Correcting Color Convergence Using Ecc - Christie CineLife+ CP4415-RGB User Manual

Correcting color convergence using ECC

Use Electronic Color Convergence (ECC) to correct the color convergence across the screen by
correcting four discrete points at the corners of the screen.
Perform ECC only when you are satisfied with the position of the image on the screen.
1. In the left navigation menu, select Image Settings > ILS File Setup.
2. Use the arrow to select an ILS file to store the ECC settings.
3. On the ILS File Setup page, select ECC.
Each corner of the screen displays three separate sprites, one for each primary color. The user
interface displays the Test Pattern controls.
4. Set the Screen Type to Flat or Scope.
This sets the test pattern and the location of the sprites on the screen. Each sprite appears as
the letter L.
5. Set the Sprite Color to Move and Show.
When first opening the ECC, all Show and all Move colors are selected, so all three sprites are
displayed and all three sprites are moved by the directional pad.
6. Select a Step Size to control the granularity of the steps from coarse (1/8 pixel per step) to
fine (1/64 pixel per step) when using the directional pad.
Sprites can be moved a maximum of 20 pixels.
7. Choose a corner by selecting the circle at a corner of the dashed rectangle.
The selected corner is indicated by a green circle. The X/Y pixel offset (from no correction)
displays in red, green, and blue text corresponding to each sprite.
8. Use the directional pad to move the sprites towards the center of the screen.
9. Adjust each sprite so they overlap to create a single white sprite.
In the example below, the red sprite was moved down and the blue sprite was moved to the
right.
10. To set the convergence for that corner of the screen, select Apply.
