Stereo Scan 440 - DCU

Overview
The input LUT is used to perform a translation on the input signal as defined by
the pattern loaded into the LUT.
The pattern may be ttansparent (no ttansfonnation). a gamma ttansfonnation or
a user defmed pattern created in the Input LUT Window.
The LUT pattern is represented by a set of lines connecting points. Each point
has as its co-ordinates the input grey level (X in the range 0.255) and the output
grey level (Y in the range 0.255). The minimum definition is two points at X=O
and X=255. Other points may be added at other X values, only one point may
reside at a specific X value.
The points list may be manipulated using the add, move and delete functions. In
addition patterns of points may be created using the steps or sawtooth functions.
The list of points may be saved or loaded from file. The width of the window
may be changed using the scale function.
Reset
This resets the points list to a transparent function (2 points 0,0 and 255,255).
