Abstract: The problem when the use range of images for use in intra-prediction is expanded is that the requirement for line buffer size increases depending on the range of expansion, and, in order to solve this problem, the use range of imaged for use in intra-prediction is adaptively controlled. The intra-prediction apparatus 100 of the present invention has, a control section 115 that controls, based on the relationship between the position of a candidate image for use in intra-prediction for a block to be processed and the position of the unit where the block to be processed belongs, the partial range for use for intra-prediction beyond the end portion of the unit in a predetermined direction in the use range of the image for use for intra-prediction to be equal to or less than a predetermined maximum range.
