Abstract
A color adjustment method and device are provided. The color adjustment method comprises: 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; and performing a gamma correction process on the 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.
