PURPOSE:To speed up and simplify a processing by preventing the switching of reading and writing data in line memories while the processing of one line terminates and eliminating the read and write action of duplicated picture data from the line memory. CONSTITUTION:The latest picture data in picture data which are sequentially inputted in units of one scan line is written into the latest data storage area of a processing register 2, and it is simultaneously written into the line memory which stores the oldest picture data among the line memories 1. Storage picture data in the line memories except for the line memory storing the latest picture data among the line memories storing the latest picture data in the line memories 1 is written into the other storage areas except for the latest picture data storage area of the processing register 2 in a time-sequential array state with the latest picture data as a reference. |
