1. A camera array, comprising: a plurality of cameras configured to capture images of a scene, where each camera comprises: optics comprising at least one lens element and at least one aperture; and a sensor comprising a two dimensional array of pixels and control circuitry for controlling imaging parameters; a controller configured to control operation parameters of the plurality of cameras; and an image processing pipeline module; wherein the plurality of cameras includes at least one camera dedicated to sampling luma and cameras dedicated to sampling chroma; wherein the cameras that sample chroma are arranged symmetrically within the camera array to address occlusion due to parallax; wherein the image processing pipeline module is configured to: measure parallax using images captured by the plurality of cameras to produce a depth map; and fuse images captured by the at least one camera dedicated to sampling luma and the cameras dedicated to sampling chroma to produce an image; and wherein a camera dedicated to sampling luma forms a central camera and cameras dedicated to sampling chroma are distributed symmetrically around the central camera.
