Table 131: Advanced register: LUT
Note
The BitsPerValue field indicates how many bits are read from
the LUT for any gray-value read from the sensor. To determine
the number of bytes occupied for each gray-value round-up
the BitsPerValue field to the next byte boundary.
Examples:
•
BitsPerValue = 8
1 byte per gray-value
•
BitsPerValue = 14
2 byte per gray-value
Divide MaxLutSize by the number of bytes per gray-value in
order to get the number of LUT entries (gray levels): that is 2
n
with n=number of bits read from sensor.
