Eric R Fossum: Active pixel sensor array with electronic shuttering. California Institute of Technology, Fish & Richardson P C, November 26, 2002: US06486503 (39 worldwide citation)

An active pixel cell includes electronic shuttering capability. The cell can be “shuttered” to prevent additional charge accumulation. One mode transfers the current charge to a storage node that is blocked against accumulation of optical radiation. The charge is sampled from a floating node. Since ...
