Abstract

An embodiment of the invention discloses a face-slimming method applied to a series of images captured by an electronic device. The process begins to receive a current image from the series of captured images and detects at least one face landmark corresponding to a face region of the current image. The face landmark of the current image is compared with a reference landmark and a distortion mask is adjusted accordingly. And then, a size of the face region within the current image is then adjusted according to the distortion mask, wherein the distortion mask corresponds to positions of the face landmark.

Description

technical field [0001] The present invention relates to an electronic device and a method thereof for adjusting a face region in an image, in particular to an electronic device and a method thereof for reducing or reducing perspective distortion in a face region according to a distortion mask (perspective distortion). Background technique [0002] Wide-angle cameras are generally widely used to increase the depth of field and reduce the thickness of the lens when the focusing lens is small. Therefore, wide-angle cameras are becoming more and more widely used in mobile phone cameras. However, when shooting a three-dimensional object at close range, the wide-angle camera has the disadvantage of easily causing perspective distortion due to its short focal length. Such a phenomenon usually occurs in video chat applications, because when chatting, the user's face is usually close to the camera, so that the user's face will appear larger (or wider) than when it is photographed a...
