Claim:
1. A computer-implemented method of lens shift correction for a camera array comprising: obtaining image data of multiple cameras wherein at least one of the cameras is to perform autofocus; determining shift parameters to shift the position of misplaced points of individual images of the autofocus camera and to correct positions determined by using corresponding points on images of non-autofocus cameras of the multiple cameras; warping the images from the autofocus camera by using the parameters to modify the positions of the misplaced points on the images of the autofocus camera; and establishing at least two epipolar lines each extending from a corresponding point of a misplaced point and from an image of a non-autofocus camera, and extending to the image of the autofocus camera, wherein the intersection of the epipolar lines on the image of the autofocus camera is the correct position of the misplaced point.
