Region LUT
The Region LUT feature is described in Section 4.6.4. Procedure to set the Region LUT: 1.
Set LUT_EnRegionLUT (in category RegionLUT) to False. This is not mandatory but recommended.
2.
Set LUTEnable (in category LUTControl) to False. This is not mandatory but recommended.
3.
Select LUT 0 by setting LUTSelector (in category LUTControl) to 0.
4.
Set properties LUT_X, LUT_W, LUT_Y and LUT_H (all in category RegionLUT) to desired value.
5.
Set LUT content as described in Section 6.6.4.
6.
If two Region LUT are required, then select LUT 1 by setting LUTSelector (in category LUTControl) to 1 and repeat steps 4 and 5.
7.
Turn on LUT by setting LUTEnable to True.
8.
Turn on Region LUT by setting LUT_EnRegionLUT (in category RegionLUT) to False.
6.6.4
User defined LUT settings
This section describes how to set user defined LUT values. It is assumed that the LUT was selected as described in Section 6.6.2 or Section 6.6.3. For every LUT value the following steps must be done: 1.
Set LUTIndex (in category LUTControl) to desired value. The LUTIndex corresponds to the grey value of the 12 bit input signal of the LUT.
2.
Set LUTValue (in category LUTControl) to desired value. The LUTValue corresponds to the grey value of the 8 bit output signal of the LUT. The LUTIndex is auto incremented internally after setting a LUTValue. If consecutive LUTIndex are written, then it is required to set LUTIndex only for the first value. For the next values it is sufficient to set only the LUTValue.
6.6.5
Predefined LUT settings
Some predefined LUT are stored in the camera. To activate a predefined LUT: 1.
Select LUT and RegionLUT (if required) as described in Section 6.6.2 and Section 6.6.3.
2.
Set LUTAutoMode (in category LUTControl) to the desired value. The available settings are described in property list of the camera which is contained in the PFInstaller.
3.
If the LUTAutoMode requires additional settings (e.g. Gamma LUTAutoMode), then it can be set with LUTAutoValue.
