ABSTRACT:
Binary image data is obtained from image data including a number plate of a vehicle which is picked up by a TV camera. Contrast image data of vertical and horizontal components are obtained, respectively, from the binary image data. An image having a continuous region whose size or area falls outside a predetermined range is erased. Subsequently, the vertical and horizontal contrast image components are combined with each other.
