The present application discloses an image processing method, device and electronic equipment, including: in the case of receiving a request for digital zooming on a first face image, acquiring the digital zoom ratio and the first face image before digital zooming A photographing focal length; according to the first photographing focal length and the digital zoom ratio, determine an equivalent second photographing focal length; obtain the first position coordinates and the second position coordinates of the key points of the face in the first face image, the first position coordinates is the position coordinates under the first photographing focal length, and the second position coordinates is the position coordinates under the second photographing focal length; based on the first and second position coordinates, the face correction is performed on the first human face image to obtain the second human face image. The implementation of this method can simulate the smooth transformation of the perspective effect of the portrait during the switching process of different focal lengths for the digital zoom of the electronic device with different zoom ratios, and realize the shooting effect similar to the zoom of the zoom camera, which enriches the camera functions and meets the diverse needs of users. .
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...
