GAIN ADJUSTABLE SENSOR PIXELS, ARRAYS AND ARRAY SYSTEMS AND METHODS THEREFOR

摘要

A sensor pixel 100 including a sensor 3, charge storage 5, a reset block 7 having a reset input 11, readout block 9, and a charge leakage gain adjustment block 17 having a gain adjustment control input 19. The sensor 3, charge storage 5, reset block 7, readout block 9, and charge leakage gain adjustment block 17 are each operatively connected to a node A. Adjusting the gain of a sensor pixel 100 by storing charge from a sensor 3 in a charge storage 5 connected to a node A, leaking charge from the charge storage 5 to reduce the charge at node A, and reading out a state of the pixel represented by the charge of node A.
