Claim 15:
16. The non-transitory computer-readable storage medium according to claim 15, wherein, when the computer-readable instructions are configured to cause the processor to perform calculating the dark channel value of each pixel according to the first pixel value of each pixel of the first image, the computer-readable instructions are configured to cause the processor to perform:
obtaining a blue-light brightness value, a red-light brightness value, and a green-light brightness value respectively from the first pixel value of each pixel of the first image;
selecting a minimum brightness value from the blue-light brightness value, the red-light brightness value, and the green-light brightness value as a candidate brightness value of each pixel;
determining all pixels located in a preset pixel range as neighborhood pixels for each pixel; and
selecting a minimum candidate brightness value from candidate brightness values of the neighborhood pixels as the dark channel value of each pixel.
