US Patent:

7808528, Oct 5, 2010

Filed:

Jul 21, 2008

Appl. No.:

12/177048

Inventors:

Mark Alan Massie - Santa Ynez CA, US
Jon Paul Curzan - Arroyo Grande CA, US
Christopher Robert Baxter - Santa Barbara CA, US
Ralph Roch Etienne-Cummings - Washington DC, US

Assignee:

Nova Research, Inc. - Solvang CA

International Classification:

H04N 5/228

US Classification:

34820814

Abstract:

A variable acuity imager incorporates an array of detection elements for light energy, in the visible, infrared, ultraviolet, or light energy in another region of the electromagnetic spectrum with a means to change the spatial configuration of the array to include “superpixels” by combining energy detected by adjacent elements, thus permitting any number of high-resolution “foveal” regions to be placed within the confines of the focal plane array and moved around at the frame rate of the imaging device. Detectors to measure the pitch, yaw and roll angle rates of background imagery using velocity-sensing circuitry are employed for variation of the foveal regions to accommodate motion of the array.
