Image display luminance compensation method, computer device, and storage medium

A computer device comprising a processor and a memory storing a computer program, wherein the processor, when executing the computer program, implements:

• obtaining camera exposure times of respective grayscale images to be captured under a maximum target luminance;
• controlling a photographing device to capture the grayscale images according to the camera exposure times, and obtaining luminance data of each of the grayscale images captured;
• determining a target region in each of the grayscale images according to the luminance data of each of the grayscale images, the target region being a region to be subjected to luminance compensation;
• calculating grayscale compensation values of the target region according to the luminance data of each of the grayscale images;
• and
• performing luminance compensation on the target region according to the grayscale compensation values of the target region;
• wherein after obtaining the luminance data of each of the grayscale images captured, the method further comprises:
• generating grayscale luminance curves of the grayscale images according to the luminance data of the grayscale images;
• verifying validity of the luminance data of the grayscale images according to the grayscale luminance curves of the grayscale images to determine a verification result;
• performing the step of determining the target region in each of the grayscale images according to the luminance data of each of the grayscale images when the verification result is valid;
• and
• re-capturing the grayscale images when the verification result is invalid.
