1.2 Analog-to-Digital Conversion
All CMOS camera sensors incorporates an on-chip analog to digital converter. The bit depth of the output varies
between sensors and can be seen in the table below. Image data is left-aligned across a 2-byte format. The least
significant bits, which are the unused bits, are always zero.
For example, for a 12 bit output, the least significant 4 bits will be zeros in order to fill 2 bytes. E.g. 0xFFF0.
