Abstract (en)
[origin: WO2018218354A1] 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.
