<p>The system consists of a main CPU (1), a data memory (2), a bus medication circuit (3), a CPU for image operation (4), a frame memory (5), a gate (6), a buffer memory for image operation (7), a monitor (8) and a camera (9). Image data are stored in the frame memory (5) and displayed on the monitor (8). When the display of a part of another image is requested, that part of the first image is temporarily saved in the buffer memory for image operation (7) and the second image is transferred into the frame memory (5) and displayed. When the second image is erased, the first image saved in the buffer memory (7) is restored to the frame memory (5) and displayed. This image data transfer is controlled by the CPU for image operation (4).</p> |
