Patent ID: 8767001

Claim:
A method of compensating data, the method comprising: providing a look-up table divided into a first area, a second area and a boundary area between the first and second areas, said first, second and boundary areas being generated by a first previous reference value, a second previous reference value greater than the first previous reference value, a first current reference value and a second current reference value less than the first current reference value; and generating compensation data for a current frame based on whether grayscale data of said current frame and of a previous frame satisfy a condition for one of the first, second or boundary areas, wherein the condition for the first area is that grayscale data of the previous frame has a value less than the first previous reference value and the grayscale data of the current frame has a value greater than a first current reference value, the condition for the second area is that grayscale data of the previous frame has a value greater than the second previous reference value and grayscale data of the current frame has a value less than a second current reference value, or that grayscale data of the previous frame has a value greater than the second previous reference value and grayscale data of the current frame has a value greater than a second current reference value, or that grayscale data of the previous frame has a value less than the second previous reference value and grayscale data of the current frame has a value less than a second current reference value, and the condition for the boundary area is that grayscale data of the previous frame has a value between the first and second previous reference values, or that grayscale data of the current frame has a value between the first and second current reference values, the boundary area being between the first and second areas.
