When the image data is transmitted by the TV phone, the thinning unit 702 is used to transmit the TT for the TV phone.
Image data is thinned out according to the L compression method. The compression unit 703 compresses transmission data by a DCT signal from the MPU 601 when transmitting by FAX. The ADCT method can be used for data compression. This ADCT compression is
This is a type of code conversion based on the standards of SO / JTC1 / SC2 / WG8 and N800. That is, the image signal is orthogonally transformed and extracted as a plurality of signals from a low frequency to a high frequency. It is generally known that among these extracted signals, the higher the frequency component, the lower the correlation with the original signal.
That is, data compression can be performed by reducing the number of sampling bits for a signal having a higher frequency component. Since this image signal is converted into a frequency component, it is possible to reduce the number of sampling bits of a component of a certain frequency, not limited to a high frequency component. Then, an image is divided into blocks each having an appropriate number of pixels, and a numerical sequence of sample values is orthogonally transformed for each block. For example, in this ADCT compression conversion, an image signal is divided into blocks of 8 × 8 pixels and then a two-dimensional DCT (Discrete Cosine Transf
orm) to perform the orthogonal transformation. Each transformed term is more independent (more irrelevant) than the original sample value, thereby suppressing redundant information.

"CAM" in the switch 15 (switch S _CT ) shown in FIG.
When ERA "side of the button is pressed and contact piece S _CA is connected to the switch S _CT, i.e. the contact piece S _CA is turned on, flow - the flow proceeds to step # 811. On the other hand, the contact piece S _CA is when the turned off, assuming that "TV.TEL" side is selected, flow - the communication mode will be described later - proceeds to de.

In step # 811, the shooting start button 12
It is determined whether (switch S _RLS ) is on. When the switch S _RLS is off, the flow returns to step # 801 to repeat the above processing. On the other hand, switch S
_{When the RLS} is on, the flow proceeds to step # 812.

Steps # 812 to # 829 relate to control of the exposure operation. In step # 812, the game
Is switched to image storage. By this switching, the matrix unit 501 is connected to the compression unit 503.
Next, in step # 813, it is determined whether the switch S _IC is on. If the IC card 408 is mounted, it is further determined in step # 814 whether the storage capacity of the IC card 408 is saturated. When the IC card 408 is not mounted or the storage capacity of the IC card 408 is saturated, the IC card 4 of the image data is used.
08 becomes impossible. Therefore, the flow proceeds to step # 817. At step # 817, the flag ICCF is set to 0 to store the image data in the internal memory 407.
Is reset to. The gate 504 is the flag ICCF
Of the internal memory 4 in step # 818.
07. On the other hand, if the data can be stored in the IC card 408, the flow proceeds to step # 815, and the flag ICCF is set to 1. By setting this flag ICCF, in step # 816, the gate 504 sets the IC
It is switched to the card 408 side. After this, step # 8
At 19, the photometric unit 414 measures the brightness of the subject. Then, in step # 820, it is determined whether or not the measurement result is low luminance. If the subject is not low-luminance, the flow proceeds to step # 821, and executes a subroutine of exposure control 1. On the other hand, if the subject has low brightness, the flow proceeds to step # 822, and executes a subroutine for flash photography. These subroutines are shown in FIGS.

The exposure control 1 subroutine is described with reference to FIG. First, in step # 1010, the photometric unit 41
The exposure time T _V and the aperture value A _V obtained in step 4 are the exposure control unit 411.
Is output to The exposure control unit 411 drives the aperture of the camera unit 2 based on these data. At the same time, the exposure control unit 411 outputs a shutter control signal corresponding to the exposure time T _V to perform exposure by the CCD 403.
Output to G412. In step # 1020, a signal indicating the start of release (exposure start) is sent from the exposure control
When input to the PU 401, the CPU 401 proceeds to step #
At 1030, a timer is started to count the time limit for camera shake. The camera shake limit time indicates the longest limit of the exposure time for appropriate photographing without camera shake. Further, this hand-shake limit time is taken into consideration when the exposure is performed with a relatively long exposure time without using the flash. C
After the PU 401 starts the timer, in step # 1040, the CPU 401 determines whether or not the exposure end signal from the exposure control unit 411 is output during the counting operation of the timer. When the exposure time T _V before camera shake limit time has elapsed has elapsed, the exposure control unit 411 outputs an exposure completion signal to the TG412, to terminate the exposure operation. Meanwhile, when the camera shake limit time period has elapsed before the exposure time T _V has elapsed, in step # 1060, CPU 401
Forcibly outputs a shutter close signal to the exposure control unit 411 to end the exposure operation. After the end of the exposure operation, a subroutine for signal processing is executed in step # 1070. This subroutine is illustrated by FIG.

