Capturing and processing of images using camera array incorperating Bayer cameras having different fields of view
First Claim
1. A camera array, comprising:
- a plurality of Bayer cameras capturing a plurality of images and forming at least three rows of cameras and at least three columns of cameras, where each camera includes separate optics and a plurality of sensor elements, and each camera is configured to independently capture an image of a scene;
wherein the optics of each camera are configured so that each camera has a field of view of the scene that is shifted with respect to the field-of-views of the other cameras;
wherein the plurality of images captured by the plurality of Bayer cameras include different occlusion sets, the occlusion set of a specific image captured by a given camera is the portion of a scene visible to a baseline camera from the plurality of cameras that is occluded from the view of the given camera; and
wherein the plurality of cameras includes a first camera that captures pixels around an edge of a foreground object that is visible to the baseline camera and is in the occlusion set of a second of the plurality of cameras.

Abstract
Systems and methods for implementing array cameras configured to perform super-resolution processing to generate higher resolution super-resolved images using a plurality of captured images and lens stack arrays that can be utilized in array cameras are disclosed. An imaging device in accordance with one embodiment of the invention includes at least one imager array, and each imager in the array comprises a plurality of light sensing elements and a lens stack including at least one lens surface, where the lens stack is configured to form an image on the light sensing elements, control circuitry configured to capture images formed on the light sensing elements of each of the imagers, and a super-resolution processing module configured to generate at least one higher resolution super-resolved image using a plurality of the captured images.

20. A method for synthesizing a higher resolution image from a plurality of images captured from different viewpoints, comprising:
capturing a plurality of images, where; the plurality of images are captured using a plurality of Bayer cameras that form at least three rows of cameras and at least three columns of cameras; the plurality of images include different occlusion sets, wherein the occlusion set of a specific image captured by a given camera is the portion of a scene that is visible to a baseline camera from the plurality of cameras that is occluded from the view of the given camera; and the plurality of images includes a first image that captures pixels around an edge of a foreground object that is visible to the baseline camera and is in the occlusion set of a second image captured by a second of the plurality of cameras. - View Dependent Claims (21)
