Abstract

PURPOSE: To make it possible to segment partially picture data with high efficiency by making information density high and shortening an access time through coding with each line completed.
CONSTITUTION: Unit 1 is equipped which stores picture data, obtained by dividing two-dimentional picture data binary-coded into segments of the n-number lines from its head line and by coding the 1st line of each segment with one line completed and remaining lines on a segment unit with lines correlative, and data in the head address of each segment. Further, parameter arithmetic unit 2 for partial pictures, segmentation unit 3 which outputs picture data with the head address obtained by units 1 and 2, decoder 4, and unit 5 which supplies data to picture output unit 6 by receiving the head line are provided, so that coding will be attained from the head line with any one line completed.
