Abstract

PURPOSE:To adjust the photographing position of a camera without expanding the size of a video telephone set by writing/reading out a video signal in/from a frame memory based on an address obtained from a writing address adjusting means and transmitting the written/read video signal to the opposite side. CONSTITUTION:A wide angle lens 6 is used for the camera 1, a memory write control means 4 is provided with a write address adjusting means 7 and a video signal is written/read out in/from the frame memory 5 based on an address obtained from a write address adjusting means 7 and the written/read video signal is transmitted to the opposite stage. Since the photographing position of the camera can be adjusted by adding the write address adjusting means 7 constituted of miniaturized electric parts, the video telephone set is never enlarged in its size.

As shown in FIG. 1, using the horizontal synchronization signal and vertical synchronization signal of the video signal of the camera 1, the count values of the tosoto counter 2, which counts the number of horizontal dots, and the line counter 3, which counts the number of vertical lines, are calculated. A television that generates an address by inputting it to a memory write control unit 4, writes the video signal from the camera 1 to a frame memory 5 at the address from the memory write control unit 4, reads it out, and transmits it to the other party. In the telephone, the lens of the camera 1 is a wide-angle lens 6 capable of photographing a screen (X dots x Y line) wider than the transmission screen (N dots - XM lines), and the memory write control unit 4 has X dots. Write address adjustment is performed to generate a write address for the N dot 1-XM line from the timing of outputting the desired value in the dot I counter 2 that counts up to the line and the line count 3 that counts up to the Y line. A stage 6 is provided, and a video signal is written into the frame memory 5 using the address from the write address adjustment means 6, and is output and transmitted to the other party.

On this transmission screen, for example, if only half of the face is photographed as shown in the transmission screen of FIG. In the present invention, in the write address adjustment step 7, the dot counter 2 that counts up to X dots generates an address of N dots x M lines from the timing of outputting the desired value and writes it to the frame memory 5, and then the transmission is performed. For example, the screen will be shifted to the right as shown in (B), and furthermore, Y
When the line counter 3 that counts up to the line generates an address of N dots x M lines from the timing of outputting the desired value and writes it into the frame memory 5, the transmission screen is shifted downward as shown in (C), for example. This is exactly the same as when the camera is directed to the right, 5 6 downward.
