PURPOSE:To transfer an animation efficiently with a simple configuration by dividing the picture into plural blocks and transferring the picture in an optimum mode in response to a rate of a change obtained based on a difference between blocks corresponding to between consecutive pictures. CONSTITUTION:A transfer picture is divided into a prescribed number of blocks, number of blocks of a fetched picture I(t) in which a difference between relevant blocks of both the picture I(t) and a picture I(t-1) at a preceding time is a prescribed value or over is obtained, the number is divided into three stages with the number of block as a rate of change, and the picture is transferred in a prescribed mode by an I encoder according to the stage discriminated by the M discrimination. Furthermore, for the blocks whose difference is a prescribed value or below, whether it is an animation stop blocks or still picture blocks are discriminated by the E discrimination, and the picture is processed and transferred respectively accordingly. Thus, the animation is efficiently transferred. |
