Claim One:
1. An image coding apparatus for successively coding pixel values constituting an image signal on the basis of pixel values of plural peripheral pixels positioned in the vicinity of a coding target pixel, comprising: blocking means for blocking an image signal comprising plural pixel values corresponding to a single image display region into blocks each comprising a prescribed number of pixels, and outputting, block by block, the prescribed number of pixel values constituting the image signal in each block; pixel value replacing means for replacing a pixel value of an uncoded pixel among the peripheral pixels with a pseudo pixel value that is obtained from a pixel value of a coded pixel among the peripheral pixels on the basis of a prescribed rule; and coding means for receiving the image signal comprising plural pixel values corresponding to each block, performing, for each block, a coding process in which the respective pixel values are successively coded on the basis of the pixel value of the coded pixel and the pseudo pixel value of the uncoded pixel, and outputting an coded image signal.
