Abstract

PURPOSE:To always excellently display a video image on a window display screen even when the display position or the screen size of the window display screen is changed and to display the video image on the window display screen by optionally enlarging and reducing it. CONSTITUTION:The video image data (A) of one frame is stored in a dual port video RAM 3. After the display position and the screen size of the window display screen are set to an X direction FIFO (dual port serial access memory) 10 and a Y direction FIFO 11, address data that the access of the RAM 3 should be executed is written. Then, dot data among the data (A) corresponding to the specified variable power rate of an image read out of the RAM 3 by the address data and superimposed on the data displayed on a computer side. Then, it is displayed on a computer screen.
