Abstract

The application provides a white balance processing method, device and equipment of human face photographing. The method comprises the following steps: detecting environment brightness of a figure photographing scene, and acquiring a first weight factor of a human face white balance algorithm according to the environment brightness, wherein the environment brightness and the first weight factor are in inverse ratio; performing the white balance processing on an original image by applying the human face white balance algorithm and the first weight factor so as to obtain a first computing result; performing white balance processing on the original image by applying the other preset white balance adjusting algorithm so as to acquire a second computing result; acquiring a white balance gain value of the original image according to the first computing result and the second computing result; performing white balance processing on the original image according to the white balance gain value to acquire a corresponding color corrected image. Therefore, the white balance processing is performed by adjusting the weight of the human face white balance algorithm through the environment brightness of the figure photographing scene, the white balance processing effect of the human face photographing is improved, and the user demand is satisfied.

Description

technical field [0001] The present application relates to the technical field of photographing, and in particular to a white balance processing method, device and equipment for face photographing. Background technique [0002] Currently, most shooting devices support white balance processing for face shooting. In related technologies, when taking a portrait in a backlit scene, because the face white balance algorithm will adjust the face in the shade to red and yellow, resulting in the final photo, the background part may be severely reddish and yellowish. Contents of the invention [0003] The present application provides a white balance processing method, device and equipment for face shooting to solve the technical problem in the prior art that when shooting portraits in high-brightness environments such as backlighting, the background is obviously reddish and yellowish. [0004] An embodiment of the present application provides a white balance processing method for fa...
