Abstract

The invention discloses an image processing method and device. The image processing method comprises steps that an original image is acquired; skin color detection on image pixels of the original image is carried out, and original skin color pixels of the original image are determined; an average value of characteristic parameter values of the original skin color pixels is calculated; according to a difference value of a preset standard average value and the average value acquired through calculation, a characteristic parameter value of each image pixel of the original image is corrected, the standard average value is acquired through calculation according to characteristic parameter values of standard skin color pixels of a preset standard image; an original image after correction is outputted. The method is advantaged in that image excessive exposure or darkness probability is reduced, a skin color of the image can be made to be closer to a natural real skin color of the user, and image quality is improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method and device. Background technique [0002] With the continuous development of social media, photos are gradually replacing text and become the main content way for users to record life details, among which self-portraits are mostly taken. Most of today's mobile phones, tablet computers and other terminal devices are equipped with front-facing cameras, making self-portraits more convenient, and self-portraits can be taken anytime, anywhere. When the existing camera technology processes photos, it generally automatically adjusts the aperture according to the ambient light, so as to obtain an exposure that matches the current ambient light. [0003] During the research and practice of the prior art, the inventors of the present invention found that when users take selfies, due to the wide variety of light conditions, the interference of li...
