摘要:
An image coding, recording and reading apparatus generates a local decoded image which is used for motion compensation prediction at the same time when coding an original image to be coded so as to generate an original image coded stream, acquires a difference image which is a difference between the local decoded image and the original image to be coded, codes the difference image so as to generate a difference image coded stream, records the original image coded stream and the difference image stream generated thereby into a storage memory, and adds an original image and a difference image which are obtained by decoding both the above-mentioned coded streams read out of the storage memory, respectively, so as to generate an addition image.
