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 5):
The method of  claim 1 , wherein determining the gray scale distribution information of the picture to be displayed comprises:\n analyzing a histogram of the picture to be displayed; determining a plurality of gray scale ranges in the picture to be displayed; and determining a pixel number ratio of each of the plurality of gray scale ranges in the picture to be displayed according to the histogram to obtain the gray scale distribution information of the picture to be displayed, wherein the pixel number ratio of the gray scale range is a ratio of a number of pixels having a gray scale within the gray scale range in the picture to be displayed with respect to a total number of pixels in the picture to be displayed.
