Claim 12:
13. The terminal device of claim 12, wherein the processor is further configured to perform operations comprising:
determining whether the luminance ratio is smaller than a preset luminance ratio;
in response to determining that the luminance ratio is more than or equal with the preset luminance ratio, performing a logarithmical calculation on the luminance ratio based on a preset logarithmic function, to obtain a luminance compensation value;
determining whether the chromaticity ratio is smaller than a preset chromaticity ratio; and
in response to determining that the chromaticity ratio is more than or equal with the preset chromaticity ratio, determining a chromaticity compensation value based on the first chromaticity coordinate and the second chromaticity coordinate.
