| Abstract: Various technologies pertaining to an imaging system with a noncircular
aperture are described herein. An imaging objective with a noncircular
aperture and an anamorphic lens is used to capture a plurality of image
frames of a scene. Each image frame is captured at a different rotational
orientation of the imaging objective with respect to the scene. Each
image frame has a non-uniform spatial resolution. A composite image of
the scene is generated based upon the image frames. The composite image
comprises a first region that has a spatial resolution that is
approximately the same as a spatial resolution of an image generated
using a circular objective with a diameter equal to the largest dimension
of the noncircular aperture, and a second region with a lower spatial
resolution. |
