Patent Images
1. A method for automatic convergence of stereoscopic images, the method comprising:
- receiving a stereoscopic image;
selecting a face detected in the stereoscopic image; and
shifting at least one of a left image in the stereoscopic image and a right image in the stereoscopic image horizontally, wherein horizontal disparity between the selected face in the left image and the selected face in the right image before the shifting is reduced.

Abstract
A method for automatic convergence of stereoscopic images is provided that includes receiving a stereoscopic image, selecting a face detected in the stereoscopic image, and shifting at least one of a left image in the stereoscopic image and a right image in the stereoscopic image horizontally, wherein horizontal disparity between the selected face in the left image and the selected face in the right image before the shifting is reduced. In some embodiments, the horizontal disparity is reduced to zero

11. An apparatus comprising:
-
means for performing face detection on a stereoscopic image comprising a left image and a right image; means for selecting a face detected by the face detection; means for determining a first shift amount and a first shift direction for the left image and a second shift amount and a shift second direction for the right image based on horizontal disparity between the selected face in the left image and the selected face in the right image, wherein if the left image is shifted horizontally in the first shift direction by the first shift amount and the right image is shifted horizontally in the second shift direction by the second shift amount, the horizontal disparity is reduced to zero; and means for shifting the left image according to the first shift amount and the first shift direction and the right image according to the second shift amount and the second shift direction. - View Dependent Claims (12, 13, 14, 15)
