Overview
The IBIS4-1300 is a digital CMOS active pixel image sensor with
SXGA format.
Due to a patented pixel configuration a 60% fill factor and 50%
quantum efficiency are obtained. This is combined with an
on-chip double sampling technique to cancel fixed pattern noise.

... The gain is controlled by a 4-bit word. Gain values vary between 1.2 and 16, and on an exponential scale, as the F-stops of a lens. Of course, increasing the signal amplitude by increasing the gain, will also increase the noise level. The apparent increase of sensitivity is at the cost of a lower dynamic range.
