FIG. 5 shows the signal processing unit 406 shown in FIG.
FIG. 2 shows a detailed block diagram of FIG. The RGB image signals guided to the input terminal P51 are temporarily written to the internal memory 407. Thereafter, the image data is read from the internal memory 407 and input to the matrix unit 501. The matrix unit 501 performs a matrix process on the RGB image data from the internal memory 407 to generate, for example, a luminance signal Y and a color difference signal C. The gate 502 is switched by the GATE1 signal from the CPU 401 to guide the matrix-processed image data to either the gate 506 or the compression unit 503. By this switching, the matrix-processed image data is stored in the memory or not, and is output via the output terminal P52 to the liquid crystal TV 17.
Will be displayed. When the image data is directly displayed on the liquid crystal TV 17, the liquid crystal TV 17 has the same function as the viewfinder of the camera at the time of photographing.

On the other hand, when the image data is stored in the memory, the image data is subjected to compression processing by the compression section 503 according to the TRAM1 signal from the CPU 401. For example, the compression unit 503 reduces the data amount by half by taking the difference between the luminance signal Y and the color difference signal C from the previous values. By this compression processing, the data amount of one image data is suppressed. Therefore, the number of frames of an image that can be stored is increased. The compressed image data is led to a gate 504. The gate 504 is the GA from the CPU 401.
Image data is stored in the internal memory 407 or IC according to the TE2 signal.
It is switched to lead to one of the cards 408.
The storage of image data is given priority to the IC card 408. That is, when the IC card 408 is mounted on the camera unit 2 and is in a storable state, the image data is written on the IC card 408. Otherwise, the image data is written to the internal memory 407. Such writing control of the image signal is performed by the CPU 401. The internal memory 407 has a storage capacity capable of writing at least image data directly input from the input terminal P51 and image data input through the gate 504.

Next, when the image data stored in the internal memory 407 or the IC card 408 is read, the image data is guided to the decompression unit 505 via the gate 504. The decompression unit 505 decompresses the compressed image signal based on the TRAM2 signal from the CPU 401 and returns it to the original image signal.

The gate 506 is a GAT from the CPU 401.
Switching is performed so that either the gate 502 or the decompressor 505 is connected to the buffer memory 507 by the E3 signal. The gate 506 is switched in conjunction with the gate 502. That is, the gate 506 selects the output of the gate 502 when displaying the image data in the viewfinder. Thereby, the image data obtained by the CCD 403 is obtained.
The internal memory 407 or IC card 408
It is led to. When the image data stored in the buffer memory 507 is reproduced and displayed, the image data from the decompression unit 505 is input to the buffer memory 507. On the other hand, when the image data received by the transmitter / receiver main body 1 is displayed on the liquid crystal TV 17, the gate 506 receives the G signal from the CPU 401.
The interface 417 and the buffer memory 507 are switched so as to be connected by the ATE3 signal. After the image data is once stored in the buffer memory 507,
The signal is sent to the NTSC signal generator 508. The NTSC signal creation unit 508 converts the sent image signal into an NTSC signal so that it can be displayed on the liquid crystal TV 17. Then, the converted image data is output from the output terminal P52 to the D / A converter 409 shown in FIG.

When transmitting image data using a V telephone, the image data is thinned out in accordance with the TTL compression method for a TV telephone. The compression unit 703 transmits the MPU 60
The transmission data is compressed by the DCT signal from step (1). Date
The ADCT method can be used for data compression. This ADCT compression is a kind of code conversion based on ISO / JTC1 / SC2 / WG8, N800 standard. 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, after an image signal is divided into blocks of 8 × 8 pixels, two-dimensional DCT (Discrete Cosin
e Transform) performs orthogonal transformation. Each transformed term is more independent (more irrelevant) than the original sample value, thereby suppressing redundant information.

