ABSTRACT:
A picture data encoding circuit is constituted by a picture data buffer part storing the read picture data temporarily, an encoding circuit part for encoding the picture data per one line, a picture memory device part storing the encoded picture data, a picture data contracting part for decoding the encoded picture data as before and contracting it, a contracted picture data buffer part storing the contracted picture data temporarily, a signal switching part for signal transmissions of each part, and a signal processing part for processing signals of each part. One encoding circuit part is used in common in the reading of picture data and the data sending.
