PROBLEM TO BE SOLVED: To prevent the generation of losses in processing without exerting an adverse effect to picture quality. SOLUTION: When a plurality of image processing modules 28 are arranged as pipeline structure, a shared memory module 36 is arranged between two image processing modules 28. The shared memory module 36 provided with a shared buffer 38 can exclusively access without any loss the preceding image processing module 28 (A1) or the succeeding image processing module 28 (A2) without generating overlap between the writing of image data in the shared buffer 38 and the reading of image data from the shared buffer 38. Thereby even when a plurality of image processing modules 28 having respectively different processing speeds are arranged as the pipeline structure, waiting time for writing/reading of image data of respective image processing modules can be minimized and the processing speed can be improved as a whole.
