Capturing and processing of images captured by non-grid camera arrays

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 non-grid camera array, comprising:
a plurality of cameras arranged in a non-grid format and 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 configured to process at least a subset of images captured by the plurality of cameras; wherein the plurality of cameras comprises at least two cameras having different imaging characteristics including different resolutions; wherein the image processing pipeline module comprises a parallax confirmation and measurement module configured to:
measure parallax within the processed images by detecting parallax-induced changes that are consistent across the images taking into account the position of the cameras that captured the images; andgenerate a depth map using the measured parallax.