In step # 1310, the image data from the CCD 403 is matrix-processed by the matrix section 501. The processed image data is led to the compression unit 503. Then, in step # 1320, the image data is subjected to compression processing. At this time, it is determined whether or not the flag ICCF is set to 1 in step # 1330. If the flag ICCF is set, the R / W signal is switched to low in step # 1340. By this switching, in step # 1350, the image data is I
Written to C card 408. IC card for image data
After the writing to the node 408 is completed, in step # 1360,
The R / W signal is returned high. Thus, the subroutine of the signal processing ends. On the other hand, the flag ICCF is 1
If not, the R / W signal is switched to low in step # 1370. By this switching, step # 138
At 0, the image data is written to the internal memory 407.
After the writing of the image data to the internal memory 407 is completed, the R / W signal is returned to high in step # 1390. As a result, the subroutine of the signal processing ends as described above.

Next, the flash photographing subroutine will be described with reference to FIG. First, in step # 1110,
Flash emission timing is calculated based on the photometric value. Next, in step # 1115, it is determined whether or not the light emission energy required for flash photography has already been charged in the light emission energy charging capacitor in the flash unit 415. If charging is not completed, step #
At 1120, the unsatisfied flag is set to one. As a result, the CPU 401 sets the FCHG signal to high in step # 1125, and charging is started. When the charging is completed, the flow proceeds to step # 1130. In step # 1130, the FCHG signal is switched to low.
Subsequently, in step # 1135, it is determined whether the unfilled flag is 1. If the unfilled flag is 1, the unfilled flag is reset to 0 in step # 1140. Thereafter, in step # 1145, the CPU 401 waits until the switch S _RLS is turned off. And
When the switch S _RLS is turned off, the flow moves to step # 801, and a so-called release lock is performed. On the other hand, if the unsatisfied flag is 0 in step # 1135, the flow proceeds to step # 1150 to execute the subroutine of exposure control 2 shown in FIG.

In the exposure control 2 subroutine shown in FIG. 13, in step # 1210, the exposure time T _V and the aperture value A _V obtained by the photometric calculation are output to the exposure control unit 411. Exposure control unit 411 drives the aperture of the camera unit 2 based on the aperture value A _V. Exposure control unit 411
And it outputs the Le signal to TG412 - control - shutter in accordance with the exposure time T _V to perform exposure CCD 403. Next, in step # 1220, when the CPU 401 receives a signal indicating the start of exposure from the exposure control unit 411, in step # 1230, the CPU 401 proceeds to step # 1.
The timer in the CPU 401 is started in synchronization with the flash emission timing obtained in 110. The flash is emitted at a timing after a predetermined time has elapsed from the start of exposure by the CCD 403. Then step # 1
At 240, it is determined whether or not an exposure end signal has been input from the exposure control unit 411. The exposure time T _V is a predicted value. For example, when the subject brightness suddenly increases during the counting operation of the flash emission timer, an exposure end signal is output from the exposure control unit 411 before the flash emission timing is reached. The above-described determination is prepared in consideration of the possibility that the determination may be made. That is, when an exposure end signal is output from the exposure control unit 411 before the flash emission timing, the flow returns to step # 1240,
The CPU 401 ends the exposure operation without emitting a flash. On the other hand, if the flash emission timing is reached before the exposure ends in step # 1250, the CPU 401 causes the flash to emit light in step # 1260. Subsequently, in step # 1270, the CPU 401 sends an exposure end signal to the exposure control unit 411. Output. When this exposure is completed, as in the case of the subroutine of exposure control 1,
After executing the signal processing subroutine in step # 1280, the flow returns to the main routine shown in FIG.

In FIG. 8, when the operation of step # 821 or step # 822 is completed, the flow proceeds to step # 824 shown in FIG. Step # 82
At 4, the CPU 401 waits for the switch S _RLS to turn off. When this switch S _RLS is turned off, step #
At 825, it is determined whether or not charging of the capacitor in the flash unit 415 has been completed. If the charging of the capacitor has not been completed, the unfilled flag is set to 1 in step # 826, and the FC
The HG signal is made high. Thus, the charging is continued until the charging is completed, and the flow returns to step # 825. When the completion of charging is detected in step # 825,
In step # 828, the FCHG signal is set to low, and in step # 829, the unfilled flag is reset to 0. After this, the flow moves to step # 801 and the above operation is repeated.

