Definition
Diese Klassifikationsstelle umfasst:- Circuits for control of blooming by resetting pixels that are not readout but are adjacent to pixels that are readout so as to prevent saturation of non-read pixels from effecting adjacent readout pixels;
- Circuits for sweeping out electric charges beforehand so as not to leak while one prior row is being exposed;
- Circuits for controlling pixels comprising a storage element for storing the overflow photo-charges, the stored overflow charge is used to extend the dynamic range of the image sensor;
- Evacuation of excess charges produced by the exposure via the output lines or the reset lines of addressed sensors.
- Active CMOS pixels sensors comprising a dedicated reset or overflow transistor directly connected to the photoelectric converter, such a pixel is known as 5T pixel.
