Abstract
A device for masking video data for character recognition, pattern recognition and other applications is disclosed. Pixel data stored in an image memory are two-dimensionally accessed by an X direction counter and a Y direction counter. At each time of access, pixel data read out are serially shifted by a first shift register which comprises flip-flops. Outputs of the first shift register are shifted by second shift registers which also comprise flip-flops, in synchronism with the first one of memory read signals.
