Patent ID: 7844128

Claim:
An image display method comprising: inputting an image signal that is a YCbCr signal to a frame converter; multiplying a frame frequency of the image signal by the frame converter so that one frame is divided into a plurality of sub-frames including at least a first sub-frame and a second sub-frame; outputting a first original signal that corresponds to the first sub-frame and a second original signal that is identical to the first original signal and corresponds to the second sub-frame; reducing a high-spatial frequency component of the first original signal, thereby generating a first image signal; increasing a high-spatial frequency component of the second original signal, thereby generating a second image signal; converting the first image signal and the second image signal into RGB signals; and displaying the first sub-frame based on the first image signal that has been converted into the RGB signal, and the second sub-frame based on the second image signal that has been converted into the RGB signal.
