Problems solved by technology

[0005] For this reason, the first purpose of the present invention is to propose a white balance processing method for images, which solves the problem of choosing a white balance algorithm in a way set by the user, which may easily lead to a mismatch between the white balance algorithm and the actual scene, resulting in a white balance processing effect. poor technical issues

Abstract

The invention discloses a white balance processing method and device of an image and a terminal device. The white balance processing method comprises the steps of calculating a first gain value of the image based on a human face white balance algorithm which is used for adjusting the human face in the image into a skin color; calculating a second gain value of the image based on a gray world algorithm; judging whether the first gain value and the second gain value are similar; if the first gain value and the second gain value are similar, carrying out white balance processing for the image based on the second gain value; and if the first gain value and the second gain value are not similar, carrying out white balance processing for the image based on the first gain value. The white balance processing method of the image solves the technical problems of a relatively poor white balance processing effect caused by easily resulted mismatching of the white balance algorithm selected through a way set by a user and an actual scene.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to an image white balance processing method, device and terminal equipment. Background technique [0002] The human visual system has color constancy, which can obtain the invariant characteristics of the surface color of the object from the changing lighting environment and imaging conditions. For example, humans perceive a white object as white whether viewed indoors under tungsten lighting or in dim light. This is due to the continuous growth of human beings, and the human brain has adapted to the color of objects under different light. [0003] However, the imaging device does not have such an adjustment function, and it is necessary to select an appropriate color balance algorithm to eliminate the influence of the lighting environment on color appearance. There are various white balance algorithms in the prior art, all of which can be used to calculate the ga...
