Abstract

The present invention provides an image processing method, which includes: obtaining an original picture; determining a designated area in the original picture; generating a mask matrix for the designated area; and performing grayscale transformation on the original picture according to the mask matrix. ; and perform edge smoothing and overall equalization processing on the overall image of the grayscale transformed image. The invention also provides an image processing device. The above-mentioned image processing method and device can achieve the skin whitening effect of the people in the photo, and is simple and convenient to operate, bringing a better experience to users when processing photos and pictures.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to an image processing method and device. Background technique [0002] With the popularization of terminal products with cameras such as digital cameras, mobile phones, and tablet computers, people have more and more opportunities to take pictures, and there are also more and more occasions to use photos. For example, when you are in a place with a beautiful environment or just bought a new piece of clothing, people hope to share the place where you are and the appearance of wearing the new clothes with your relatives and friends, and you can take a photo of yourself with your mobile phone. And share it with others through social software, such as instant messaging products (QQ, WeChat, Skype, etc.). [0003] However, due to factors such as light, camera equipment, and shooting angles, the effect of the photo after shooting, especially the skin color part, is often unsat...