The R / W control unit 705 stores the data in the internal memory 604 or the IC card 6 based on the R / W signal from the MPU 601.
05, a write / read enable signal (R / W signal) is output. The internal memory 604 and the IC card 605 can be read while the R / W control unit 705 outputs an R signal (high level). On the other hand, the internal memory 604 and the IC card 605 can be written while the R / W control unit 705 outputs a W signal (low level).

After this operation, the flow returns to step # 810 in FIG. In step # 810, it is determined whether the switch SSET is on. When the camera section 2 is detached from the transceiver main body 1, the flow proceeds to step # 811. On the other hand, when the camera unit 2 is mounted on the transceiver main body 1, the flow is step # 823.

When the CA is off, it is assumed that the "TV.TEL" side has been selected, and the flow shifts to a communication mode described later.

In step # 811, the shooting start button 12
It is determined whether (switch SRLS) is on. When the switch SRLS is off, the flow proceeds to step # 801.
And the above processing is repeatedly executed. On the other hand, when switch SRLS is on, the flow proceeds to step # 812.

Steps # 812 to # 829 relate to control of the exposure operation.

In step # 812, the gate 502 is switched for 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 SIC 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 when the storage capacity of the IC card 408 is saturated, it is impossible to store image data in the IC card 408. Therefore, the flow proceeds to step # 817. In step # 817, the flag ICCF is reset to 0 to store the image data in the internal memory 407. The gate 504 is switched to the internal memory 407 in step # 818 by resetting the flag ICCF. On the other hand, when the data can be stored in the IC card 408,
The flow advances to step # 815 to set the flag ICCF to 1
Set to. By setting the flag ICCF, the gate 504 is switched to the IC card 408 in step # 816. Thereafter, in step # 819, the photometry unit 414 measures the brightness of the subject. And step #
At 820, it is determined whether the measurement result is low brightness. 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 subroutine of exposure control 1 will be described with reference to FIG. First, in step # 1010, the photometric unit 41
The exposure time TV and aperture value AV obtained in step 4
1 is output. 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 TV to the TG 412 so that the CCD 403 performs exposure. In step # 1020, the relay
When a signal indicating the start of exposure (exposure start) is input from the exposure control unit 411 to the CPU 401, the CPU 401 starts a timer in step # 1030 in order to measure the camera shake limit time. The camera shake limit time indicates the longest limit of the exposure time for appropriate photographing without camera shake. Also, the camera shake limit time is considered when performing exposure with a relatively long exposure time without using a 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. If the exposure time TV has elapsed before the camera shake limit time has elapsed, the exposure control unit 411 outputs an exposure end signal to the TG 412 to end the exposure operation. On the other hand, if the camera shake limit time has elapsed before the exposure time TV has elapsed, the CPU 401 proceeds to step # 1060.
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.

At step # 1310, image data from the CCD 403 is subjected to matrix processing in the matrix unit 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 becomes 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 into 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 subroutine for flash photography 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 necessary 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 SRLS is turned off. Then, when the switch SRLS is turned off, the flow proceeds to step # 801, and so-called release lock is performed. On the other hand, if it is determined in step # 1135 that the unsatisfied flag is 0, the flow proceeds to step # 1150, and FIG.
The subroutine of exposure control 2 shown in 3 is executed.

In the subroutine of exposure control 2 shown in FIG. 13, in step # 1210, the exposure time TV and aperture value AV obtained by the photometric calculation are output to the exposure control unit 411. The exposure controller 411 drives the aperture of the camera unit 2 based on the aperture value AV. Exposure control unit 41
1 outputs a shutter control signal to the TG 412 in accordance with the exposure time TV so as to expose the 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 determines whether
The timer in the CPU 401 is started in synchronization with the flash emission timing obtained in 1110. The flash is emitted at a timing after a predetermined time has elapsed from the start of exposure by the CCD 403. Then step #
At 1240, it is determined whether or not an exposure end signal has been input from exposure control section 411. The exposure time TV is a predicted value. Therefore, 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 information may be lost. 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, and 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 emits a flash in step # 1260, and then the CPU 40 in step # 1270.
1 outputs an exposure end signal to the exposure control unit 411. When the exposure is completed, the flow returns to the main routine shown in FIG. 8 after executing the signal processing subroutine in step # 1280, as in the case of the exposure control 1 subroutine. .

