ABSTRACT:
The optimum predictive image is selected as follows for the entire area of an image sequence comprising a luminance signal expressing each pixel value, and a transmittance signal expressing the transparency of each pixel value, and described by the transmittance signal of the target image to be coded as the area to be coded. The target image to be coded is predicted from at least one template typical of the image sequence, thereby generating a first predictive image. The target image to be coded is also predicted from the image displayed chronologically before the target image, thereby generating a second predictive image. It is then determined whether the first or the second predictive image has the least difference to the target image to be coded, and the predictive image with the least difference is selected as the optimum predictive image.
