DYNAMIC IMAGE ENCODING INSTRUMENT, ITS METHOD AND PROGRAM, DYNAMIC IMAGE DECODING INSTRUMENT, AND ITS METHOD AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a dynamic image encoding instrument and its method and program which reduces a volume of calculation for encoding dynamic images and improver an encoding efficiency when the dynamic images are encoded through a motion-compensated prediction method.

SOLUTION: The dynamic image encoding instrument 1 is equipped with a reference image searching means 16 which searches images highly correlative to the target images to encode among encoded images stored in an encoded image storage 15a on the basis of camera information set correspondent to each image when the dynamic images are photoed, the searched images are made to serve as reference images, and the dynamic images are encoded on the basis of the reference images through a motion-compensated prediction method.
