Lut - IAI AM-200GE User Manual

11.8. LUT

This function can be used to convert the input to the desired output characteristics.
The Look-Up Table (LUT) has 512 points for setup and each point has a 9-bit gain
value. The output level can be created by multiplying the gain data by the input level.
In the AB-200GE, the same LUT characteristic is applied independent of the color
value.
If input data is not in the LUT, the weighted mean average data from upper point and
the lower point are used.
Video output = Video input x LUT value
In order to use LUT control, set:
JAI LUT mode : LUT
LUT Enable : True
AM-200GE / AB-200GE
1
The required characteristics can be achieved by multiplying
LUT parameter and each of 512 points.
