摘要

A tile image sequence 250 obtained by dividing a frame into a predetermined size is further divided into another predetermined size on an image plane to generate a voxel (for example, a voxel 252) (S10). If a redundancy in a space direction or a time direction exists, then data is reduced in the direction (S12), and sequences in the time direction are deployed on a two-dimensional plane (S14). Voxel images are placed on an image plane of a predetermined size to generate one integrated image 258 (S16). In a grouping pattern which exhibits a minimum quantization error, pixels are collectively placed in the region of each voxel image for each group (integrated image 262) (S18). The integrated image 262 after the re-placement is compressed in accordance with a predetermined compression method to generate a compressed image 266 and reference information 264 for determining the position of a needed pixel (S20).
