Patent ID: 8675741

Claim:
A method for improving image quality, the method comprising: generating a plurality of sub-frame images from a current frame image, wherein the plurality of sub-frame images comprise a first sub-frame image and a second sub-frame image; and determining whether the current frame image is a moving image or a still image based on a difference between a previous image and the current image; displaying the generated plurality of sub-frame images sequentially for one frame display time, wherein the plurality of sub-frame images are generated to be different from the current frame image if the current frame image is the still image, and the plurality of sub-frame images are generated to be equal to the current frame image if the current frame image is not the still image, and wherein if a part of the frame image is a still image, pixels in a part of the first sub-frame image and pixels in a part of the second sub-frame image, which correspond to pixels in the part of the frame image, have values which are different from pixel values of the part of the frame image.
