PROBLEM TO BE SOLVED: To solve the problems of a development period, quality and flexible coping with specification change since there is no management means for performing data handling in common to the configurations of image processing modules and individual data handling is performed respectively, though there are various different configurations depending on whether or not DMA transfer is possible / whether the image processing module is hardware or software / whether or not a processing unit is the same or the like in the case of delivering data via a buffer (ring buffer) connecting the image processing modules. SOLUTION: When the image processing module side which performs write to the buffer connecting the image processing modules reports the number of write lines and the image processing module side which performs read reports the number of read lines by a band unit, the lines of non-processed data are inspected inside the buffer connecting the image processing modules at the timing, and a read trigger function, a write wait function and a write restart function registered beforehand are executed.
