ABSTRACT:
The position of a first pointer displayed on a display screen of a monitor display device is designated by a mouse. Data representing the position of a second pointer transmitted through an integrated digital service network 40 is received, and the position thereof is detected. In order to display the first and second pointers on the monitor display device, luminance data and chrominance data representing images of the pointers are generated by a character generator. The above data and image data stored in an image memory are synthesized in an image synthesizing circuit and an image obtained by the synthesis is applied to the monitor display device, so that the first and second pointers are displayed on the display screen of the monitor display device. Consequently, the first pointer designated by an operator of a terminal on the image data receiving side and the second pointer designated by an operator of a terminal on the image data transmission side are simultaneously displayed on the monitor display device.
