Abstract
Embodiments of the present application disclose an image processing method and device, the method comprising: detecting a face region in an image; adjusting an exposure value of the detected face region to be within a preset exposure range interval, wherein the exposure value within the preset exposure range interval does not cause color deviation of the face region; performing white balance calibration on the face region after the exposure value adjustment according to face color imaging standard data to obtain a processed image, wherein the face color imaging standard data is used to represent color imaging states of faces with different skin colors under ideal lighting conditions. The technical solution of the embodiments of the present application can automatically perform white balance calibration on an image based on face color, and can restore the color of a face in an image collected under a complex lighting environment, thereby avoiding the problem of face payment failure.
