A gamma correction method is disclosed that performs gamma correction for a display device. A plurality of correction matrices respectively corresponding to a plurality of spectrums of different test display devices is obtained. A spectrum of the display device is measured. A correction matrix corresponding to the spectrum of the display device is selected from the plurality of correction matrices. Tristimulus data of the display device are measured and the measured tristimulus data are converted into perception tristimulus data by using the selected correction matrix. The gamma correction for the display device is performed based on the perception tristimulus data.

Gamma correction method, gamma correction system and display device

A head mounted display device includes: a display module displaying an image; a calculator including an adaptive luminance calculator that scans a first image based on a predetermined viewing angle and calculates a first adaptive luminance of the first image, and a discomfort luminance calculator that calculates a first discomfort luminance based on the first adaptive luminance according to an equation that models a relationship between the first adaptive luminance and the first discomfort luminance at which a user perceives discomfort; and a luminance controller that controls a dimming level of the display module to be equal to or less than the first discomfort luminance.
