摘要： PROBLEM TO BE SOLVED: To improve a compression rate by improving the efficiency of in-screen prediction by determining a processing sequence of each region with less information, since in conventional processing of macro blocks, shapes of the macro blocks and shapes of respective regions are not necessarily identical to each other and consequently conspicuous noise represented by block noise is generated, and reduction in the block noise is indispensable to improvement of the compression rate while keeping high image quality.
SOLUTION: A screen is divided by free shapes to generate region division information so that the block noise is made inconspicuous, and the region division information and region sequence information are linked. The processing sequence of divided regions is defined by a small data amount of information to improve the compression rate.
