Gamma correction method and apparatus, electronic device, and readable storage medium

Abstract

A gamma correction method and apparatus, electronic device and readable storage medium. The method comprises: controlling a first display area () to display a test picture (S); performing gamma correction on first display area to obtain first gamma correction data (S); according to first gamma correction data, controlling a second display area () to display the test picture (S); acquiring current display brightness corresponding to the test picture displayed in second display area (S); when current display brightness is the same as that corresponding to a preset pixel grayscale displayed in first display area, determining remapping parameters of second display area according to grayscale brightness corresponding to second display area when current display brightness is displayed and preset pixel grayscale (S); according to remapping parameters, compensating first gamma correction data to obtain second gamma correction data (S); according to second gamma correction data, controlling second display area to display (S).
