Abstract:
An imaging device having pixels that store charge from a photosensor under at least one storage gate during a sampling period. A driver used to operate the at least one storage gate, estimates how much charge in the pixel exceeds a predetermined limit during a non-destructive pixel sensing operation. A specific voltage is stored on the pixel's floating diffusion region to flag how many times the pixel exceeded the limit. The final pixel signal and the stored information is readout at the end of integration period to create a sum that represents the pixel's final signal value.
