Abstract
There is provided a method of displaying an image on a display device, the method including moving an image displayed at an image display region of the display device, and reducing a first region and enlarging a second region, the first and second regions included in the image, wherein the image has a smaller size than the image display region.
Claims26
An image corrector comprising:
- a frame counter configured to calculate frame information corresponding to a frame number of first image data based on a control signal;
- corresponding to a frame number of first image data based on a control signal;
- a movement amount determiner configured to determine an X axis movement direction and an X axis movement amount corresponding to the frame information and with reference to a first look-up table, the first look-up table mapping the frame information to the X axis movement direction and the X axis movement amount;
- an X axis shift determiner configured to determine an X axis black data amount corresponding to the frame information and with reference to a second look-up table, the second look-up table mapping the frame information to the X axis black data amount;
- an X axis area setter configured to set a first X axis area and a second X axis area each comprising a plurality of sub-areas such that the sub-areas of the first X axis area correspond to those of the second X axis area by using the X axis movement amount, the X axis black data amount, an X axis image scaling ratio, and an X axis internal scaling ratio;
- and
- an X axis data calculator configured to calculate pixel data of second image data in each of the sub-areas of the second X axis area by using pixel data of first image data in each of the sub-areas of the first X axis area.

A display device comprising:
- a display panel;
- an image corrector configured to correct first image data;
- and
- a display driver configured to control the display panel such that an image corresponding to image data corrected by the image corrector is displayed on the display panel by using the corrected first image data,
- wherein the image corrector comprises:
- a frame counter configured to calculate frame information corresponding to a frame number of first image data based on a control signal;
- a movement amount determiner configured to determine an X axis movement direction and an X axis movement amount corresponding to the frame information and with reference to a first look-up table, the first look-up table mapping the frame information to the X axis movement direction and the X axis movement amount;
- an X axis shift determiner configured to determine an X axis black data amount corresponding to the frame information and with reference to a second look-up table, the second look-up table mapping the frame information to the X axis black data amount;
- an X axis area setter configured to set a first X axis area and a second X axis area each comprising a plurality of sub-areas such that the sub-areas of the first X axis area correspond to those of the second X axis area by using the X axis movement amount, the X axis black data amount, an X axis image scaling ratio, and an X axis internal scaling ratio;
- and
- an X axis data calculator configured to calculate pixel data of second image data in each of the sub-areas of the second X axis area by using pixel data of the first image data in each of the sub-areas of the first X axis area.
