Capturing and Processing of Images Including Occlusions Captured by Camera Arrays

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.

主权项

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; wherein the plurality of imagers are configured to capture different images of the same scene; 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; and 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.
