  • Publication number: 20200036951
    Abstract: The present disclosure provides a white balance processing method. The white balance processing method includes the following. Each image of the plurality of successive frame images is processed to determine color temperature corresponding to a main light source. It is determined whether a variation of primary color temperature is greater than or equal to a predetermined threshold. The variation of primary color temperature refers to a difference between the color temperature of the main light source in a second frame image subjected to the color temperature variation and the color temperature of the main light source in a first frame image subjected to the color temperature variation. The white balance process is performed on the second frame image subjected to the color temperature variation according to the color temperature of the main light source in the first frame image subjected to the color temperature variation when the variation of primary color temperature is less than the predetermined threshold.

  • Publication number: 20190130166
    Abstract: The present disclosure relates to a method and apparatus for image processing, and a computer-readable storage medium. The method includes the following actions. Face recognition is performed on an image to be processed to recognize a face region in the image to be processed. Facial feature recognition points in the face region are acquired. Coordinate values of the facial feature recognition points in a coordinate system are acquired. Distances between the facial feature recognition points and angles of a coordinate axis of the coordinate system relative to lines each connecting two of the facial feature recognition points are determined according to the coordinate values. A deviation angle of the face region is determined according to the distances between the facial feature recognition points and the angles of the coordinate axis relative to the lines each connecting two of the facial feature recognition points. A retouching template corresponding to the deviation angle is acquired.
