Abstract

The embodiment of application discloses an image white-balance calibration method, device, storage medium and terminal. The method comprises the following steps: firstly acquiring a preview frame image, judging whether a flare light source is existing in the preview frame image; acquiring a light source direction of the flare light source if the flare light source is existent; and finally, performing the white-balance processing according to the light source direction. The white-balance processing effect under the flare light source can be improved, and the color temperature of the subject canbe more accurately reflected.

Description

technical field [0001] The embodiments of the present application relate to the technical field of mobile terminals, and in particular to an image white balance calibration method, device, storage medium and terminal. Background technique [0002] With the continuous development of mobile terminals, almost every mobile terminal is equipped with a camera function, and can take pictures based on the camera function. The mobile terminal tends to automate the photographing process, and can automatically perform exposure and white balance processing according to the photographing environment. [0003] However, in use, it is found that if the flickering light source is included in the shooting screen, the white balance effect of the captured photo will be poor, and it will not be able to accurately reflect the color temperature of the subject being photographed. Contents of the invention [0004] The purpose of the embodiments of the present application is to provide an image w...
