Patent ID: 8325164

Claim:
A display apparatus for presenting a moving image with less perceivable degradation, the apparatus comprising: display control means for dividing an input signal containing input frames of the moving image to be displayed into N output signals containing output frames, where N is an integer greater than 1, wherein: (1) the input signal has a frame rate of X frames/sec, (2) each output signal has a frame rate of X/N frames per second, and (3) each input frame corresponds to one and only one output frame, controlling the display of the moving image by causing display means to sequentially scan the output frames such that, after the scan of a first output frame is begun, the scan of each subsequent output frame is begun 1/X sec after the beginning of the scan of a previous output frame, wherein the output signal corresponding to the output frame that is scanned alternates sequentially, and controlling display to cause the display means to change a display of the moving image to an effective frame rate of 350 or 360 frames/sec when the moving image is a computer graphics image, where the effective frame rate is the sum of the frame rates of the output signals; and the display means for displaying the moving image at the frame rate on the basis of control of the display control means, in which a display of each pixel on a screen is maintained during each frame period.
