Projector Setup and System Adjustments
Accurate projector setup is essential for creating seamless images. The projectors must be precisely aligned to
overlap the adjacent blending regions. The brightness, contrast and color balance of the projectors must be adjusted
to provide a uniform appearance across the entire screen. Custom test patterns and an alignment procedure are
used to simplify this process and provide an optimal result. It should be noted that mixing and matching projectors is
not recommended as it makes the adjustment process much more difficult.
Typical System Configuration
The system configuration for a typical wide-screen display application is shown in Figure 1.5. The system includes a
ScreenPRO PLUS Seamless Switching and Control System as well as the BlendPRO Wide-Screen Image
Processor. The ScreenPRO PLUS console provides fully integrated control for setup, adjustment and real time
control of all image-processing features. Image source material may be derived from a single HD source or from a
multi-head graphics engine. Video sources are routed via the internal router to the Video Processing boards within
the ScreenPRO PLUS. The ScreenPRO PLUS provides seamless switching capabilities and may be used to
superimpose PIP source material onto the wide screen image. The PIP windows may be located at any position of
the display even across the blend regions. The BlendPRO unit provides programmable image overlap and edge-
feathering functions to support a fully seamless wide screen display. A screen shot of a typical edge blended
application is provided in Figure 1.6.
