Method and structure for generating picture compensation signal, and restoring system

A structure for generating a picture compensation signal, comprising:

• a calculating module, configured to set a grayscale percentage value and adjust luminance of a display device;
• a luminance difference detection module, configured to obtain a luminance difference value according to a highest grayscale center luminance value and a corresponding a region luminance value, and a lowest grayscale center luminance value and a corresponding region luminance value;
• a difference determining module, configured to determine whether the luminance difference value is less than a default value;
• and
• a processing module, configured to replace the grayscale percentage value, and obtain a sampling grayscale according to the grayscale percentage value.

A restoring system, configured to provide a picture compensation signal to a display device, wherein the restoring system comprises:

• an image capturing device, configured to obtain a luminance value of the display device;
• a calculating structure, configured to calculate a sampling grayscale;
• and
