Abstract:
A method and a device for enhancing contrast are provided. According to an example, the method includes: determining gray scale distribution information of a picture to be displayed on a mobile device when the mobile device operates in a preset display mode, where, in the preset display mode, the mobile device has a screen luminance that is lower than a preset luminance threshold; determining a contrast adjustment curve of the picture to be displayed according to the gray scale distribution information; and enhancing contrast of the picture to be displayed according to the contrast adjustment curve.

Claim (Index 6):
The method of  claim 5 , wherein determining the contrast adjustment curve of the picture to be displayed according to the gray scale distribution information comprises:\n determining at least one of the gray scale ranges as a dominant gray scale range, wherein the at least one of the gray scale ranges has the pixel number ratio that is greater than a preset ratio threshold; and determining the contrast adjustment curve of the picture to be displayed according to the dominant gray scale range, wherein a horizontal axis of the contrast adjustment curve represents an input gray scale, a vertical axis of the contrast adjustment curve represents an output gray scale, and a curve slope of the contrast adjustment curve in the dominant gray scale range is greater than a curve slope in a non-dominant gray scale range.
