Abstract

Systems and methods in accordance with embodiments of the invention implement array cameras and array camera modules that have spectral filters disposed outside of constituent image sensors. In one embodiment, an array camera module includes: a lens stack array including lens elements arranged to form a plurality of optical channels, each optical channel including a field-of-view that is shifted with respect to the fields-of-views of each other optical channel so that each shift includes a sub-pixel shifted view of the scene, a glass substrate located within an optical channel, and a spectral filter disposed within, or else proximate to, a glass substrate within the lens stack array; and an imager array including a plurality of focal planes, where each focal plane includes a plurality of rows of pixels that also form a plurality of columns of pixels, and where each focal plane does not include pixels from another focal plane.
