Abstract:
An image sensor and a method for acquiring images by sampling of the level of a voltage representative of the charge of a photodiode, in which a first sample is taken during a reset of the charge level of the photodiode; and a second sample is taken provided that the decrease slope of the voltage after the reset is lower than a threshold, said second sample replacing the first one.
