AN INTEGRATED ELECTRONIC SHUTTER FOR CHARGE-COUPLED DEVICES

摘要

A charge-coupled device having an array of pixel elements formed in a substrate (22) which device is operable in a first state to expand (25A) the depletion well regions of each pixel element into the substrate for storing incoming photoelectrons therein and in a second state to contract (25B) the expanded depletion well regions to prevent storage of photoelectrons in the contracted depletion well regions.
