Abstract:
A gamma correction method applied to a display screen to be debugged includes: for a color of the display screen to be debugged, arranging a plurality of reference points, arranging at least one transition point between two adjacent reference points, and obtaining a brightness adjustment curve representing a corresponding relationship between a brightness adjustment value and a gamma band according to the plurality of reference points and the at least one transition point. Each gamma band represents a set of register values corresponding to gray scales of the color at the brightness adjustment value corresponding to the gamma band.
