Capturing and Processing of Images Captured by Camera Arrays Including Cameras Dedicated to Sampling Luma and Cameras Dedicated to Sampling Chroma

摘要

A camera array, an imaging device and/or a method for capturing image that employ a plurality of imagers fabricated on a substrate is provided. Each imager includes a plurality of pixels. The plurality of imagers include a first imager having a first imaging characteristics and a second imager having a second imaging characteristics. The images generated by the plurality of imagers are processed to obtain an enhanced image compared to images captured by the imagers. Each imager may be associated with an optical element fabricated using a wafer level optics (WLO) technology.

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; anda 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; andfuse images captured by the at least one camera dedicated to sampling luma and the cameras dedicated to sampling chroma to produce an image.
