Abstract
This specification discloses a method of using locality statistics characteristic to enhance gamma corrections. Using the property that the color values of nearby digital image pixels are close to one another, the cache queue operation model is employed to partly replace the time-consuming table mechanism in the gamma correction procedure. The disclosed method first establishes a cache queue and then captures digital image pixels. According to the extracted digital image pixels, gamma correction values are searched to satisfy the cache queue. Finally, the gamma correction values corresponding to the digital image pixels are stored.