Next, the communication mode will be described with reference to FIG. When the camera unit 2 is attached to the transceiver main body 1,
In step # 1401, the power supply control signal PWC signal is set to low. The power supply unit 413 stops supplying power to the CCD 403 due to the change of the power supply control signal PWC signal to low. Next, in step # 1403, the interface 417 transmits data between the CPU 401 and the MPU 601.
Data bus DB ₂ and data bus DB for data communication
Is switched to connect to. After this, step #
At 1405, it is determined whether the chip select signal CS is low. When the chip select signal CS becomes low, the CPU 401 starts receiving data from the MPU 601 in step # 1407. At this time, the data received from the MPU 601 is data indicating reception of image data and data regarding whether or not a telephone call is being made on the TV phone. Upon completion of the reception of the data, step # 140
At 9, the CPU 401 waits until the chip select signal CS goes high. When the chip select signal CS becomes high, in step # 1411, the CPU 401
It is determined based on the data from 1 whether or not the TV phone is busy.

If a call is in progress, in step # 1413,
The gate 506 is switched to the liquid crystal TV 17 side. The gay
When the switching of the step 506 is completed, in step # 1415,
Interface - Fe - scan 417, the image de received by the transceiver main body 1 - De As can input data - data bus DB ₁ and de -
It is switched to connect to the tabus DB. After this,
In step # 1417, the chip select signal CS goes low.
It is determined whether or not. When the chip select signal CS becomes low, the capture of the received image data is started in step # 1419.

At this time, since the videophone is in a call,
In step # 1421, the received image data is temporarily written to the buffer memory 507. Subsequently, this image data is sequentially read out, and in step # 1423, NT
It is guided to an NTSC signal creation unit 508 to convert the signal into an SC signal. Image is converted into an NTSC signal de - data is guided to the liquid crystal TV17 through an output terminal P _52. Then, in step # 1425, the received image is displayed on the LCD TV 17 as a monitor.

On the other hand, if the call is not in progress in step # 1411, the gate 504 is switched to the memory side (internal memory 407 or IC card 408) in step # 1427. In this case, the gate 504 gives priority to the IC card.
The mode is switched so that the image data is stored in the code 408. The gate 504 is used when the image data cannot be stored in the IC card 408 because the IC card 408 is not mounted or the storage capacity is already saturated. Switching is made so that image data is stored in 407. By allowing the received data to be stored in the memory during a non-call, a function similar to a so-called answering machine can be achieved.

When the switching of the gate 504 is completed, in step # 1429, the interface 417 receives the data bus DB ₁ and the data bus DB ₁ so that the image data received by the transceiver main body 1 can be input. -Switched to connect to Tabus DB. Thereafter, in step # 1431, it is determined whether the chip select signal CS is low. When the chip select signal CS becomes low, in step # 1433,
Capture of the received image data is started. At this time, as described above, the signal control unit 406 is selected by switching the gate 504 in step # 1435 in order to store the received image data in one of the internal memory 407 and the IC card 408. A low signal is output to one of the internal memory 407 and the IC card 408 as an R / W signal. With this low signal, the image data is written to the selected memory. When the writing of the image data is completed, the signal control unit 406 switches the R / W signal to high again. After this, the flow moves to step # 810 in FIG.

On the other hand, when it is determined in step # 1405 whether or not the chip select signal CS is low, when this chip select signal is not low, that is, when the transceiver body 1 does not receive an image, the flow is Proceeds to step # 1441 for executing access 2 subroutine. The subroutine of this access 2 is described with reference to FIG.

In FIG. 16, in step # 1500,
First, it is determined whether or not the access switch S _UP has been pressed. When the switch S _UP is pressed, that is, when the switch S _UP changes from off to on, the flow proceeds to step # 1505, and the address controller 41
The address output from 0 is counted up by 1. By counting up the address, the frame number in the internal memory 407 or the IC card 408 is increased by one frame.
The image data read from the C card 408 is changed. In step # 1510, the read image data is expanded by the expansion unit 505. Further step # 1515
The decompressed image data is sent to the NTSC signal generator 509.
Is converted to an NTSC signal. And step # 15
20, the output image emitted from the output terminal P ₅₂ - data is monitored on the liquid crystal TV 17 - is displayed. Step # 150 above
From 0 to step # 1520, each time the switch S _UP is turned on, the stored image is sequentially advanced one frame at a time and displayed on the monitor.

