1. An array camera configuration, comprising:
- at least two constituent array cameras, where each constituent array camera comprises;
a plurality of cameras, where each camera comprises optics that form an image on a focal plane defined by an array of pixels that capture image data and have fields of view that form a combined field of view for the constituent array camera;
wherein each of the at least two constituent array cameras differ with respect to at least one of combined field of view and viewing direction;
a processor;
memory containing an image processing application and calibrated warp data;
wherein the image processing application directs the processor to;
for each of the at least two constituent array cameras;
obtain image data from the cameras in the constituent array camera;
generate a depth map using the image data captured by the cameras in the constituent array camera; and
synthesize an image using the image data captured by the cameras in the constituent array camera and the depth map;
construct an enhanced image using the image data obtained from the cameras in the at least two constituent array cameras by;
warping at least a first of the synthesized images into a viewpoint of a second of the synthesized images using a depth map for the first of the synthesized images and calibrated warp data; and
blending the at least a first of the synthesized images warped into the viewpoint of the second of the synthesized images and the second of the synthesized images to create the enhanced image.

Abstract
Systems and methods for implementing array camera configurations that include a plurality of constituent array cameras, where each constituent array camera provides a distinct field of view and/or a distinct viewing direction, are described. In several embodiments, image data captured by the constituent array cameras is used to synthesize multiple images that are subsequently blended. In a number of embodiments, the blended images include a foveated region. In certain embodiments, the blended images possess a wider field of view than the fields of view of the multiple images.

20. An array camera configuration, comprising:
-
at least two constituent array cameras, comprising; a first constituent array camera comprising a plurality of cameras, where each camera comprises;
optics that form an image on a focal plane defined by an array of pixels that capture image data; and
have fields of view that form a first combined field of view in a first viewing direction;a second constituent array camera comprising a plurality of cameras, where each camera comprises;
optics that form an image on a focal plane defined by an array of pixels that capture image data; and
have fields of view that form a second combined field of view in a second viewing direction;wherein the plurality of cameras in the first constituent array camera have fields of view that are narrower than and within the fields of view of the plurality of cameras in the second constituent array camera; wherein the plurality of cameras in the first constituent array camera capture image data at a higher angular resolution than the image data captured by the plurality of cameras in the second constituent array camera; a processor; memory containing an image processing application and calibrated warp data; wherein the image processing application directs the processor to; obtain image data from the cameras in the first and second constituent array cameras; generate separate depth maps using the image data captured by each of the first and second constituent array cameras; and synthesize separate high resolution images by performing a super-resolution process using the image data captured by each of the first and second constituent array cameras and the depth maps generated using the image data captured by each of the first and second constituent array cameras; and construct an enhanced image using the two synthesized images and the depth maps used to synthesize images by; warping a first of the synthesized images into a viewpoint of a second of the synthesized images using the depth map used to synthesize the first of the synthesized images and calibrated warp data; and blending the first of the synthesized images warped into the viewpoint of the second of the synthesized images and the second of the synthesized images to create the enhanced image; wherein the enhanced image has a field of view of the image synthesized using the image data captured by the second constituent array camera and includes a foveated high resolution region with an angular resolution of the image synthesized from the image data captured by the first constituent array camera.
