Claim One:
1. A method for compensating images in a display device, the method comprising: decoding an incoming image signal with a decoder; storing the decoded image signal in a memory as image blocks; and processing the stored image blocks with a processor, the step of processing including forming a process window that overlaps with two adjacent image blocks, calculating distortion ratios of image blocks based on a gray value difference between each of a plurality of pairs of pixels in the process window that face each other at a boundary between the two adjacent image blocks and the average of differences between gray values of other adjacent pixels in the process window that do not face each other at the boundary between the two adjacent image blocks, setting compensation parameters based on the calculated block distortion ratios, and calculating distortion compensation values of the two adjacent image blocks by multiplying a specific value and the set compensation parameters, the specific value obtained by substituting the gray value difference into a dissipation function; and compensating the two adjacent image blocks according to the calculated distortion compensation values.
