Abstract

The embodiment of the present invention discloses a brightness adjustment method, which is characterized in that the method includes: obtaining the brightness value corresponding to each pixel in the image to be processed and the total number of pixels in the image to be processed; The brightness value of a pixel, determine the number of pixels corresponding to each brightness value; based on the number of pixels corresponding to each brightness value and the total number of pixels in the image to be processed, adjust the Processes the brightness of pixels in an image. The embodiment of the invention also discloses a brightness adjustment device and a computer-readable storage medium, which solves the problem of uneven brightness distribution of pictures in the prior art.

Description

technical field [0001] The present invention relates to image processing technology in the communication field, in particular to a brightness adjustment method, device and computer-readable storage medium. Background technique [0002] With the development of science and technology, the functions of smart terminals are becoming more and more powerful; and, with the improvement of people's living standards, the use of smart terminals is becoming more and more popular. For users, the camera function of smart terminals such as smart phones is the most commonly used. [0003] However, the distribution of brightness values ​​of pixels in pictures taken by existing smart terminals is not uniformly distributed; the distribution of brightness values ​​of pixels in some pictures is concentrated in one or two intervals, so that As a result, the brightness of the entire picture is not obvious, which in turn affects the clarity of the picture. Contents of the invention [0004] In v...
