1. A saturation enhancement method performed by a display device comprising a processor, wherein the saturation enhancement method comprises:
converting, by the processor of the display device, a color space of an input image to obtain color data of color conversion;
expanding, by the processor of the display device, color saturation on the color data of the color conversion to obtain an expanded color data;
performing, by the processor of the display device, a gamma-based preprocess on the expanded color data to obtain a processed color data;
wherein the step of converting the color space of the input image to obtain the color data of the color conversion comprises:
acquiring, by the processor of the display device, RGB data of each pixel in an RGB space of the input image;
normalizing, by the processor of the display device, the RGB data and performing, by the processor of the display device, gamma correction on a normalized RGB data to obtain linear RGB data of the input image; and
converting, by the processor of the display device, the linear RGB data of the input image into LCH data in an LCH space;
wherein the step of converting the linear RGB data of the input image into the LCH data in the LCH space comprises:
converting, by the processor of the display device, the linear RGB data of the input image into XYZ data in an XYZ space;
converting, by the processor of the display device, the XYZ data into Luv data in a Luv space;
converting, by the processor of the display device, the Luv data into the LCH data in the LCH space.
