When the averager is on, two frames of data from the ROIC are used to reduce noise.
However if the change in pixel value is more than expected by noise, the averager assumes
this is a change in the scene and uses the value from the more recent frame. This means for
dynamic scenes, the latency is the time between ROIC reads first pixel and CMOS output of
first pixel, or 18ms.