On the other hand, in step # 1525, the switch S
_{When DOWN} is pressed, that is, when the switch S _DOWN changes from off to on, the flow proceeds to step # 1530, and the address output from the address controller 410 is counted down by one. By counting down the address, the frame number in the internal memory 407 or the IC card 408 is reduced by one frame, whereby the image data read from the internal memory 407 or the IC card 408 is switched. Step # 15
At 35, the read image data is expanded by the expansion unit 505. Further, in step # 1540, the expanded image data is converted into an NTSC signal by the NTSC signal generator 509. Then, in a step # 1545, the output terminal P ₅₂
The image data output from is displayed on the liquid crystal TV 17 on the monitor. Steps # 1525 to # 15
By means of 45, each time the switch S _DOWN is turned on, the stored image is reversed by one frame and displayed on the monitor.

After the switched image is displayed on the monitor by turning on the switch S _UP or the switch S _DOWN , the flow goes through step # 1525 until the next switch S _UP or S _DOWN is turned on. Return to step # 1443 shown in FIG.

When each access to the stored image is executed, it is determined in step # 1443 whether or not the switch S _RLS functioning as a transmission button for transmitting the stored image is on. If the switch _SRLS is not on, the flow moves to step # 810. On the other hand, switch S
_{When the RLS} is on, the flow proceeds to step # 1445. In this step # 1445, the gate 504 is switched so as to connect the memory (the internal memory 407 or the IC card 408) and the decompression unit 505. When transmitting the image stored in the internal memory 407, the gate 504 is switched so as to connect the internal memory 407 and the decompression unit 505. On the other hand, this gate 504 is an IC card 4
When the stored image of No. 08 is transmitted, the IC card 408 and the extension unit 505 are switched so as to be connected. The stored image data read from one of the memories is returned from the compressed image to the original image by the decompression unit 505 in step # 1449. Next, in step # 1449, the gate 506 is switched to the interface 417. Further, in step # 1451, the chip select signal goes low.
To be. As a result, in step # 1443, the image data
The data is output to the transceiver main body 1 through the gate 506 and the interface 417. When the output is completed, the chip select signal is returned to high in step # 1455. Thereafter, the process proceeds to step # 810 in FIG.

Next, the operation of the MPU 601 on the side of the transceiver main body 1 will be described with reference to the flowcharts shown in FIGS.

FIG. 17 is a flowchart mainly illustrating the operation of the receiving routine. 17, first, in step # 1601, the MPU 601 performs data communication with the communication control unit 606. Next, in step # 1603, it is determined whether or not reception is performed. That is, the communication control unit 606
When has received the reception code data, the flow proceeds to step # 1605 to shift to the reception routine. on the other hand,
When the communication control unit 606 does not receive the reception code data, the flow shifts to a transmission routine shown in FIG. 18 described later.

Now, in the receiving routine, step # 16
At 05, the chip select signal is first made low. Then, the MPU 601 outputs to the camera unit 2 data indicating that the image signal has been received and that the user is talking or not talking on the TV phone. When the output of this data is completed, the chip select signal CS is returned to high in step # 1609. Next, in step # 1611, the NCU 608
Is controlled to connect the transceiver body 1 to a public telephone line. With this line connection, received data is input to the modem 607 through the line. Then, the received data
The data is demodulated by the modem 607 in step # 1613. Subsequently, in step # 1615, the MPU 6
01 outputs a low signal to the signal processing unit 603 as an R / W signal. Therefore, the received image is stored in the memory (internal memory 604).
Or it is written to the IC card 605). This writing is given priority to the IC card 605 as in the case of the camera unit 2. That is, when the storage capacity of the IC card 605 is already saturated or when image data cannot be stored in the IC card 605 such as when the IC card 605 is not mounted, the internal memory 604 is used. Next, the received image data is written. When the writing is completed, the R / W signal is returned to high again in step # 1619.

Next, at step # 1621, it is determined whether the reception is by FAX or the reception by TV telephone. In the case of reception by FAX, the flow is F # after step # 1625.
The mode shifts to the AX reception mode. On the other hand, in the case of reception by the TV telephone, the flow shifts to the TV telephone reception mode after step # 1637.

