GeoBox Applications

Geometry Adjustment Image Stacking

Active/Passive 3DEdge Blending

∗ Use low cost projector

∗ No lens shift required

∗ No PC, more reliable

∗ Easy, low entry barrier

∗ Quick setup

∗ Low cost for after service

GeoBox Advantage for system integrators

Edge Blending(Become seamless big screen

using multiple projectors)

10

∗ Enlarge the display at lower cost

EB will have more than 50% cost saving

∗ Increase image resolution, up to 10,000 pixels

∗ Change aspect ratio

Two XGA = 2.35: 1 (movie standard)

∗ Shorten projection distance

60% distance to get the same width (2x Projectors)

∗ Immersive feeling

360 degree, “M” shape screen, Dome

11

Why need Edge Blending

∗ No PC required, more reliable for long term use

∗ More flexible in input source connection

∗ High performance video without PC lag issue

∗ Reserve PC CPU power for interactive and other applications

∗ Low entry barrier for system integrators

∗ Save cost in installation and after service

12

Edge Blending--HW vs. SW(Advantage in hardware solution)

∗ Basic functions required: A+B+C∗ A. Warp: Geometry alignment

∗ B. Video wall setting: ∗ Image split (Zoom)

∗ Location assignment (Pan)

∗ Overlap pixel alignment (Overlap)

∗ C. Edge blend∗ Select edge

∗ Set overlap pixels

Active 3D

25

∗ Multiple projectors active 3D system

∗ Stacking to get double display area or brightness

∗ Edge Blending to enlarge the display

∗ Support Blue Ray 1080p/24Hz 3D
