To reduce the required amount of program codes when processing the whole image in a one-dimensional SIMD parallel image processing system having a smaller number of PEs than the number of pixels in the width direction of the image to be processed. A controller for controlling a PE array includes a command repetitive-execution part, which includes an operand converting part, a memory address converting part, and an operation code converting part. When a command fetching/decoding part reads and executes program codes stored in a program memory, the repetitive-execution part determines the program codes to cause the operand converting part, memory address converting part and operation code converting part to perform conversions in accordance with the command, thereby performing a repetitive execution of the one-command program description adaptive to a plurality of related pixels assigned to the PEs, whereby the program code amount can be reduced.