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 SRLS to be turned off. When the switch SRLS is turned off, it is determined in step # 825 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 further in step # 827,
The FCHG signal is driven 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, the FCHG signal is set low in step # 828,
Further, in step # 829, the unfilled flag is reset to 0. Thereafter, 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 DB2 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, at 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,
The interface 417 is connected to the data bus DB1 and the data bus so that the image data received by the transceiver main body 1 can be input.
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 TV phone is busy,
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. The image data converted into the NTSC signal is led to the liquid crystal TV 17 through the output terminal P52. Then, in step # 1425, the received image is displayed on the liquid crystal TV 17 on the monitor.

On the other hand, if no call is being made 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 is preferentially an 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 connects the data bus DB1 to the data bus DB1 so that the image data received by the transceiver body 1 can be input. It is switched to connect to the 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. Thereafter, the flow moves to step # 810 in FIG.

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

In FIG. 16, in step # 1500,
First, it is determined whether the access switch SUP has been pressed. When the switch SUP is pressed, that is, when the switch SUP changes from off to on, the flow proceeds to step # 1505, where the address control is performed.
The address output from the label 410 is counted up by one. By counting up this address, the frame number in the internal memory 407 or the IC card 408 is counted.
Is increased by one frame, so that the image data read from the internal memory 407 or the IC card 408 is changed. In step # 1510, the read image data is expanded by the expansion unit 505. Step # 15
At 15, the decompressed image data is sent to the NTSC signal generator 5
At 09, it is converted to an NTSC signal. And step #
At 1520, the image data output from the output terminal P52 is monitored and displayed on the liquid crystal TV 17. Step # above
From step 1500, the switch S
Each time the 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 SDOWN changes from off to on, the flow proceeds to step # 1.
Proceeding to 530, 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 internal memory 407 or the IC card 4
The image data read from 08 is switched. In step # 1535, the read image data is stored in the decompression unit 5.
Expanded at 05. Further, in step # 1540, the decompressed image data is output to the NTSC signal generator 509 by the NTSC
Converted to a signal. Then, in step # 1545, the image data output from the output terminal P52 is output to the liquid crystal TV17.
Is displayed on the monitor. At steps # 1525 to # 1545, each time the switch SDOWN is turned on, the stored image is moved backward by one frame, and the monitor
Will be displayed.

Switch SUP or switch SDO
After the switched image is displayed on the monitor when WN is turned on, the flow returns to step # 1443 shown in FIG. 15 through step # 1525 until the next switch SUP or SDOWN is turned on. I do.

When such access to the stored image is performed, it is determined in step # 1443 whether or not a switch SRLS 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, when the switch SRLS is on, the flow proceeds to step # 1445.
Proceed to. 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 car.
When transmitting the stored image of the IC card 408, the IC card 40 is used.
8 is connected to the extension unit 505. 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 is set low. As a result, in step # 1443, the image 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, step # 8 in FIG.
Move to 10.

