Patent ID: 8040354

Claim:
An image processing device for controlling a display device to display a plurality of frame or field images making up a moving image at frame or field intervals, the image processing device comprising: 4×N (N: an arbitrary natural number) quadrant memories, each associated with one of 4×N types of quadrant images into which each of the frame or field images is divided; a separation section adapted to separate a moving image signal for the moving image into a series of 4×N frame or field image signals, each of which is associated with one of 4×N successive frame or field images to be displayed successively in time; a timing control section adapted to control a timing of each of the 4×N frame or field image signals, which are separated by the separation section, to be sequentially delayed by the frame or field interval, the timing control section being further adapted to control quadrant parts of the 4×N frame or field image signals, each of which quadrant parts is associated with one of the 4×N types of the quadrant images, to be sequentially output in a predetermined order, each of the 4×N frame or field image signals being output in a time-expanding manner over a period equal to 4×N times the frame or field interval; an assignment section adapted to assign and feed each of the quadrant parts of the 4×N frame or field image signals, which is output under the control of the timing control section, to a corresponding one of the 4×N quadrant memories which is associated with the type of the quadrant parts being output at that point in time; and an output control section adapted to control each of the 4×N frame or field images to be displayed on the display device in a display order, by reading from the 4×N quadrant memories and outputting to the display device at the frame or field intervals, the quadrant parts of the 4×N frame or field image signals, each of which quadrant parts is associated with one of the 4×N types of the quadrant images into which each of the frame or field images to be displayed is divided.
