Abstract

Moving images are coded with reduced deterioration in the image quality while variations in the amount of code per frame are being reduced. A moving image coding apparatus includes a remaining picture number obtaining unit, an activity calculation unit, an intra MB determination unit, and a coding unit. The remaining picture number obtaining unit detects the temporal position of the current frame image, and determines the reset timing at which an intra refresh process is reset in a manner that the reset timing differs for each macroblock line (MBL). The activity calculation unit calculates an activity value for each macroblock (MB). The intra MB determination unit determines a MB to be set as an intra MB based on the activity value calculated by the activity calculation unit. The coding unit codes the MB set as an intra MB through an intra coding process.
