MOVING PICTURE ENCODING METHOD AND MOVING PICTURE DECODING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a moving picture encoding method and a moving picture decoding method or the like that can reproduce pictures starting with a processing subjected to intra-picture encoding on the way of image encoded signals and can reproduce a stream after the picture subjected to intra-picture encoding even on the occurrence of an error in the stream.

SOLUTION: A moving picture encoder 1 comprises: a counter unit (102) for counting the number of pictures starting with the picture subjected to intra- picture encoding; and a moving detection unit (101) for detecting a reference picture having the smallest intra-picture difference by comparing a picture signal Vin with only the reference pictures after the start of intra-picture encoding among a reference picture Ref1, a reference picture Ref2, and a reference picture Ref3 stored in memories 408 to 410 according to the number of referencable pictures Num, which is the result of the counting by the counter unit 102.
