Capturing and processing of images captured by camera arrays incorporating cameras with telephoto and conventional lenses to generate depth maps
First Claim
1. A camera array, comprising:
- a plurality of cameras including at least one camera comprising a telephoto lens and at least one camera comprising a wider field of view lens, where the plurality of cameras are configured to capture a plurality of images comprising different images representing different viewpoints of a same scene, wherein the camera array comprises a one-dimensional array of cameras;
control circuitry for independently controlling imaging parameters and operation of each camera in the plurality of cameras, wherein at least two cameras in the plurality of cameras have similar integration time settings; and
a parallax confirmation and measurement module for detecting and metering parallax using pixel correlation across cameras with similar integration time conditions; and
an image processing pipeline module configured to generate a depth map using the parallax information.

Abstract
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. Lens stack arrays in accordance with many embodiments of the invention include lens elements formed on substrates separated by spacers, where the lens elements, substrates and spacers are configured to form a plurality of optical channels, at least one aperture located within each optical channel, at least one spectral filter located within each optical channel, where each spectral filter is configured to pass a specific spectral band of light, and light blocking materials located within the lens stack array to optically isolate the optical channels.
