Abstract

The invention discloses an image processing method and device and electronic equipment, and the method comprises the steps: obtaining a digital zoom magnification and a first photographing focal length of a first human face image before digital zoom under the condition that a request for digital zoom of the first human face image is received; determining an equivalent second photographing focal length according to the first photographing focal length and the digital zoom magnification; obtaining a first position coordinate and a second position coordinate of a key point of a face in the firstface image, the first position coordinate being a position coordinate under a first photographing focal length, and the second position coordinate being a position coordinate under a second photographing focal length; and performing face correction on the first face image based on the first and second position coordinates to obtain a second face image. By implementing the method, smooth transformation of portrait perspective effects in different focal length switching processes can be simulated for digital zooming of portraits with different zooming multiplying powers of electronic equipment,a shooting effect similar to zooming of a zoom camera is achieved, the shooting function is enriched, and diversified requirements of users are met.

Description

technical field [0001] The present application belongs to the technical field of image processing, and in particular relates to an image processing method, device and electronic equipment. Background technique [0002] When cameras with different focal lengths shoot portraits, the facial perspective effects of the captured portraits are different, and the visual perception of the fatness and thinness of the face will be different. The telephoto lens will compress the space, and the face will look fat. [0003] At present, the camera on the electronic device is usually a fixed-focus camera. When the user zooms the field of view on the photo preview interface, it is always a digital zoom, that is, the image is simply zoomed in and out for display. Since the optical focal length of the camera has not changed during the digital zooming process, the appearance of the facial contours of the portraits has not changed. It can be seen that the prior art has a single camera function...
