Electronic Shutter
An electronic shutter similar to a rolling curtain is implemented on-chip. As shown in
shift register points to the row that is currently being read out. The other shift register points to the row that is currently being reset.
Both pointers are shifted by the same Y-clock and move over the focal plane. The integration time is set by the delay between both
pointers.
In case of a mechanical shutter, the two shift registers can be combined to simultaneously apply the pulses from both sides of the
pixel array. This is to halve the influence of the parasitic RC times of the reset and select lines in the pixel array. This can result in a
reduction of the row blanking time. This is the case when FAST_RESET in the SEQUENCER register is set to 1, or in the
nondestructive readout modes 1 and 2.
