PURPOSE:To drastically shorten a filtering processing time by attaining memory access by a hardware configuration. CONSTITUTION:In an image processing system for executing parallel processing in each picture element based upon row parallel type local operation, the terminal address is connected to the leading address. The addressed of a finite length endless type slit memory 4 capable of storing the necessary number of data in a column to be processed are pointed out by a base pointer 1 and a reference pointer 2, the contents of the base pointer 1 are changed one by one by an external controller in each change of a row to be processed and the leading address is cleared following the terminal address. Simultaneously the contents of the pointer 1 are written in the pointer 2, and simultaneously with the specification of the address of the slit memory 4 by the pointer 2, the contents of the pointer 2 are changed only by '1' and the area of the memory 4 corresponding to the mask size of a filter is successively accessed by the pointer 2. |
