1. System Design of Edge Blending and Cautions

In order to steadily project a large image or high-definition image using multiple units of

projector without showing an image boundary such as a joint line or change in brightness

and hue, attention should be paid to several points in the selection of projectors, screen and

delivery equipment as well as the method of installation.

(1) Selection of a screen and lens based on the difference between front and rear

projection systems

1) Front projection system

The most suitable system for edge blending.

Select a zoom lens other than a short-focus fixed lens (ET-D75LE5).

* Points to keep in mind

A short-focus fixed lens does not permit zooming or lens shift and the projector needs to

be placed at the center of each image. The lens causes slight distortion of the projected

image around the lens perimeter and does not permit accurate image overlapping at the

joint part.

The screen should be selected from white mattes (screen gain 1.0 or less) with a wide view

angle

* Points to keep in mind

Glass-beaded, pearl-surface or silver-surface screens have high screen gain and a

narrow view angle. When a projected image is viewed from an oblique angle, a difference

in brightness is visible at the joint line.
