ABSTRACT:
A highly efficient coding apparatus is made for developing a prediction value from a value which is ahead in time, correlation. The apparatus comprises, first to M-th prediction circuits supplied with a picture signal of each of M areas which divide a picture composed of plural lines, each consisting of plural picture elements and generating output, respectively, the first prediction circuit having structure for selecting a prediction value generated by itself and an initial value, the prediction circuits other than the first prediction circuit having structure for selecting prediction values generated by themselves and other prediction values generated by the prediction circuits for processing divided areas adjacent in space and being ahead in time, whereby the other prediction circuits select other prediction values through the selecting structure at timing of processisng of picture element data which is closest to the border of the divided areas.
