Abstract
A low-resolution image is displayed at higher resolution and afterimages are reduced. Resolution is nude higher by super-resolution processing. In this case, the super-resolution processing is performed after frame interpolation processing is performed. Further, in that case, the super-resolution processing is performed using a plurality of processing systems. Therefore, even when frame frequency is made higher, the super-resolution processing can be performed at high speed. Further, since frame rate doubling is performed by the frame interpolation processing, afterimages can be reduced.
Claims2
A method for driving a display device, comprising:
- performing a frame interpolation processing by detecting motion using a first image and a second image, and generating a third image and a fourth image;
- and
- performing a first super-resolution processing of the third image to generate a fifth image;
- performing a second super-resolution processing of the fourth image to generate a sixth image;
- and
- performing an edge enhancement processing of the fifth image and the sixth image,
- wherein the first super-resolution processing and the second super-resolution processing are performed concurrently after the frame interpolation processing, and
- wherein the fourth image has a larger number of pixels than the first image.
