1. A method for combining frames of video from a plurality of cameras arranged in a camera array, comprising the steps of:
- obtaining a first frame from a first camera, and a second frame from a second camera, wherein at least a portion of said first frame and said second frame include a common field of view;
stretching at least a portion of said first frame to reduce an image disparity between said common field of view of said first frame and said second frame; and
, combining said common field of view of said first frame and said second frame subsequent to said step of stretching.

Abstract
A camera array captures plural component images which are combined into a single scene. In one embodiment, each camera of the array is a fixed digital camera. The images from each camera are warped to a common coordinate system and the disparity between overlapping images is reduced using disparity estimation techniques.

9. A method for combining a plurality of images captured from a plurality of cameras of a camera array into a panoramic image, comprising the steps of:
-
adjusting a first portion of a first image to reduce image disparity between said first portion of said first image and a second image;
adjusting a second portion of said first image to reduce image disparity between said second portion of said first image and a third image; and
,combining said first image, said second image, and said third image into a panoramic image. - View Dependent Claims (10, 11, 12, 13)

14. An apparatus for producing a panoramic video, comprising:
-
a camera array including a plurality of cameras;
an image obtaining device, wherein said image obtaining device obtains a first image from a first camera in said camera array and a second image from a second camera in said camera array, wherein said first image and said second image include a common field of view;
an image adjustor, wherein said first image adjustor adjusts at least a portion of said first image by stretching said first image a first distance to reduce an image disparity between said common field of view of said first image and said second image; and
,an image combiner, wherein said image combiner combines at least a portion of said first image and at least a portion of said second image.
