1. A color adjustment method, comprising:

  • obtaining frame data from a frame buffer;

    mapping the frame data from an original color space to a linear original color space via a de-gamma correction process, so as to obtain frame data in the linear original color space;

    mapping the frame data in the linear original color space to a linear target color space, so as to obtain frame data in the linear target color space;

    obtaining a color correction matrix of a target device, the color correction matrix being a deviation matrix obtained in the target color space according to deviations between color data of the target device and standard color data;

    correcting the frame data in the linear target color space by using the color correction matrix, so as to obtain corrected frame data in the linear target color space; and

    performing a gamma correction process on the corrected frame data in the linear target color space by using a target gamma coefficient, so as to obtain frame data in a target color space.
