Patent number: 11910109Abstract: In one implementation, an event sensor includes a plurality of pixels, an external readout line shared among the plurality of pixels, and an external processing circuit. Each pixel is configured to output pixel data indicative of an intensity of incident illumination. The external processing circuit is configured to output a stream of pixel events. Each respective pixel event is generated when a comparator of the external processing circuit obtains a sample of pixel data from a particular pixel via the external readout line that breaches a threshold value.Type: GrantFiled: July 15, 2021Date of Patent: February 20, 2024Assignee: Apple Inc.Inventors: Nikolai E. Bock, Emanuele Mandelli, Dario Clocchiatti

Publication number: 20230044950Abstract: A pulse-width modulation (PWM) image sensor is described herein. The PWM image sensor may have a stacked configuration. A top wafer of the PWM image sensor may have a charge-to-time converter and a logic wafer, stacked with the top wafer, may include a time-to-digital converter. The PWM image sensor may utilize variable transfer functions to avoid highlight compression and may utilize non-linear time quantization. A threshold voltage, as input to a charge-to-time converter, may additionally be controlled to affect light detection, dynamic range, and other features associated with the PWM image sensor.Type: ApplicationFiled: July 14, 2022Publication date: February 9, 2023Inventors: Nikolai E. Bock, Andrew Kenneth John McMahon, Dario Clocchiatti, Emanuele Mandelli, Gennady A. Manokhin, Robert H. Mullis

Patent number: 10757351Abstract: In various embodiments, image sensors and methods of operating the image sensors are disclosed. In an example embodiment, a pixel circuit having a first electrode is coupled to a reset transistor and to a first region of an optically sensitive layer, and a second electrode is coupled to a pixel sense node and to a second region of an optically sensitive layer. The electrical path from the first electrode, through the optically sensitive layer, and into the second electrode functions as a variable resistor. Other devices and methods of operating the devices are disclosed.Type: GrantFiled: September 23, 2018Date of Patent: August 25, 2020Assignee: INVISAGE INC.Inventors: Emanuele Mandelli, Ralph Beaudouin, Aurelien Philippe Bouvier, Dario Clocchiatti, Lionel Barrymore Joseph Barrow, Zachary Michael Beiley

Patent number: 10681296Abstract: In various embodiments, methods and related apparatuses for sealing down pixel sizes in quantum film-based image sensors are disclosed. In one embodiment, an image sensor circuit is disclosed that includes circuit includes an optically sensitive layer, a first pixel having a first electrode coupled to a first region of optically sensitive layer, a second pixel having a second electrode coupled to a second region of optically sensitive layer, and a readout circuit having at least one transistor that is shared among the first pixel and the second pixel. In a first time interval, the transistor is used in a readout of a signal related to illumination of the first pixel over an integration period. During a second time interval, the transistor is used in a readout of a signal related to illumination of the second pixel over an integration pixel. The signals thusly read constitute a time-domain multiplexed (TDM) signal.Type: GrantFiled: May 24, 2018Date of Patent: June 9, 2020Assignee: INVISAGE TECHNOLOGIES, INC.Inventors: Emanuele Mandelli, Dario Clocchiatti, Aurelien Philippe Bouvier
