Patent ID: 7253393

Claim:
A method for controlling a photosensitive cell, the photosensitive cell comprising a photodiode connected to a read node via a MOS transfer transistor, the read node being connected to a reference voltage via a MOS reset transistor, the photosensitive cell further comprising at least three cyclical phases, including: a waiting phase of non-zero duration, at the end of which the photodiode is isolated from the reference voltage; an integration phase during which the voltage of the photodiode varies from a reset voltage to a useful voltage that depends on the lighting; and a read phase of reading a voltage representative of the useful voltage, wherein the isolation of the photodiode from the reference voltage at the end of the waiting phase comprises an isolation of the photodiode from the read node, the method comprising: setting the MOS transfer transistor to an on state, the MOS reset transistor being in an off state; turning the MOS transfer transistor to an off state; and setting the MOS reset transistor to an on state.
