Abstract
An imaging array and method for using the same that are adapted for backside illuminated imaging arrays utilizing a global shutter are disclosed. The imaging array includes a plurality of pixel sensors having an ordered array of pixel sensors. Each pixel sensor includes a main photodiode and a correction photodiode. A controller resets all of the main photodiodes at a first time that is the same for all of the pixel sensors, resets all of the correction photodiodes at a second time that is the same for all of the pixel sensors after the first time, and sequentially reads out the pixel sensors. The pixel sensor is read out at a third time that is different for different ones of the pixel sensors. A correction charge is measured that corrects for the different readout times.
