1. An imaging device comprising: an image sensor having rows and columns of image pixels partitioned into an array of sensor subsections; and an array of wafer lenses disposed over the image sensor, each of the wafer lenses optically positioned to focus image light onto a corresponding sensor subsection in the array of sensor subsections, wherein each sensor subsection includes unlit pixels that do not receive the image light focused from the wafer lenses, each sensor subsection also including lit pixels that do receive the image light focused from the wafer lenses, wherein a rectangular subset of the lit pixels from each sensor subsection are arranged to capture images.
