Digitization bit depth
In case of most cameras changing the sensor digitization bit depth may increases the maximum possible frame rate,
but does not affect the saturation level.

Cameras featuring 2
nd
generation of Sony IMX sensors (MX031, MX050, MX089, MX124) have special 8bit digitization mode,
which features same conversion gain as 10bit mode using only ¼ of the saturation. This lead to four times brighter images
compared to 10bit and 12bit modes.
