PURPOSE:To display plural moving images without a frame omission and to plot a figure/character on a moving window and to take out the image from the moving window by using a data transfer means and an address control information switching means. CONSTITUTION:By the data transfer means, a window-b 119 is displayed as a sub window of the window-a 117 in the taking out of the image of the window-a 117, and when a frame memory where the window-b 119 belongs is different from the frame memory belonging to the window-a 117, the image data of the window-b 119 are transferred to the frame memory A 116. By the address switching means, when the moving image is displayed to the window-c 211, when the frame memory C 210 where the window-c 211 belongs is different from the memory D 212, the address of the frame memory referred in the plotting to the window and the address of the frame memory with which a window- c information control part 214 is provided are switched from the memory C 210 to the address of the memory D 212. |
