Conventional image sensors have improved with technology scaling mainly by reducing pixel size to increase spatial resolution [1,2]. As resolution approaches the limits of existing optics, is there much to gain from further pixel scaling? In , we argue that further scaling can provide new imaging capabilities via a multi-aperture (MA) architecture, which… (More)
— An image sensor comprising an array of apertures each with its own local integrated optics and pixel array is presented. A lens focuses the image above the sensor creating overlapping fields of view between apertures. Multiple perspectives of the image in the focal plane facilitate the synthesis of a 3D image at a higher spatial resolution than the… (More)
— A prototype of a new high dynamic range readout scheme targeted for 3D-IC IR focal plane arrays is described. Dynamic range is extended using synchronous self-reset while high SNR is maintained using few non-uniformly spaced captures and least-squares fit to estimate pixel photocurrent. The prototype comprises of a 16×5 readout pixel array fabricated in a… (More)
A complete in-stream lossless hardware image compression engine is implemented with a channel splitting and division-free arithmetic encoding technique. The hardware is less than 7000 gates and requires 0.3 mm 2 of area in a 0.35 µm process. An average of 46% compression is achieved over a diverse set of images.
