Color space mapping method, equipment, computer readable storage medium, and device

A non-transitory computer readable storage medium, wherein a color space mapping program is stored on the computer readable storage medium, the color space mapping program, when executed by a processor, implements the following operations:

• confirming data volume of original data, and determining a data extraction ratio according to the data volume;
• determining a preset order of extracting the original data according to the data extraction ratio;
• extracting the original data in the preset order, calculating feature data according to the extracted original data, and calculating a feature coefficient according to the original data and the feature data;
• generating a 3D pixel gray scale table according to the feature coefficient and the feature data;
• transmitting the 3D pixel gray scale table to a color processing area for storage, to allow a target TV terminal to read a stored data content of the 3D pixel gray scale table for image color mapping;
• and
• performing the image color mapping through the 3D pixel scale table.
