Abstract
A coding circuit codes present image data of a pixel which is received as raster data and a delay circuit stores a coded image data for one frame period and outputs one-frame preceding image data of the pixel in accordance with an input of the coded image data. First and second decoder circuits decode coded image data and one-frame preceding coded image data, respectively, a variation-amount calculation circuit calculates variation-amount data of both decoded image date, and an one-frame preceding image reproduction circuit reproduces one-frame preceding reproduced image data. An image date correction circuit generates corrected present image data on the basis of the present image data and the one-frame preceding reproduced image data.
