Patent number: 11622087Abstract: An imaging system includes a pixel array configured to generate image charge voltage signals in response to incident light received from an external scene. An infrared illumination source is deactivated during the capture of a first image of the external scene and activated during the capture of a second image of the external scene. An array of sample and hold circuits is coupled to the pixel array. Each sample and hold circuit is coupled to a respective pixel of the pixel array and includes first and second capacitors to store first and second image charge voltage signals of the captured first and second images, respectively. A column voltage domain differential amplifier is coupled to the first and second capacitors to determine a difference between the first and second image charge voltage signals to identify an object in a foreground of the external scene.Type: GrantFiled: February 4, 2021Date of Patent: April 4, 2023Assignee: OmniVision Technologies, Inc.Inventors: Zhiyong Zhan, Tongtong Yu, Zheng Yang, Wei Deng

Patent number: RE45282Abstract: An image sensor system using offset analog to digital converters. The analog to digital converters require a plurality of clock cycles to carry out the actual conversion. These conversions are offset in time from one another, so that at each clock cycle, new data is available. A system includes a CMOS active pixel image sensor having an array for photoreceptors to convert an image into an analog signal. The CMOS image sensor converts the analog signal into a digital signal using a pipelined analog to digital converter.Type: GrantFiled: January 24, 2012Date of Patent: December 9, 2014Assignee: Round Rock Research, LLCInventors: Eric R.
