PURPOSE:To ensure that desired frames are written in frame memories even if the operation timing of a memory switch is delayed by installing of many frame memories. CONSTITUTION:Many frame memories 191 to 194 are installed and image signals are sequentially written into the memories by frame, and desired frames are selected by a memory switch to read the image signals sequentially from frame memories 30. Since the many frame memories 191 to 194 are installed, it is ensured that the desired frames are written into the frame memories as long as the delayed operation timing of the memory switch 20 occurs within the frame. |
