ABSTRACT:
There is provided a coding apparatus and method for hierarchically coding an image, in which a number of consecutive lines of image data representing pixels of the image are entered line by line. Reduced image data representing pixels of a reduced image based on the entered image data are formed. A determination is made in parallel with the formation of the reduced image data as to whether or not image data of an object pixel to be coded can be predicted from the reduced image data and from image data representing surrounding pixels of the entered object pixel. The entered image data are coded in accordance with the determination result.
