Abstract
In a video coding apparatus coding a motion picture while switching a coding mode between an INTER coding mode and an INTRA coding mode, a motion information management part determines whether or not there is motion exceeding a prescribed threshold in an object in each region of m groups of blocks in each frame of the motion picture during a lapse of a prescribed time T from a prescribed point. On the basis of the result of this determination, a whole-group refresh part performs whole-group refresh (INTRA coding in one frame) on a group of blocks of a region having motion exceeding the threshold, and a dispersed refresh part performs dispersed refresh (INTRA coding in frames varying with the block) on a group of blocks of a region having no motion exceeding the threshold. Thus, appearance of a disturbance line is avoided and influence by a transmission error is eliminated in a short time while reducing increase of a coding quantity resulting from refresh.
