COLOR ADJUSTMENT METHOD AND DEVICE
First Claim
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; 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.
