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

Publication number: 20180070032Abstract: A system and method is provided for performing high dynamic range digital double sampling. More particularly, a CMOS image sensor is provided that includes a pixel array with each pixel sampling both dark and bright values for digital double sampling. After the sampled signals are digitized, a mean dark value is determined and each dark value is further fed to a lookup table that generates an output value taking into account whether the pixel has been saturated. In over exposed conditions, the lookup table will generate a negative value output to eliminate image artifacts. All three values are fed to adder logic circuit that subtracts the mean dark value and the lookup table output from the bright value. This resulting output is fed to a video viewer.Type: ApplicationFiled: August 31, 2017Publication date: March 8, 2018Inventors: Jeroen ROTTE, Rik VISSER, Juul Josephus Johannes VAN DEN HEIJKANT
