<P>PROBLEM TO BE SOLVED: To provide a moving picture encoding method and moving picture encoder capable of starting reproduction from an intra-coded picture in the middle of an image encoding signal, and further, capable of performing reproduction without error after the intra-coded picture, even in a case where an error occurs in a stream. <P>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 motion detection unit 101 for determining 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 Re 3 stored in memories 408 to 410 according to the number of referenceable pictures Num, which is the result of the counting by the counter unit 102. <P>COPYRIGHT: (C)2008,JPO&INPIT |
