Patent number: 11284034Abstract: Signals representative of total photocharge integrated within respective image-sensor pixels are read out of the pixels after a first exposure interval that constitutes a first fraction of a frame interval. Signals in excess of a threshold level are read out of the pixels after an ensuing second exposure interval that constitutes a second fraction of the frame interval, leaving residual photocharge within the pixels. After a third exposure interval that constitutes a third fraction of the frame interval, signals representative of a combination of at least the residual photocharge and photocharge integrated within the pixels during the third exposure interval are read out of the pixels.Type: GrantFiled: April 27, 2020Date of Patent: March 22, 2022Assignee: Rambus Inc.Inventors: Jay Endsley, Thomas Vogelsang, Craig M.

Patent number: 11012649Abstract: A control pulse is generated a first control signal line coupled to a transfer gate of a pixel to enable photocharge accumulated within a photosensitive element of the pixel to be transferred to a floating diffusion node, the first control signal line having a capacitive coupling to the floating diffusion node. A feedthrough compensation pulse is generated on a second signal line of the pixel array that also has a capacitive coupling to the floating diffusion node. The feedthrough compensation pulse is generated with a pulse polarity opposite the pulse polarity of the control pulse and is timed to coincide with the control pulse such that capacitive feedthrough of the control pulse to the floating diffusion node is reduced.Type: GrantFiled: July 3, 2019Date of Patent: May 18, 2021Assignee: Rambus Inc.Inventors: Michael Guidash, Jay Endsley, John Ladd, Thomas Vogelsang, Craig M.

Patent number: 10798322Abstract: A pixel array within an integrated-circuit image sensor is exposed to light representative of a scene during a first frame interval and then oversampled a first number of times within the first frame interval to generate a corresponding first number of frames of image data from which a first output image may be constructed. One or more of the first number of frames of image data are evaluated to determine whether a range of luminances in the scene warrants adjustment of an oversampling factor from the first number to a second number, if so, the oversampling factor is adjusted such that the pixel array is oversampled the second number of times within a second frame interval to generate a corresponding second number of frames of image data from which a second output image may be constructed.Type: GrantFiled: September 25, 2018Date of Patent: October 6, 2020Assignee: Rambus Inc.Inventors: Craig M.

Patent number: 10356350Abstract: Photocharge is accumulated within an image sensor pixel array during a first exposure interval. At conclusion of the first exposure interval, accumulated photocharge is discarded from a first subset of the pixels to emulate absence of incident light with respect to those pixels. After discarding accumulated photocharge from the first subset of the pixels, first and second readout signals are generated, the first readout signals corresponding to respective pixels not included in the first subset and indicative of photocharge accumulated therein, and the second readout signals corresponding to respective pixels included in the first subset.Type: GrantFiled: July 31, 2018Date of Patent: July 16, 2019Assignee: Rambus Inc.Inventors: Michael Guidash, Jay Endsley, John Ladd, Thomas Vogelsang, Craig M.

Patent number: 10178329Abstract: In an integrated-circuit image sensor having a pixel array, a first subframe readout policy is selected from among a plurality of subframe readout policies, each of the subframe readout policies specifying a first number of subframes of image data to be readout from the pixel array for each output image frame and respective exposure durations for each of the first number of subframes of image data, wherein a shortest one of the exposure durations is uniform for each of the subframe readout policies. Each of the first number of subframes of image data is read out from the pixel array following the respective exposure durations thereof while applying a respective analog readout gain. The analog readout gain applied during readout of at least a first subframe of the first number of subframes is scaled according to a ratio of the shortest one of the exposure durations to the exposure duration of the first subframe.Type: GrantFiled: May 21, 2015Date of Patent: January 8, 2019Assignee: Rambus Inc.Inventors: Thomas Vogelsang, Craig M.
