6.4 Analog to Digital Converter (ADC)
The ASI178 camera records in 10bit ADC and 14bit ADC. You can image at a faster fps rate if you
choose to use 10bit ADC (high speed mode). This camera also supports ROI (region of interest)
shooting, and this smaller ROI has faster fps.
Here is the maximum speed of ASI178 running at 10bit ADC and 14bit ADC.

6.5 Binning
The ASI178 camera supports hardware bin2 and bin4 mode. The ASI178 camera supports
software bin2, bin3 and bin4 mode. Hardware binning is supported by sensor but is done in digital
domain like software binning and use 10bit ADC. The only advantage of hardware binning is
faster fps. We recommend customer to use software binning if you don’t care speed.
