Abstract
An image coding apparatus calculates the activity of each macroblock. All the macroblocks of block lines are set as intra-candidate macroblocks (intra-candidate MBs) which are candidates for intra coding. Every other macroblock is set as an intra-candidate MB in block lines. One of the intra-candidate MBs in each block line, which has the minimum activity, is determined as an intra macroblock of a frame. The macroblock determined as the intra MB is changed from the intra-candidate MB to an intra-forbidden macroblock. After changing the setting of the intra-candidate MBs, intra macroblocks are determined for a frame inputted subsequent to the frame.
