Patent number: 11049229Abstract: An apparatus for HDR image processing is provided. The apparatus determines an imaging sensitivity value. The apparatus then compares subsets of imaging information with the determined imaging sensitivity value and applies a gamma correction to each subset of imaging information using a gamma low contrast curve or a gamma high contrast curve based on the comparison to obtain the gamma corrected subset of imaging information.Type: GrantFiled: September 26, 2019Date of Patent: June 29, 2021Assignee: GRASS VALLEY CANADAInventors: Jeroen Rotte, Dirk Snoeck-Henkemans, Petrus Gijsbertus Centen

Patent number: 10750109Abstract: A method for performing differential double sampling and a CMOS image sensing device for performing the same. In one example, the CMOS image sensing device includes a pixel array include a multitude of pixels with each pixel formed by a plurality of photodiodes, a floating diffusion point and a plurality of transistors electrically coupled the plurality of photodiodes. Moreover, a column readout circuit with four storage capacitors is selectively coupled to the pixel array by switches so that the storage capacitors can store sampled pixel values. A control circuit connected to the pixel array and the column readout circuit selectively activates the transistors to output to the column readout circuit sampled dark value and bright values of one photodiode and a sampled double bright value of the one photodiode and one additional photodiode.Type: GrantFiled: May 6, 2019Date of Patent: August 18, 2020Assignee: GVBB HOLDINGS S.A.R.L.Inventors: Juul Josephus Johannes Van Den Heijkant, Jeroen Rotte, Petrus Gijsbertus Centen

Patent number: 10531034Abstract: An image sensor that provides global shutter scanning with exposure time control during image capture. The image sensor includes a pixel array with shared pixel units that each include four photodiodes with a floating diffusion node shared therebetween and respective global shutter gates disposed between each photodiode and a supply voltage of the pixel array. Moreover, an image capture timing controller controls an exposure time of each photodiode by adjusting a width of a global shutter reset pulse applied to the plurality of global shutter gates after each readout cycle during image capture to change the respective exposure time of each shared pixel unit.Type: GrantFiled: May 29, 2018Date of Patent: January 7, 2020Assignee: GRASS VALLEY CANADAInventors: Jeroen Rotte, Petrus Gijsbertus Centen, Arnaud Defernez

Publication number: 20190246049Abstract: A camera using a CMOS image sensor based on a shared pixel array technology avails both high definition (HD) and ultra-high definition (UHD) resolution mode formats. Dynamic pixel management allows for both sequential and binned timing formats of pixel signals using switched capacitor noise reduction techniques. When UHD resolution mode is selected, noise can be reduced using both digital double sampling (DDS) or differential digital double sampling (dDDS), and when HD resolution mode is selected noise can be reduced using DDS. Additionally, both rolling shutter and global shutter modes can be selected when HD resolution mode is selected.Type: ApplicationFiled: April 19, 2019Publication date: August 8, 2019Inventors: Petrus Gijsbertus CENTEN, Jeroen ROTTE, Juul Josephus Johannes VAN DEN HEIJKANT, Rudolf VAN REE
