Image processing for improving image quality

An electronic device, comprising:

• a processor;
• and
• a memory configured to store instructions that when executed by the processor cause the processor to perform operations, the operations comprising:
• adjusting an original luminance parameter of a pixel point in an image based on a luminance adjustment strategy to obtain an adjusted luminance parameter;
• determining a luminance change parameter of the pixel point according to the original luminance parameter and the adjusted luminance parameter, wherein the luminance change parameter is configured to represent a changing degree of the adjusted luminance parameter relative to the original luminance parameter;
• and
• adjusting an original saturation parameter of the pixel point based on the luminance change parameter to obtain an adjusted saturation parameter, so as to compensate for a saturation of the pixel point, wherein adjusting the original saturation parameter of the pixel point to obtain the adjusted saturation parameter comprises:
• determining a saturation protection weight based on the original saturation parameter,
• determining a saturation gain parameter based on the luminance change parameter;
• and
• determining the adjusted saturation parameter based on the saturation gain parameter, the saturation protection weight, and the original saturation parameter, wherein the saturation protection weight is configured to correct the saturation gain parameter.
