Abstract
An image coding technique for suppressing degradation in image quality, in which the time and space where intra macroblocks appear are dispersed. A block count determination part determines the number of intra macroblocks to be allocated in each frame. A position determination part arranges the intra macroblocks at random positions in each frame. A coding part performs coding on the basis of the number of intra macroblocks to be allocated in a time direction, which is determined by the block count determination part, and the arrangement of the intra macroblocks in a spatial direction, which is determined by the position determination part, to thereby output compressed image data.
