Pixel bit depth
The sensor has a configurable 8, 10 or 12 bits integrated Analog/Digital converter.
The 10 bits conversion is not supported by the camera.
The pixel format is selected using the standard
SFNC PixelFormat
register.

Name Access Values Description
PixelFormat
RW Mono8, Mono12 Monochrome 8-bit or monochrome 12-bit unpacked
The choice of pixel bit depth influences the maximum achievable framerate.

8 bits 8-bits unsigned integers xxx fps
12 bits 12-bits unsigned integers xxx fps
Note: Modification of the pixel format reverts many registers to their default value.
Analog control
Conversion efficiency
There are two built-in conversion gain: High Conversion Gain (HCG) and Low Conversion Gain (LCG).
HCG must be used for low light conditions. For bright light conditions and high illuminated scenes, LGC
must be used.

ConversionEfficiency
RW Low The selected conversion efficiency is low.
High The selected conversion efficiency is high.
Analog and digital gains
The sensor has an additional gain up to 48dB gain in LCG and HCG modes:

0 dB to 24 dB : Analog Gain (0.1 dB step)

24.1 dB to 48 dB : Digital Gain (0.1 dB step)
Analog gain has the advantage to reduce noise. When digital gain is applied, pixels values are multiplied
without any effect on noise value.
