Abstract
Abstract In the terminal A, the input image "ABC" is displayed in a window 200A, with a rectangular frame 206A indicating the area of transmission. The image in the transmission area is enlarged, and transmitted to the terminal B after compression. In the terminal B, the input image "efghij" is displayed in a window 200B, with a rectangular frame 206B indicating the area of transmission. The image in the transmission area is enlarged, and transmitted to the terminal A after compression. In the terminal A, the image in a selected area (display area) of the received image is displayed in a window 202A. Also a window 204A displays the position and size of the display area within the entire received image. The transmission area of the input image and the display area of the received image can be enlarged, reduced or displaced.
