Abstract
The present disclosure relates to a method and a device for compensating for a luminance deviation. A difference in pixel value of the image capturing device between a first pixel and a second pixel in the screen and a difference in gray scale level between first and second gray scale levels are derived from a captured image at the first gray scale level and a captured image at the second gray scale level which include pixel values of the image capturing device. A pixel value for the second pixel is calculated from the captured image at the first gray scale level.
