IMAGE CODING APPARATUS, IMAGE DECODING APPARATUS AND METHODS THEREOF

摘要

PROBLEM TO BE SOLVED: To provide an image coding method and image decoding method for remarkably improving coding efficiency in comparison with the prior art, in coding a still image.

SOLUTION: The image coding apparatus according to the present invention includes: a similar image search unit 201 which searches for at least one second still image which is similar to a first still image from a set of images; a coding processing unit 202 which generates a predictive image for the first still image using the at least one second still image as a reference image, and codes the difference between the first still image and a predictive image; and a reference image information processing unit 204 which adds information which indicates the location of at least one of the second still image to the bit stream.
