Abstract

The invention relates to an image processing method and an image processing device. According to the image processing method, the gray value of each pixel point of a local image is firstly acquired; and then the gray value of each pixel point of the local image is adjusted according to a preset gray value adjusting number, thereby realizing a purpose of increasing contrast of the gray value of each pixel point. When an image is processed according to the image processing method, after the local image is determined, the gray value of each pixel point is adjusted according to the preset gray value adjusting number, and a required effect of a user can be obtained without multiple adjustment by the user. The image processing method realizes requirement for short time and simple processing process.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method, device and terminal. Background technique [0002] With the widespread application of technologies such as Selfie and photo sharing, users often need to process images to achieve image beautification. [0003] At present, when using related technologies to process images, the images to be processed are usually stored in a terminal device in advance, such as a mobile phone, and the images are processed under the user's operation on the terminal. For example, when the contrast of human eyes in an image needs to be adjusted, the terminal device adjusts the contrast of human eyes according to the contrast information input by the user. [0004] However, the inventor found in the research process that when processing images in related technologies, the user often needs to input contrast information multiple times and adjust the contrast mu...
