Patent number: 8405017Abstract: In one aspect, the present invention provides an active pixel sensor array with optimized matching between pixels and strength and frequency of incoming signals such as photons absorbed. The array comprises multiple pixels of individual geometry corresponds to spatial location. Each pixel full-well is adjustable via modifiable pixel conversion gain while maintaining pixel linearity. Furthermore each pixel internally stores multiple of extremely high frequency samples. Variable pixel geometry per row is very advantageous for Echelle spectrograph, where pixel heights are aligned with the spectrograph “order separator” where the resolution changes. In combination with variable geometry, externally adjustable full-well provides for superior spectral line separation in spectroscopy applications. In one embodiment multiple time windows with intermittent resets are stored within each pixel.Type: GrantFiled: December 15, 2010Date of Patent: March 26, 2013Assignee: Imagerlabs Inc.Inventors: Sarit Neter, Eugene Atlas

Patent number: 8334917Abstract: A column buffer for use with a pixel cell array includes an amplifier coupled to three read-out circuits in parallel providing a signal corresponding to accumulated photon-generated charge in a pixel cell plus noise, a reset level plus noise, and a pedestal level, respectively. These three signals are used to generate an ultra-low noise signal Di=Si?Pi-1?G*(Ri?Ri-1), wherein S is the sampled signal, P is the pedestal level, R is the reset level, and G is a gain associated with a pixel cell, and wherein i is a frame number greater than 0. The three signals can be read-out simultaneously. In another embodiment, the three signals are obtained from a column buffer having only one output. In this case, the signals are read-out sequentially.Type: GrantFiled: March 18, 2011Date of Patent: December 18, 2012Assignee: Imagerlabs, Inc.Inventors: Eugene Atlas, Sarit Neter, Kim Loren Johnson

Patent number: 7910874Abstract: A charge coupled device (CCD) includes a low noise charge gain circuit that amplifies charge of a cell dependent upon the charge accumulated by the cell. The low noise charge gain circuit receives clocking signals, such as from an input diode, which allow charge to accumulate in a reservoir well and then flow into a receiving well. The low noise charge gain circuit also receives a voltage signal corresponding to charge accumulated on an associated cell. The amount of charge flowing into the receiving well depends on this voltage signal.Type: GrantFiled: June 9, 2006Date of Patent: March 22, 2011Assignee: Imagerlabs, Inc.Inventors: Gene Atlas, Mark Wadsworth, Richard H.

Patent number: 7623163Abstract: This invention is directed to imaging methods and systems for flexibly addressing and processing imaging pixel sensor elements. A novel architecture is described which allows for a highly integrated, low cost imager with high speed performance and good image quality. The imaging system provides on-the-fly color interpolation, color compensation (also called color correction, color maximization or white balance) and/or fixed pattern noise reduction. The hardware and/or software related to on-the-fly color interpolation, color compensation and/or fixed pattern noise reduction may be provided on-chip.Type: GrantFiled: November 3, 2006Date of Patent: November 24, 2009Assignee: Digital Imaging Systems GmbHInventor: Sarit Neter

Patent number: 7411168Abstract: In one aspect of the present invention, a light sensor is provided in the active pixel sensor cell for sensing incident radiation. The voltage corresponding to the photon-generated or other radiation-generated charge in the active pixel sensor cell is stored on a storage node via a sample-and-hold capacitor. Additional elements, such as source-follower transistors, may reside between the sensing element and the sample-and-hold capacitor. The signal is read via a readout source-follower (RSF) transistor. The readout source-follower drain is connected to the row select switch while its drain is connected to the output node on the column output bus. This configuration couples the storage node to the gate-source capacitance of the readout source-follower transistor. This allows the voltage on the storage node to increase proportionally to the increase in voltage on the readout node when the row select is closed and thus enables the drain current to flow through the RSF to the column output bus.Type: GrantFiled: December 19, 2005Date of Patent: August 12, 2008Assignee: Imagerlaes, Inc.Inventors: Kim Loren Johnson, Eugene Atlas, Sarit Neter

Patent number: 6965395Abstract: The present invention is related to methods and systems for detecting defective imaging array pixels and providing correction, thereby reducing or eliminating visible image artifacts. One embodiment of the present invention provides an on-line bad pixel detection and correction process that compares a first pixel readout value with a first value related to the readout values of other pixels in first pixel's local neighborhood. When the first pixel readout value varies by more than a first amount as compared with the first value, a second value related to the readout values of the neighboring pixels is used in place of the first pixel readout value.Type: GrantFiled: September 12, 2000Date of Patent: November 15, 2005Assignee: Dialog Semiconductor GmbHInventor: Sarit Neter
