Optical compensation method for display screen, storage medium, and electronic device

An electronic device, comprising at least a processor and a memory storing a computer program, wherein the processor, when loading and running the computer program, is caused to execute instructions for:

• determining a refresh time of a to-be-compensated screen;
• determining an exposure time as N times the refresh time, wherein N is a positive integer;
• controlling a camera to shoot the to-be-compensated screen based on the exposure time;
• acquiring an original image of the to-be-compensated screen captured by the camera;
• identifying and analyzing luminance of pixels at each position in the original image based on a compensation algorithm to determine luminance information of each pixel in the original image;
• determining a compensation parameter based on the luminance information;
• and
• adjusting display parameters based on the compensation parameter to equalize the luminance of the pixels at each position in the original image;
• or adjusting input grayscale values corresponding to pixels with lower luminance based on the compensation parameter to increase the luminance of the pixels with lower luminance, so as to equalize the luminance of the pixels at each position in the original image.

A non-transitory computer-readable storage medium, storing a computer program, wherein the computer program, when loaded and run by a processor of an electronic device, causes the electronic device to execute instructions for:

• determining a refresh time of a to-be-compensated screen;
• determining an exposure time as N times the refresh time, wherein N is a positive integer;
• controlling a camera to shoot the to-be-compensated screen based on the exposure time;
• acquiring an original image of the to-be-compensated screen captured by the camera;
• identifying and analyzing luminance of pixels at each position in the original image based on a compensation algorithm to determine luminance information of each pixel in the original image;
• determining a compensation parameter based on the luminance information;
• and
• adjusting display parameters based on the compensation parameter to equalize the luminance of the pixels at each position in the original image;
• or adjusting input grayscale values corresponding to pixels with lower luminance based on the compensation parameter to increase the luminance of the pixels with lower luminance, so as to equalize the luminance of the pixels at each position in the original image.
