Joshua I Pine: Selectable resolution image capture system. ESS Technology, Farjami & Farjami, June 27, 2006: US07068316 (42 worldwide citation)

A selectable resolution image capture system is provided having an array of photocells connected by a circuit that has a full-resolution and at least one low-resolution mode. The circuit converts electrical responses from the photocells, singly, or in grouped combinations, into digital signals. The ...

Lester J Kozlowski, David L Standley: Compact low-noise active pixel sensor with progressive row reset. ESS Technology, Farjami & Farjami, February 24, 2004: US06697111 (34 worldwide citation)

An imaging array of active pixel sensors uses a compact three transistor CMOS implementation for each pixel. A current source at the top of each column creates a distributed feedback amplifier for each pixel in a selected row. The reset amplifier acts as a variable resistance in the source-follower ...

Sophia Wei Chun Kao, Der Ren Chu, Ren Yuh Wang: Method and apparatus for edge enhancement in digital images. ESS Technology, Dorsey & Whitney, August 10, 2004: US06774943 (29 worldwide citation)

An apparatus for edge enhancement of a digital image provided as raw digital image data to an input terminal and for providing processed image data to an output terminal. An offset processing circuit is coupled to the input terminal and configured to receive the raw data and generate offset data. An ...

William E Tennant, Lester Kozlowski, Alfredo Tomasini: Active-passive imager pixel array with small groups of pixels having short common bus lines. ESS Technology, Farjami and Farjami, June 15, 2004: US06750912 (29 worldwide citation)

A shared output visible imager pixel array combines a high optical fill factor with low read noise. A relatively small group of pixels are connected to a relatively short common bus line. An amplifier located in close proximity with the pixels is connected to the common bus line and shared among the ...

Daryl Sartain, Terry Sculley: Variable code frame length for multistream applications. ESS Technology, Fish & Richardson P C, January 2, 2001: US06169747 (26 worldwide citation)

The invention dynamically compensates for differences in data rates for multistreamed systems. Any or all of the streams in a multistreamed system may be individually compensated at one time. In one embodiment, the status of an input buffer is monitored and used to change the number of oversamples w ...
