Abstract

An objective of the present invention is to reduce coding computation volume and decoding computation volume while alleviating coding efficiency degradation beyond conventional intra segmented image coding. A segmented image generation unit segments an inputted image to be coded into blocks of the same size and gathers pixels of the same relative location within each block generating segmented images which are respectively of the same size. An intra segmented image coding unit carries out segmented image coding for some segmented images. To code other segmented images a reference image selection unit selects a coded segmented image with a close pixel location in a source image as a reference image. A segmented image inter predict coding unit generates a predict image using the selected reference image and codes the segmented image to be coded by segmented image inter predict with a segmented image as a unit.
