CAMERA MODULES PATTERNED WITH PI FILTER GROUPS
First Claim
1. An array camera module, comprising:
- an M×
N imager array comprising a plurality of focal planes, each focal plane comprising an array of light sensitive pixels;
an M×
N optic array of lens stacks, where each lens stack corresponds to a focal plane, and where each lens stack forms an image of a scene on its corresponding focal plane;
wherein each pairing of a lens stack and its corresponding focal plane thereby defines a camera;
wherein at least one row in the M×
N array of cameras comprises at least one red color camera, at least one green color camera, and at least one blue color camera; and
wherein at least one column in the M×
N array of cameras comprises at least one red color camera, at least one green color camera, and at least one blue color camera.

Abstract
Systems and methods in accordance with embodiments of the invention pattern array camera modules with π filter groups. In one embodiment, an array camera module includes: an M×N imager array including a plurality of focal planes, where each focal plane includes an array of pixels; an M×N optic array of lens stacks, where each lens stack corresponds to a focal plane, and where each lens stack forms an image of a scene on its corresponding focal plane; where each pairing of a lens stack and focal plane thereby defines a camera; where at least one row in the M×N array of cameras includes at least one red camera, one green camera, and one blue camera; and where at least one column in the M×N array of cameras includes at least one red camera, one green camera, and one blue camera.

16. A method of patterning an array camera module with at least one π
- filter group comprising;
evaluating whether an imager array of M×
N focal planes, where each focal plane comprises an array of light sensitive pixels, includes any defective focal planes;assembling an M×
N array camera module using;the imager array of M×
N focal planes;an M×
N optic array of lens stacks, where each lens stack corresponds with a focal plane,wherein the M×
N array camera module is assembled so that;each lens stack and its corresponding focal plane define a camera; color filters are implemented within the array camera module such that the array camera module is patterned with at least one π
filter group comprising;a 3×
3 array of cameras comprising;a reference camera at the center of the 3×
3 array of cameras;two red color cameras located on opposite sides of the 3×
3 array of cameras;two blue color cameras located on opposite sides of the 3×
3 array of cameras; andfour green color cameras surrounding the reference camera; and wherein the array camera module is patterned with the at least one π
filter group such that a camera that includes a defective focal plane is a green color camera.- View Dependent Claims (17, 18, 19, 20)
