ABSTRACT:
A visual information processing apparatus which processes image data produced by a TV camera to detect the change in image with the lapse of time. The visual information processing apparatus comprises a circuit which generates the data of coordinates X and Y that represent a scanning position on the image, a memory for storing a plurality of microprograms, a control circuit which addresses an initial instruction of a microprogram corresponding to the coordinate Y when the coordinate X reached a particular value that is specified by an external unit, and a unit for processing the image data from said TV camera in accordance with a microprogram that is read out from said memory, wherein the same microprograms are periodically read out by bringing least significant several bits among the binary data which represents the coordinate Y to correspond to an initial address of each of the microprograms. With this visual information processing apparatus, the TV screen is divided into a plurality of blocks and a reduced number of microprograms are required for processing the image data.
