Abstract

PURPOSE:To simplify the input output constitution, to make the entire size small and to reduce the cost by displaying display picture visually based on a display picture data formed by 1st and 2nd forming means. CONSTITUTION:A picture signal received via a public line 31 is written in a RAM 18 and a CPU 12 saves the signal on a floppy disk after data processing. When a data display request instruction is inputted from a keyboard 22, selectors 4, 6 are thrown to the position of a CPU 12 and transferred to serial access memories 7, 8. A facsimile reception data written in the CPU 12 is displayed on a liquid crystal display device 20. Moreover, when a transmission request is discriminated, the data is read and displayed on the liquid crystal display device 20 or transmitted.

Next, the operation of this embodiment will be explained.

FIGS. 2A and 2B are flowcharts illustrating the control procedure of this embodiment.

First, the image display procedure of this embodiment will be explained using FIG. 2A.

When an instruction to input an image is given from the keyboard 22 with the video camera 30 already turned on, an NTSC signal is first input from the video camera 30 to the present apparatus.

Therefore, the synchronization separation IC2 separates the synchronization signal from the input NTSC signal into a horizontal synchronization signal and a vertical synchronization signal (
Step Sl). The AD control unit 3 detects the image capture start position from each separated synchronization signal, and creates an AD conversion clock, memory reset signal, and memory write signal from this (step S2). Selector 4 is AD
AD conversion clock from control unit 3 and CPU 1
For example, the CPU 12
When accessing from the CPU 12, a signal from the AD control unit 3 is output to the system RAM 18, and when accessing from the AD control unit 3, a signal from the AD control unit 3 is output to the system RAM 18 (steps 83 to S5). The selector 6 switches data using the same procedure (step S6). Normally, the selector 6 selects the input side of the NTSC signal from the AD converter 5. The selector 6 selects the CPU 12 side only when facsimile reception data, which will be described later, is displayed (step S7). The data digitized by the AD converter 5 is written into the serial access memories 7 and 8 by the reset signal and write clock supplied from the AD control unit 3 (step S8).

Data on the read side of one serial access memory 7 is connected to a data bus on the CPU 12 side. CPU
12 receives a transmission request from the keyboard 22 (step S9), reads data sequentially from the read port of the serial access memory 7, and develops it in the system RAM 18 (step 5IO). Furthermore, the system ROM
After compression and dithering image processing is performed by the program stored in 14 (step 5ll), the processed data is output to the public line 31 through the input/output control section 14 and the communication control section 15, and is then transmitted. (Step 51
2). In this way, until all data stored in the serial access memory 7 is transmitted, steps SIO to
Step S12 is repeated.

Further, the read port of the other serial access memory 8 is connected to the liquid crystal controller 11. Simultaneously with the above transmission, the read control unit 10 counts the number of display pixels from the display start signal start position of the display controller 16, and when the displayed pixel position reaches the NTSC information display position, from that time on, the read control unit 10 sends a read signal to the serial access memory 8. Start giving. The read contents are input to the liquid crystal controller 11. The liquid crystal controller 11 detects the NTSC information display position from the display start signal and the number of pixels in the same manner as the read control section 10.Step 51
5), a split screen display process is performed in which display contents are sequentially switched until all data is displayed (step S16.
Step 517) Note that NTSC multilevel information is expressed on the liquid crystal display 20 by frame thinning. Further, if there is no transmission request in step S9, step S9
Only split screen display after 14 is performed.

As described above, the video signal (NTSC video data) input from the small COD video camera 30 is displayed in a split-screen manner on the system display screen on the liquid crystal display 20, and at the same time, the video signal is converted into digital data from the video camera 30. It is possible to take in the data and send it to the public line 31.

Next, the operation of this apparatus during reception will be explained using FIG. 2B.

The image signal (facsimile reception data) received via the public line 31 is transmitted to the communication control unit 15 and the input/output control unit 1.
4 to system RAM 18 (step 520). After processing the data (image processing such as expansion) on the system RAM 1B, the CPU 12 saves the data on the floppy disk (FD) of the FDD 25 (step S
21° step 522). When a data display request command is input from the keyboard 22 (step 523), the CP
U12 switches selectors 4 and 6 to the CPU 12 side, and then transfers the data to FDD 23 to serial access memories 7 and 8 (step 524). Since the serial access memory 8 is always read at the timing of the display controller 16, the facsimile reception data written by the CPU 12 is immediately displayed on the liquid crystal display 20 (step 525). In this manner, a complete page-by-page display of the requested facsimile reception data is displayed (step 826). Further, if it is determined in step S23 that it is a transmission request, the above-mentioned second A
Operations similar to the transmission processing and display processing in the figure are performed (step 527). It is clear from the above operation that the data stored in the FD of the FDD 25 can be read out when necessary by operating the keyboard 22 and displayed or transmitted on the liquid crystal display 20.

As described above, according to this embodiment, the configuration for inputting images and visually outputting images can be simplified, making it possible to downsize the entire device, and at the same time reducing costs.

Now, in the embodiment described above, the NTSC input is performed using the small CCD video camera 30 of the external device, but the present invention is not limited to this, and the NTSC input is equipped with a small CCD video camera etc. as standard equipment. This may be realized by a configuration that is similar to the above.

In this case as well, the size can be sufficiently reduced compared to a scanner.

Further, in the above-described embodiment, transmission is always performed while displaying a split screen, but the present invention is not limited to this. The operation may be made more efficient by providing a mode in which both of the above are performed simultaneously.

Therefore, in the case of only transmission, writing of data to the serial access memory 8 is omitted, and in the case of only display, writing of data to the serial access memory 7 is omitted.

Furthermore, in the above-described embodiment, the NTSC signal output operation is of two types, display and transmission, but the present invention is not limited to this, and the transmission data stored in the serial access memory 7 F set in FDD23
It goes without saying that the data stored in the FD may be stored in the FD.In this case, the data stored in the FD is handled in the same way as facsimile reception data, and it goes without saying that this can be processed as transmission data or display data as necessary.

[Effects of the Invention] As described above, according to the present invention, the input/output configuration can be simplified, the overall size can be reduced, and costs can be reduced.
