Abstract
A luminance compensation method. According to the method, a central calibration point is acquired on the sampled image. A plurality of third calibration points is generated on the sampled image based on the central calibration point. The sampled image is divided into a plurality of regions to be corrected. A corrected position of each second calibration point in any one of the regions to be corrected is acquired for an initial position of each third calibration point in the region to be corrected. An affine transformation correction is performed on the sampled image based on the corrected positions of all the second calibration points and reference positions of the first calibration points corresponding to the second calibration points, so that a corrected image is acquired. And luminance data of a reference image is compensated to the sampled image.
