ABSTRACT:
A color picture reading system including a correction circuit for correcting the output signal to eliminate color noise. In color picture reading systems the image of a picture element is optically separated into two or more color signals. Due to errors in the mounting position of optical sensors, color noise in the form of a color signal being erroneously present in the optical output occurs at the boundary of a color change in the picture. A correction is made by detecting the color signals resulting from the scanning of neighboring picture elements and deciding upon the correctness of a given color signal based upon the continuity of color information from the surrounding picture elements.
