Synchronous Shutter
In a synchronous (snapshot or global) shutter light integration
takes place on all pixels in parallel, although subsequent readout
is sequential.
sequence for the synchronous shutter. All pixels are light
sensitive at the same period of time. The whole pixel core is reset
Non Destructive Readout (NDR)
The sensor can also be read out in a non destructive way. After
a pixel is initially reset, it can be read multiple times, without
resetting. The initial reset level and all intermediate signals can
be recorded. High light levels saturate the pixels quickly, but a
useful signal is obtained from the early samples. For low light

6. This mode can be activated by setting the NDR SPI register. The NDR SPI register must only be changed during FOT. The NDR bit should be set high during
the first Frame Overhead Time after the pixel array is reset; the NDR bit must be set low during the last Frame Overhead Time before the pixel array is being reset.

simultaneously and after the integration time all pixel values are
sampled together on the storage node inside each pixel. The
pixel core is read out line by line after integration. Note that the
integration and read out cycle can occur in parallel or in
sequential mode.

active pixel array is read multiple times, and reset only once. The
external system intelligence takes care of the interpretation of
