Image corrector, display device including the same and method for displaying image using display device

1. An image corrector comprising:

a processor; and

a memory coupled to the processor, wherein the memory stores instructions that, when executed by the processor, cause the processor to:

determine a shift direction and a shift amount of an image corresponding to first image data;

divide the image along an axis of a total display area into a plurality of areas and, in accordance with the shift direction, to determine a first area of the plurality of areas as a reduction area, a second area of the plurality of areas as an enlargement area, and a third area of the plurality of areas between the first area and the second area; and

set second image data corresponding to the shift amount of the image corresponding to the first area such that the first area is reduced in size, the second area is enlarged in size, and the third area is neither reduced nor enlarged in size.

2. The image corrector as claimed in claim 1 ,

wherein the third area of the image is shifted in a direction towards a location of the reduction area in the enlargement area.

3. The image corrector as claimed in claim 1 , wherein the instructions further cause the processor to combine a portion of image data for displaying the third area and image data for displaying the first area to generate enlarged image data, the third area being between the first area and the second area.

4. The image corrector as claimed in claim 1 , wherein the instructions further cause the processor to set enlarged image data corresponding to the shift amount to image data to be input into the second area.

5. The image corrector as claimed in claim 1 , wherein the instructions further cause the processor to generate enlarged image data using a portion of image data for displaying the second area.

6. The image data as claimed in claim 1 , wherein the image is shifted from the enlargement area to the reduction area.

7. The image corrector as claimed in claim 1 , wherein a size of an image display area of the image is maintained to be the same as that of the image prior to the shift and that of the image after the shift.

8. The image corrector as claimed in claim 1 , wherein the instructions further cause the processor to receive frame data comprising a plurality of image data and to calculate an input number of the frame data.

9. The image corrector as claimed in claim 8 , wherein the instructions further cause the processor to determine a look-up table corresponding to the input number and to determine the shift direction and the shift amount using a value in the look-up table.

10. The image corrector as claimed in claim 1 , wherein the instructions further cause the processor to:

determine an x-axis shift direction and an x-axis shift amount of the image; and

determine a y-axis shift direction and a y-axis shift amount of the image.

11. The image corrector as claimed in claim 10 , wherein the instructions further cause the processor to determine the x-axis shift amount such that the image shifts along an x-axis by an amount that is less than a size of an image displayed in one pixel.

12. The image corrector as claimed in claim 10 , wherein the instructions further cause the processor to determine the y-axis shift amount such that the image shifts along a y-axis by an amount that is less than a size of an image displayed in one pixel.

13. The image corrector as claimed in claim 10 , wherein the instructions further cause the processor to determine the y-axis shift direction and the y-axis shift amount after determining the x-axis shift direction and the x-axis shift amount.

14. The image corrector as claimed in claim 10 , wherein the instructions further cause the processor to determine the x-axis shift direction and the x-axis shift amount after determining the y-axis shift direction and the y-axis shift amount.

15. A display device comprising:

a display panel comprising a plurality of pixels;

a processor; and

a memory coupled to the processor, wherein the memory stores instructions that, when executed by the processor, cause the processor to:

generate image data;

determine a shift direction and a shift amount of an image;

divide the image along an axis of a total display area into a plurality of areas;

determine a first area of the plurality of areas as a reduction area in accordance with the shift direction;

determine a second area as an enlargement area;

determine a third area between the first area and the second area; and

set image data, which is reduced to correspond to the shift amount, to image data for displaying the first area such that the first area is reduced in size, the second area is enlarged in size, and the third area is neither reduced nor enlarged in size.

16. The display device as claimed in claim 15 ,

wherein the instructions further cause the processor to:

receive frame data comprising a plurality of image data and to calculate an input number of the frame data,

determine a look-up table corresponding to the input number; and

use values contained in the look-up table to determine the shift direction and the shift amount.

17. The display panel as claimed in claim 15 , wherein the instructions further cause the processor to determine the shift amount such that the image is shifted by an amount that is less than a size of an image displayed in one pixel.

18. The display panel as claimed in claim 15 , wherein the image is shifted toward a location of the reduction area in the enlargement area, and wherein a size of a display area of the image prior to the shift is the same as a size of the image after the shift.

19. The display device as claimed in claim 15 , wherein the instructions further cause the processor to combine a portion of image data for displaying the third area between the first area and the second area and image data for displaying the first area to generate reduced image data.

20. A method for displaying images by a display device comprising a display panel comprising a plurality of pixels, and a processor, the method comprising:

generating, by the processor, image data;

receiving, by the processor, frame data comprising a plurality of image data, by an image corrector circuit;

calculating, by the processor, an input number of the frame data;

determining, by the processor, a look-up table corresponding to a result of the calculation, by the image corrector circuit;

determining, by the processor, a shift direction and a shift amount of an image using a value in a look-up table, by the image corrector circuit;

dividing, by the processor, the image along an axis of a total display area into a plurality of areas;

determining, by the processor, a first area as a reduced area of the plurality of areas, a second area as an enlarged area, depending on the shift direction, and a third area between the first area and the second area; and

setting, by the processor, reduced image data corresponding to the shift amount to image data for displaying the first area such that the first area is reduced in size, the second area is enlarged in size, and the third area is neither reduced nor enlarged in size.
