Function of
Lookup Tables
Lookup tables (LUT) are used to map signal levels to the required level, range and
input characteristics of different downstream products and applications.
They are basically tables containing code values. These do not necessarily de-
scribe a simple mathematical function, but are rather results of subjective tests
and research.
Therefore, it is very important to understand how these lookup tables work in order
to preserve the required image information.
Lookup tables can be applied at the output and / or input of many products and
software applications.
It is essential to take the time and effort to analyze and test the entire chain to find
out the best lookup table combinations and setups for each application.
User defined
LUT
This menu allows to use customer specific lookup-tables. To generate and per-
form a download of lookup-tables to a data output board see the detailed descrip-
tion of the separate SDCMAINT manual provided in the supplements of the “Spirit
DataCine Customer’s Manual”.
