Abstract
PURPOSE: To perform coding of color picture with less amount of codes, by mitigating the limit relating to the coding time of picture, performing coding through the use of partial nature of picture in two dimension, and enabling the coding with high efficiency.
CONSTITUTION: The color picture 300 is scanned at the picture input section 301 and fed to the YIQ separation section 302, it is separated into Y,I,Q signals, and the plane corresponding to each component is sampled at the A/D conversion sections 303Y, 303I, 303Q and stored to the buffer memories 304Y, 304I, 304Q in the block unit as digital signal. The picture signal in two dimension distribution stored is split into two dimensional small blocks, and the signal of each video element belonging to the block each block is represented as a common plurality of signal values, the represented value is coded at the coding and processing sections 305Y, 305I and 305Q, each video element and the relation of correspondence with the represented signal close to it are coded, and the size of coding block of I, Q signals is made greater than the coding block of Y signal.
