Abstract
Exposure adjustment methods and systems are provided. First, image data including a plurality of pixels is obtained. A plurality of sample regions is set based on respective pixels. A parameter calculation is performed according to a plurality of specific pixels in the sample regions to obtain a plurality of groups of adjustment parameters. At least one of the pixels is performed with a parameter adjustment according to the adjustment parameters.
