Claim 2:
3. The correction method according to claim 1, wherein obtaining the interpolation step-size of the gray scale value of the sub-pixel in the second pixel value according to the gray scale values of the corresponding sub-pixels in the two first standard pixel values and the gray scale value of the sub-pixel in the second pixel value, includes:
obtaining a color temperature value corresponding to the second pixel value;
comparing the color temperature value corresponding to the second pixel value with the standard color temperature value;
set the interpolation step-size of the gray scale value of the sub-pixel in the second pixel value to (Nsc−Npr)/(Nex−Npr), in response to determining that the color temperature value corresponding to the second pixel value is greater than the standard color temperature value; and
set the interpolation step-size of the gray scale value of the sub-pixel in the second pixel value to (Npr−Nsc)/(Nex−Npr), in response to determining that the color temperature value corresponding to the second pixel value is less than the standard color temperature value,
wherein Nsc represents the gray scale value of the sub-pixel in the second pixel value; Npr represents a gray scale value of a corresponding sub-pixel in a previous first standard pixel value of the two first standard pixel values; Nex represents a gray scale value of a corresponding sub-pixel in a latter first standard pixel value of the two first standard pixel values.
