A moving image coding apparatus has a blocking unit for dividing an image applied in units of frames into a plurality of blocks, a mode selection unit for selectively performing intra-frame coding for performing coding within the same frame, and inter-frame prediction coding for performing coding between frames, for each of the plurality of blocks, a self-image display unit for displaying the image, and a qualitative refresh map creation unit for creating a refresh map which sets a shorter refresh period for a block corresponding to a predetermined area on a display screen of the display means than the rest of the plurality of blocks. The mode selection unit performs the intra-frame coding at the refresh period set in the refresh map.
