Abstract A visual recognition device receives video signals representing an object to be recognized from a video camera, converts the video signals to a two-valued input pattern, and compares the input pattern with a standard pattern to recognize the object. The recognition device includes an auxiliary computing unit which carries out a predetermined auxiliary computation during a horizontal scan period of the video camera, in accordance with the state of the input pattern; a main computation unit for carrying out, during a vertical return scan blanking period of the video camera, a main computation based on computation results of the auxiliary computation unit; and a recognition unit for recognizing the input pattern with respect to the standard pattern based on computation results of the main computation unit with respect to the patterns.
