Output LookUp Table. 8.13
Introduction 8.13.1.
The camera has an Output LookUp Table. This table can be used to correct each pixel by a user
specified value. It can be useful if, for instance, Gamma correction is desired.
In order to load the look-up table values, the camera should be prepared to receive the values.
This is done through the OLUTBGN command.
Command syntax: OLUTBGN
NOTE: When an OLUTBGN command is received if the LUT is already opened and/or the LUT is
already (partly) filled, error 120 is issued and the LUT-status is reset.
Output LookUp Table content 8.13.2.
The user look up table is loaded by command OLUT. Entries can be retrieved by OLUT?
Command syntax: OLUTx
Where 0
≤
x
≤
4095
To fill the OLUT, it should first be opened through the OLUTBGN command.
The Output LookUp Table is based on the 12 bit output resolution. Therefore a total of 4096 values
have to be entered, beginning with the entry replacing the input value 0 up to the input value 4095.
The LUT pointer is incremented at each LUT entry.
NOTE 1: If there is no preceeding OLUTBGN command there will be no action and error result is set to
121.
NOTE 2: If the number of OLUT commands exceeds the LUT size (4096) there will be no action and
error result is set to 123.
Down scaling the output resolution to 8 or 10 bit is done after the LUT.
