Abstract

A low-resolution image is displayed at higher resolution and afterimages are reduced. Resolution is made 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.

Claims (36)

1. A method for driving a display device, comprising:

performing a frame interpolation processing using a first image data and a second image data so that frame frequency can be made higher by the number of interpolated frames;

performing a first super-resolution processing on a third image data generated by the frame interpolation processing; and

performing a second super-resolution processing on the first image data,

wherein the frame interpolation processing and the second super-resolution processing are concurrently performed, and

wherein the first super-resolution processing is performed after the frame interpolation processing.

2. The method for driving a display device according to claim 1 , further comprising a step of performing converting an interlace image into a progressive image before the frame interpolation processing.

3. The method for driving a display device according to claim 1 , wherein at least one of the first super-resolution processing and the second super-resolution processing is performed in a part of a region in a screen.

4. A method for driving a display device, comprising:

performing a frame interpolation processing using a first image data and a second image data so that frame frequency can be made higher by the number of interpolated frames;

performing a first super-resolution processing on a third image data generated by the frame interpolation processing; and

performing a second super-resolution processing on the first image data,

wherein the frame interpolation processing and the second super-resolution processing are concurrently performed.

5. The method for driving a display device according to claim 4 , further comprising a step of performing converting an interlace image into a progressive image before the frame interpolation processing.

6. The method for driving a display device according to claim 4 , wherein the first super-resolution processing is performed in a part of a region in a screen.

7. The method for driving a display device according to claim 4 , wherein the second super-resolution processing is performed in a part of a region in a screen.

8. A method for driving a display device, comprising:

performing a frame interpolation processing using a first image data and a second image data so that frame frequency can be made higher by the number of interpolated frames;

performing a first super-resolution processing on a third image data generated by the frame interpolation processing;

performing a second super-resolution processing on the first image data; and

performing a local dimming processing after the second super-resolution processing,

wherein the frame interpolation processing and the second super-resolution processing are concurrently performed.

9. The method for driving a display device according to claim 8 , further comprising a step of performing converting an interlace image into a progressive image before the frame interpolation processing.

10. The method for driving a display device according to claim 8 , wherein at least one of the first super-resolution processing and the second super-resolution processing is performed in a part of a region in a screen.

11. The method for driving a display device according to claim 8 , wherein the local dimming processing is performed in a part of a region in a screen.

12. A method for driving a display device, comprising:

performing a frame interpolation processing using a first image data and a second image data so that frame frequency can be made higher by the number of interpolated frames;

performing a first super-resolution processing on a third image data generated by the frame interpolation processing;

performing a second super-resolution processing on the first image data;

performing a local dimming processing after the second super-resolution processing; and

performing an overdrive processing after the local dimming processing,

wherein the frame interpolation processing and the second super-resolution processing are concurrently performed.

13. The method for driving a display device according to claim 12 , further comprising a step of performing converting an interlace image into a progressive image before the frame interpolation processing.

14. The method for driving a display device according to claim 12 , wherein at least one of the first super-resolution processing and the second super-resolution processing is performed in a part of a region in a screen.

15. The method for driving a display device according to claim 12 , wherein the local dimming processing is performed in a part of a region in a screen.

16. The method for driving a display device according to claim 12 , wherein the overdrive processing is performed in a part of a region in a screen.
