PURPOSE:To hold the continuity of respective images and to increase the number of the images of satisfactory quality by masking an image part except for a priority display image, transferring a synthesizing image, which has (n) sub- synthesizing images, to an image memory and priority-displaying the image in order. CONSTITUTION:A control part 19 of an image controller 10 instructs a transfer start to an image display control part 29 and after that, the respective LUT data of LUTs 15U, 15L, 16U and 16L are respectively transferred and stored through LUT receiving parts 27A and 27B of an image display device 20 to LUTs 24U, 24L, 25U and 25L through LUT transfer parts 17A and 17B. A main control part 19 stores mask image data of a memory 12 through an image synthesizing part 13 to a memory 14 and stored through a transfer part 18B and a receiving part 28B to a display priority memory 22. When the above- mentioned preparation processing is finished, while the respective sub-synthesized images of a memory 22 are displayed, the synthesized screen image having the (n) sub-screen images is transferred to an image memory 21 and the stored screen image is displayed to a display 231. |
