Abstract
A method for compensating luminance of a display device according to some embodiments of the present disclosure includes capturing an image of the display device, generating imaging data, primarily mapping display pixels of the display device and the imaging data so that a unit mapping area corresponding to the display pixels includes luminance values for image pixels of an imaging device, setting an offset value of the imaging data with respect to the display pixels so that a maximum luminance value among the luminance values is positioned at a center of the unit mapping area, secondarily mapping the imaging data according to the offset value with respect to the display pixels, calculating a representative luminance value, and setting a luminance correction value corresponding to the representative luminance value with respect to one of the display pixels.
