Geo Tahoe

post #1 of 9
Thread Starter 
I recently saw a new device that has some interesting applications for projectors. It is called the Geo Tahoe. I don't believe there are any devices out there using it right now, but hopefully there will be soon. It looks like it could correct for pixel misalignment and chromatic aberration. Another cool feature is the ability to shape the image for those needing keystone or wanting a curved screen. A Torus may now be possible with a digital. Peter are you listening.

Driven by the powerful Geo processor, the Tahoe evaluation board provides advanced
geometry processing features, such as correction for lens distortion and lateral
chromatic aberration, geometry distortion, and rotational misalignment. With up to 16-bit
internal processing for each channel, Geo can achieve color convergence at 1/32 pixel
calculation accuracy and rotational correction with a resolution of better than 0.1o. Geo
also supports up to +/- 70o Horizontal keystone correction, +/- 70o Vertical keystone
correction, and +/- 10o Tilt correction.

Or maybe for stacking projectors.

Sounds like it would be a lot like sub-pixel alignment tools some projectors have (allowing shifting a color by <1 pixel), or digital keystone correction. Sounds great in theory, but in practice just makes everything softer, because you end up simulating one pixel with more than one.

When i first saw the thread i thought it was a hybrid between the Geo and the GM Tahoe. That would be one weird looking car.

You are right, it would be great for curved screens assuming it doesnt make the image softer

Yes, this could be very good for stacking. Maybe a stack and a blend.

You can shift the individual color images as much as you want. I didn't notice any softening, but it wasn't a long demo.

It would be nice if you could purchase this devise on a per basis but it looks like a volume OEM for manufactures only.

If you are a manufacturer you can get an evaluation board.

I was hoping that maybe one of the boutique builders might try to do something with it.

Why? Another way for them to go broke.
