when playing back in the standard screen mode (S103
YES), the image in the image memory 354 is reproduced as it is. When performing playback in the multi-screen mode (S104
In step S105, the image in the image memory 354 is subjected to a predetermined thinning process by the image processor 355, and then a multi-screen is created. If the data input mode is selected (YES in S106), the image processor 3 is selected in S107.
A screen for data entry is created by 55. After each of these processes is executed, the process returns.

The screen data created by the processing from S2 to S5 in FIG. 37 is output to the video interface 256 in S6 in FIG. 37 and reproduced or displayed on the TV 7. Further, after the processes of S7 and S8 described above are executed as necessary, the process returns to S2 again, and this process is sequentially repeated thereafter.

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