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

FIG. 17 is a flowchart mainly explaining the operation of the reception 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, at step # 1615, MPU6
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, in step # 1621, it is determined whether reception is by facsimile or TV phone. 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 reception by facsimile, 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.
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. The decompressed image data is input to the print signal creation unit 609 through the output terminal P73. 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 # 1.
At 633, 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 in step # 1621 that the call is received by a TV phone, in step # 1637
It is determined whether the switch SSET 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 SSET 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 SSET is on,
At step # 1639, it is determined whether or not a call is in progress. If a call is in progress, the output control unit 706 is switched to be connected to the interpolation unit 707 in step # 1641. Thereafter, first, the internal memory 604 or the IC card 6
The image data stored in one of the image data 05 is stored in step # 16.
At 43, the data is read by the read address from the address controller 614, and is input to the interpolation unit 709 through the output control unit 706. The internal memory 604 or I
The C card 605 stores image data sent from another station in a thinned-out format. Therefore, in step # 1645, the thinned image data is supplied to the interpolation unit 70.
In step 9, the image data is converted by the interpolation method and 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,
Memory of the camera unit 2 (internal memory 407 or IC card)
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 and 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 DB2 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 flowcharts shown in FIGS. In FIG. 18, in step # 1701, it is determined whether the switch STEL is on. When the switch STEL 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 unit 2 is required in the transmission routine by the TV phone. Therefore, first, in step # 1703, it is determined whether the switch SSET is on. If the switch SSET is not on, a warning is issued in step # 1705 to instruct that the camera unit 2 is not mounted, and the flow proceeds to step # 1701.
Move to As a result of this warning, when the camera unit 2 is mounted on the transceiver main body 1 and the switch SSET is turned on, the flow proceeds to step # 1707. On the other hand, if switch SSET is turned off during the warning, the flow moves to step # 1741. In step # 1707, it is determined whether the chip select signal CS input from the camera unit 2 is low. If 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, the interface 615 sets the data bus D in step # 1709.
It is switched so that B4 and data bus DB are connected. In step # 1711, the input control unit 701 is switched to be connected to the thinning unit 702. Thereafter, in step # 1713, the transmitted image data is transmitted from the camera unit 2 to the interface 615 and the input control unit 70.
1 to the thinning unit 702. When the input of the image data is completed, in step # 1715, the MPU 60
1 waits until the chip select signal CS becomes high. When the chip select signal CS is made high, the flow proceeds to step # 1717. In this step # 1717, the image data is thinned out by the thinning unit 702. When the thinning process is completed, the thinned image data is stored in the memory (the internal memory 604 or the IC card 60).
In step # 1719, R /
The W signal is pulled low. Thus, step # 1
At 721, the transmitted image data is temporarily written to the memory. And when this writing is completed,
At step # 1723, the R / W signal is returned to high.

Thereafter, processing for communication with 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 DB2 is switched to be connected to the data bus DB, and thereafter, the flow shifts to step # 1601.

On the other hand, if the switch STEL is not on in step # 1701, the flow proceeds to step # 1.
Proceed to 741. In this step # 1741, the switch S
It is determined whether the facsimile is on. If the switch SFAX is not on, the flow moves to step # 1601. On the other hand, when the switch SFAX 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. Then, 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.

Thereafter, processing for transmission to the destination is started. That is, first, in step # 1821, MP
U601 is a communication control unit 6 for connecting a line to a transmission destination.
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 this transmission ends, in step # 1831, the data bus DB2 is switched to be connected to the data bus DB, and thereafter, the flow shifts to step # 1601.

On the other hand, if the document is not set in step # 1803, it is determined in step # 1833 whether or not the switch SSET is on. Switch SSET
Is ON, and when the chip select signal CS is low in step # 1835, the transmission of the image stored in the memory of the camera unit 2 is enabled. In this case, in step # 1837, the interface 615 is switched so that the data bus DB4 and the data bus DB are connected. Further, in step # 1839, the input control unit 701
Are switched to be connected to the compression unit 703. By this switching, the image data is transferred from the camera unit 2 to the compression unit 703.
Is input to When this input is completed, it waits for the chip select signal CS to go high.

Thereafter, the flow proceeds to step # 18 described above.
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 transmitted by facsimile, 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, an IC card is used as a recording medium that can be mounted on the camera section 2 or the transceiver main body 1. However, an analog memory such as a floppy disk may be used.

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

[0083]

According to the present invention, a photographed image arbitrarily selected from a plurality of photographed images photographed by a camera is transmitted by a TV phone or a facsimile through a transmitter body equipped with the camera. The same captured image can be easily viewed even at a remote location that is a transmission destination.

According to the second aspect of the present invention, the image selected to be transmitted can be confirmed and displayed on the display means.
