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

Dolby)Active 3D system (Shutter)
1. Continuous lights2. Comfortable, less eye
fatigue3. High setup cost, low
glasses cost4. 2x brightness5. No health concern6. Good for children
1. Alternative light2. Flickering, eye fatigue3. Low setup cost, high
glasses cost4. Lower brightness5. Glasses management
issue—clean, recharge6. Health concern
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