In the case of FAX reception, step # 1
At 625, the output control unit 706 is switched to be connected to the decompression unit 709. After this, the internal memory 604
Alternatively, the image data stored in one of the IC cards 605 is stored in the address controller 61 in step # 1627.
It is read by the read address from No. 4 and is input to the decompression unit 709 through the output control unit 706. The internal memory 604 or the IC card 605 stores FAX image data sent from another station in a compressed format. Accordingly, in step # 1629, the compressed FAX image data is converted by the decompression unit 709 so as to return to the original image data. Decompressed image de - data is input to a print signal generator 609 through the output terminal P _73. Then, in step # 1631, the decompressed image data is converted into a signal for printing by the print signal creation unit 609. As a result, the image data is stored in step # 16.
At 33, it is printed out by the printer 610.
Then, in step # 1635, the printed sheet is carried out to the document output port 4. When this printout is completed, the flow returns to step # 1601.

On the other hand, if it is determined at step # 1621 that the videophone call is received, then at step # 1637,
It is determined whether the switch S _SET is on. That is, it is determined whether or not the camera unit 2 is mounted on the transceiver main body 1. If the switch S _SET is not on, the flow returns to step # 1601. That is, in the case of reception by the TV phone, if the camera unit 2 having the liquid crystal TV 17 for displaying the received image is not mounted, the received image cannot be displayed, and the TV phone does not work.

On the other hand, when the switch S _SET is on, it is determined in step # 1639 whether or not a call is in progress.
If a call is in progress, the output control unit 7 proceeds to step # 1641.
06 is switched so as to be connected to the interpolation unit 707.
Thereafter, the internal memory 604 or the IC card 605
The image data stored in one of them is stored in step # 1643.
Is read by the read address from the address controller 614, passes through the output control unit 706, and is read by the interpolation unit 7.
09 is input. The internal memory 604 or the IC card 605 stores image data sent from another station in a thinned-out format. Therefore, step #
In step 1645, the thinned image data is converted by the interpolation method in the interpolation unit 709, and is returned to the original image data. On the other hand, if it is determined in step # 1639 that no call is in progress, the output control unit 706 is switched to be connected to the compression unit 708 in step # 1647. Thereafter, the image data previously stored in one of the internal memory 604 and the IC card 605 is read by the read address from the address controller 614 in step # 1649, and the output control unit 706 And input to the compression unit 708. The internal memory 604 or the IC card 605 stores image data sent from another station in a thinned-out format.
Data is stored. Therefore, in step # 1651,
The thinned image data is converted by the compression unit 708,

408).

Step # 1645 or Step # 16
When the conversion for interpolation or compression is completed at 51, the gate 704 is switched to the interface 615 at step # 1653. Further, in order to guide the interpolated or compressed image data to the camera unit 2, step #
At 1655, the interface 615 is the data bus DB.
₄ to be connected to the data bus DB.
Further, in order to output image data to the camera section 2, the chip select signal CS is set low in step # 1657. Thereafter, in step # 1659, the image data is output to the camera unit 2 through the gate 704 and the interface 615. When the output of this image data is completed,
In step # 1661, the chip select signal CS is returned to high. Further, after the interface 615 is switched to connect the data bus DB ₂ and the data bus DB in step # 1663, the flow proceeds to step # 1.
Return to 601.

Next, the transmission routine will be described with reference to the flow charts shown in FIGS. In FIG. 18, in step # 1701, it is determined whether the switch S _TEL is on. When the switch S _TEL is on, the flow shifts to a TV phone transmission routine shown in step # 1703 and thereafter.

The liquid crystal TV 17 of the camera section 2 is required for the transmission routine by this TV telephone. Therefore, first, in step # 1703, it is determined whether the switch S _SET is on. And when the switch S _SET is not on,
In step # 1705, a warning is issued to instruct that the camera unit 2 is not mounted, and the flow shifts to step # 1701. As a result of this warning, the camera unit 2
And the switch S _SET is turned on, the flow proceeds to step # 1707. On the other hand, if the switch S _SET is turned off during the warning, the flow proceeds to step # 174.
Move to 1. In step # 1707, it is determined whether the chip select signal CS input from the camera unit 2 is low. When the chip select signal CS is not low,
The flow moves to step # 1601. On the other hand, when the chip select signal CS is low, step # 1709
In the interface 615 is switched to be connected to the data bus DB data bus DB _4. Also,
In step # 1711, the input control unit 701 determines that the thinning unit 7
02. Thereafter, in step # 1713, the image data to be transmitted is input from the camera unit 2 to the thinning unit 702 through the interface 615 and the input control unit 701. When the input of the image data is completed, in step # 1715, the MPU 601 waits until the chip select signal CS becomes high. When the chip select signal CS is made high, the flow proceeds to step #
Proceed to 1717. In this step # 1717, the image data is thinned out by the thinning unit 702. When the thinning process is completed, the R / W signal is set low in step # 1719 so as to temporarily write the thinned image data into the memory (the internal memory 604 or the IC card 605). Thus, in step # 1721,
The transmitted image data is temporarily written in the memory. When the writing is completed, step #
At 1723, the R / W signal is returned high.

