ABSTRACT:
An averaging circuit for sequentially calculating an average of an original pixel data and a delayed pixel data to output a correction data and a multiplexer for selecting one of the pixel data and the correction data cooperate with each other, under control of a timing generator for generating a control signal, to output a pixel data on a contracted picture with a reduced distortion, permitting use of a relatively small-scale circuit.
