Method for adjusting video frame

Abstract

A method for adjusting a face area of a user in the video frame captured by a camera lens is disclosed. In the method, an edge of an image in the video frame is detected, wherein the image contains a face area representing a face of a user. Then, a plurality of facial features of the face are extracted from the face area according to the image edge. Then, a facial feature database is referred to for the facial features to estimate a tilt angle between a plane corresponding to the face of the user and a focusing direction of the camera lens towards the face on capturing the video frame. Finally, the estimated tilt angle is used for adjusting relative proportion between image parts in the face area. As a result, the video frame displaying an image effect of the face as seen by a person from a position in front of and level with the face and having no tilted image of the face is obtained.
