More Information
Summary:Embodiments of the disclosure provide a color correction method and a color correction device. The method includes: obtaining native gamma information and native color point information of a display; obtaining target gamma information and target color point information of a target color space; obtaining a gamma correction parameter associated with the display based on the native gamma information and the target gamma information; determining a first pseudo gamma parameter based on the target gamma information; determining a second pseudo gamma parameter based on an inverse gamma operation of the target gamma information; determining a pseudo color space conversion matrix based on the native color point information and the target color point information; and updating a 3D lookup table of the display based on the first pseudo gamma parameter, the pseudo color space conversion matrix, and the second pseudo gamma parameter in sequence.
