Abstract

PURPOSE:To shorten a transmission time by providing an area designating part to designate the area to be specially displayed and the area to be transmitted out of video signals in a memory part and an address generating part to generate the address signal of respective areas and transmitting the designated area only. CONSTITUTION:A video signal from a camera 1 and a VTR 2 is stored in memory parts 6 and 7. When a light pen 9 is allowed contact with two points 15 and 16 on a monitor 3, the address signals of two points are written into the memory parts 6 and 7 as a representative signal to show an area 17 to be specially displayed. Next, when the light pen 9 is allowed to contact with points 18 and 19 on the monitor 3, an area 20 surrounded by a square to make two points into a diagonal line is decided to be the area to be specially transmitted and the address signal of two points is sent from an address generating part 8 as the representative signal. A cursor generating part 10 generates the cursor signal and the square shown by symbols 17 and 20 is displayed on the monitor 3. On the other hand, a CPU part 11, after the address signal corresponding to points 15, 16, 18 and 19 is transmitted through a signal control part 12 and a narrow band transmission line 13 to the receiving side, transmits the video signal of the memory parts 6 and 7.

Generally, in order to transmit a still image, the image to be transmitted is stored in a video memory, and as shown in FIG. 4, the image is read out and transmitted using a horizontal address or a vertical address y. Then, the input video signal begins to be written in the horizontal direction from the horizontal atsis O of the column of vertical address O, and when it is written by -horizontal scanning line, it is written to the column of vertical address 1 Km. When transmitting a video signal, the transmitting side transmits the signal 1. written in the video memory. (horizontal atsis, vertical address) from the (0,0) position (1,0), (2,0), etc., and when reading the -horizontal scanning line, the address is (o
, t), (t, t)..., and this operation is continued until the final address. The receiving side writes the encoded signals in the same order as the transmitting side. In other words, the memory contents written on the sending side are copied to the memory of the receiver 10111.

The operator selects the two points 15.1 on the screen 3 as shown in Figure 2.
6 with the light pen 911c, these two address signals are written into the memory section 6.7 as representative signals of the area representing the area to be specially displayed. Also, casa generation part 1
0 generates a cursor signal, so there is a point 15 on monitor 3.
.. A rectangle 17 having diagonal lines at 16' is displayed. Next, when the light pen 9 is touched on points 18 and 19 on the monitor 3, the area surrounded by a rectangle with these two points as diagonals is determined to be the area to be specially transmitted, and the address signals at those two points are read out addresses. The address generator 8 sends out the signal as a representative signal. Further, since the cursor generating section 10 generates a cursor signal, a rectangle indicated by a symbol 20 is displayed on the monitor 3 as an area to be specially transmitted.

In this way, an address signal representing an area to be specially displayed, an address signal representing an area to be specially transmitted,
The video signal stored in the video memory is displayed on the receiving side, but the parts that should be specially displayed are usually designated on a large area a, so the important parts on the screen are displayed in a large size at the designated location. Ru. At this time, if the video signal of the area to be transmitted is displayed as it is on the injured side, as shown in Figure 3 (2)), the islands between the pixels are close together, but the pixels actually displayed are The third
As shown in the figure ←], the intervals between displayed pixels are widened. Then, the CPU section on the receiving side interpolates between them and displays pixels that are not specified by the sent information. Therefore, even if the screen is enlarged and displayed, the image quality will not deteriorate.
