Problems solved by technology

[0004] In view of this, the embodiment of the present invention expects to provide a method for determining parameters, a terminal and a computer-readable storage medium, which solves the problem of color distortion of a face image in the prior art when performing white balance processing on a picture, and realizes a method based on human The weight of face color information and background color information is used for white balance processing, which reduces the interaction between face color information and background color information in the picture during white balance processing, and improves the quality of the picture

Abstract

The embodiment of the invention discloses a parameter determination method. The method comprises the steps that the first white balance parameter of a first sub-image and the second white balance parameter of a second sub-image are acquired; the proportion value of the first sub-image in an image to be processed is determined so as to obtain a first proportion value; the first weight of the firstwhite balance parameter and the second weight of the second white balance parameter are determined based on the first proportion value; and the target white balance parameter is obtained based on thefirst weight, the first white balance parameter, the second weight and the second white balance parameter. The embodiment of the invention also discloses a terminal and a computer readable storage medium so that white balance processing can be performed based on the respective weight of the face color information and the background color information, and the mutual influence between the face colorinformation and the background color information in the image in case of white balance processing can be reduced.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a method for determining parameters, a terminal and a computer-readable storage medium. Background technique [0002] With the popularization and development of the terminal, the performance of the terminal is getting stronger and stronger, and the functions are becoming more and more abundant. Of course, the camera function of the terminal is becoming more and more powerful. However, with the powerful camera function of terminals and the rapid development of image processing technology, people's requirements for images are also getting higher and higher. After the terminal obtains the image, it usually needs post-optimization on the image to make the image have a better visual effect. In the prior art, an automatic white balance (Automatic White Balance, AWB) technology is usually used to process a portrait picture including a human face. [0003] However, wh...
