Face-based tone curve adjustment

Abstract:

The technology disclosed herein provides a method of providing face-based tone curve adjustment to improve global and local contrast and brightness enhancement. In one implementation, the method includes determining a light level of an image captured by a camera, determining a contrast level of an image captured by a camera, comparing the light level and the contrast level to one or more of a plurality of thresholds, and based on the result of the comparison, selecting an advance intelligent global brightness contrast enhancement (AIGBCE) curve to the image.
