Abstract

The invention discloses an image white balance processing method, device and terminal equipment, wherein the method includes: an image white balance processing method, by extracting color features from the background area in the image, where the color features are used to indicate the background Regional color distribution. Match the applicable conditions of the face white balance algorithm according to the color features, and if the color features match the applicable conditions, perform white balance processing on the image according to the face white balance algorithm used to adjust the face in the image to the skin color. Because the color feature of the image is matched with the applicable conditions of the algorithm, it is judged whether the image is suitable for the face white balance algorithm, which solves the technical problem of poor white balance processing effect caused by artificially setting the algorithm in the prior art.

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] When users are shooting, they often encounter the problem of color cast in the image. For example, an image shot in a room with fluorescent lights will appear greenish, a scene shot indoors under tungsten lighting will have a yellowish cast, and a photo taken in the shade of the sun may appear bluish. [0003] In order to solve this color cast problem, it is necessary to adjust the white balance to restore the color. There are various white balance algorithms in the prior art, all of which can be used to calculate the gain value, and the white balance processing is performed based on the gain value. However, which algorithm is used to calculate the gain value is usually set by the user in the prior art, and the user chooses it. However, such a user setting me...
