ABSTRACT:
An apparatus for processing a block of image data at a high speed, in which two items of data consecutive in data scan are simultaneously written in different memories and are processed as a set of data having a valid portion and an invalid portion and in which the subsequent process is differentiated depending on the frequency of occurrence of the data to suppress any increase in the scale of the circuit and to increase the speed of the same.
