Abstract:
1. A method of compensating luminance of a display module for sequentially displaying a reference frame and a current frame of the display module, the method compensating the luminance of a de-interlaced pixel in a current block of the current frame with reference to a reference block of the reference frame, the method comprising the steps of: calculating an average luminance of the current block and an average luminance of the reference block; and adjusting the luminance of the de-interlaced pixel by an amount that is proportional to a luminance difference between the current block and the reference block; wherein the average luminance of the current block is determined by averaging the luminance of all received pixels positioned on odd/even scan lines, excluding other to-be-de-interlaced pixels positioned on even/odd scan lines, in the current block, while the average luminance of the reference block is determined by averaging the luminance of all the pixels in the reference block, and the luminance of the de-interlaced pixel is determined by a reference pixel in the reference block, the reference pixel corresponding to the de-interlaced pixel, plus the luminance difference.