After this, processing for communication to the destination is started. That is, first, in step # 1725, MP
U601 is the communication control unit 6 for connecting the line with the partner station.
06 to send a signal. Then, when the transceiver main body 1 is connected to the public telephone line in step # 1727, the reading of the image data to be transmitted from the memory is started in step # 1729. At step # 1731, the read image data is modulated by the modem 607 so that the image data can be transmitted through a public telephone line. Then, in step # 1733, the modulated image data is transmitted to the transmission destination via the NCU 608. When this transmission is completed, in step # 1735, the data bus DB ₂ is switched to be connected to the data bus DB, and thereafter, the flow shifts to step # 1601.

On the other hand, if it is determined in step # 1701 that the switch S _TEL is not turned on, the flow proceeds to step # 17.
Go to 41. In this step # 1741, the switch S
It is determined whether the _fax is on. If the switch S _FAX is not on, the flow moves to step # 1601. On the other hand, when the switch S _FAX is on, the flow shifts to a FAX transmission routine shown in FIG.

In FIG. 19, in step # 1801,
A display on the LCD display unit 9 for requesting data input is performed. Subsequently, in step # 1803, it is determined whether or not the original to be transmitted is set on the original set table 3. If a document is set, step # 180
At 5, the display on the LCD display unit 9 for requesting the input of the fax number of the transmission destination is performed. In step # 1807, M
The PU 601 waits for the input key 6 to input the destination FAX number. Then, when this input is performed, reading of the original set on the original set table 3 is started by the FAX original reading unit 602 in step # 1809. When the reading of the original is completed, Step # 1
At 811, the input control unit 701 is switched to be connected to the compression unit 703. By this switching, the image data is guided to the compression unit 703. And step # 18
At 13, the image data is compressed. When this compression processing is completed, the R / W signal is set low in step # 1815 so as to temporarily write the compressed image data into the memory (the internal memory 604 or the IC card 605). Thus, in step # 1817, the transmitted image data is temporarily written in the memory. When this writing is completed, step # 1819
The R / W signal is returned to high.

After this, processing for transmission to the destination is started. That is, first, in step # 1821, MP

06 to send a signal. Then, in step # 1823, when the transceiver main body 1 is connected to the public telephone line, reading of the transmitted image data from the memory is started in step # 1825. The read image data is modulated by the modem 607 in step # 1827 so that the image data can be transmitted through a public telephone line. Then, in step # 1829, the modulated image data is transmitted to the transmission destination through the NCU 608. When the transmission is completed, in step # 1831, the data bus DB ₂ is switched to be connected to the data bus DB, Thereafter, the flow proceeds to step # 1601.

On the other hand, if the original is not set in step # 1803, it is determined in step # 1833 whether the switch S _SET is on. The switch S _SET is turned on, and further in step # 1835, the chip select signal C
When S is low, transmission of the image stored in the memory of the camera unit 2 is enabled. In this case, step # 1
At 837, the interface 615 connects to the data bus DB ₄
And data bus DB.
Further, in step # 1839, the input control unit 701 is switched to be connected to the compression unit 703. By this switching, image data is input from the camera unit 2 to the compression unit 703. When this input is completed, the chip select signal C
S waits for it to go high.

After this, the flow is the above-mentioned step # 18.
Proceed to 13 or later. That is, after the image data is compressed, it is temporarily written to a memory. Further, the image data is modulated by the modem 607 and then transmitted from the NCU 608 to the destination via a public telephone line.

On the other hand, in step # 1833, the switch S
_{When SET} is off, there is no image data to be faxed, so the flow moves to step # 1601. If the chip select signal CS is not low in step # 1835, it is determined that the camera unit 2 is not in a state where data transmission is possible, and the flow proceeds to step # 16 as described above.
Move to 01.

In this embodiment, the IC card is used as the recording medium that can be mounted on the camera unit 2 or the transmitter / receiver main body 1, but an analog memory such as a floppy disk may be used.

Further, an access button may be provided on the transmitter / receiver main body 1 so that the image data stored in the memory on the transmitter / receiver main body 1 side is displayed on the liquid crystal TV 17 of the camera section 2.
