Basler sprint Mono Cameras 141
6.6 Lookup Table
The sensor circuitry in the camera acquires pixel data at 12 bit depth. However, when the camera
is set for an 8 bit video data output format, pixel data is only output at 8 bit depth. With the camera
set for an 8 bit format, it normally converts the 12 bit data output from the sensor to 8 bit data by
simply truncating the least significant 4 bits.
The lookup table feature lets you create a customized table that can be used to map the 12 bit
values output from the sensor to 8 bit values that will be transmitted from the camera. Once you
have entered values into the lookup table, you can use the table to control 12 bit to 8 bit conversion
rather than relying on simple truncation.
The lookup table has 1025 indexed locations with an 8 bit value stored at each index like this:
Note
When the camera is operating in an 10 bit or 12 bit output mode and when the
lookup table feature is enabled, only the 8 MSBs of the transmitted data will
carry information. The 2 or 4 LSBs, respectively, will be packed with zeros.
