Capturing and Processing of Images Including Occlusions Captured by Arrays of Luma and Chroma Cameras

摘要

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.

1. A camera array, comprising:
a plurality of imagers, where each imager comprises:
optics comprising at least one lens element and at least one aperture that form an optical channel; andan 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 imagers; and an image processing pipeline module configured to process multiple images captured by the plurality of imagers; wherein the plurality of imagers are configured to capture different images of the same scene and includes at least one imager dedicated to sampling luma and at least one imager dedicated to sampling chroma; wherein the images captured by the plurality of imagers include different occlusions sets, where the occlusion set of a given imager is the portion of a scene visible to a baseline imager in the plurality of imagers that is occluded from the view of the given imager; wherein the plurality of imagers includes a first imager that captures pixels around an edge of a foreground object that is visible to the baseline imager and is in the occlusion set of a second of the plurality of imagers that has the same imaging characteristics as the first imager; and wherein the image processing pipeline module is configured to:
measure parallax using images captured by the plurality of imagers to produce a depth map; andfuse at least the images captured by the baseline imager, and the first and second of the plurality of imagers having the same imaging characteristics to produce an image; and wherein the image processing pipeline module is configured to reconstruct color information around the edge of the foreground object that is visible to the baseline imager and in the occlusion set of the second of the plurality of imagers using the pixels captured by the first imager.
