Chapter 3 : HOW TO SET A SOFTEDGE SCREEN WITH TWO DEVICES (continued) AXION
PAGE 26
3-2. PROJECTORS CONFIGURATION (continued)
• Softedge curve explanations:
The operation consist of attenuate progressively the light diffused of one projector and in the same time increase
symmetrically the light of the other one. Thus, at any point (X) of the covering area, the sum of light (Y1+Y2) provided
by each projector must be equal to the light that would be provided by one projector alone. The luminance curves of
each projector are represented as follow:
On the touchpanel screen we represent the curve of one projector only: the device automatically calculate the inverted
curve for the other projector of the covering area.
• Softedge curve adjustments:
Display your background source or display the grey scale pattern (horizontal grey scale pattern for horizontal softedge
and vertical grey scale pattern for vertical softedge) available in the Patterns menu.
-Press the Covering touchscreen button, then Enable the Softedge (press on the Disable Softedge check box) to
activate the attenuation. The default value of the softedge curves is thus applied. The covering area may appear brighter
or darker than the other areas of the screen.
-Adjust the Softedge Curve in order to have a uniform image: Move the position of the 2 points of the curve with the
knobs (or press and drag directly the points on the Bezier curve). Then press Send Curve to display the adjustments.
• Then Press Axion’s ENTER button several times to return to the Show menu…
