Ok, I posted this an hour ago or so, but it doesn't seem to have shown up, so if there's a double entry, please don't flame me, just delete the second entry.

The idea is this: For 3D live action recordings, you usually put two camera rigs next to each other, just like your pair of eyes, ie stereoscopically aligned.

With the Mysterium Sensor having space for 3.5 images at 720p next to each other at native resolution I think it might work to get two stereoscopic images from it at the same time. That is, you would record a 720p rectangle at the very left end of the sensor and a 720p rectangle at the very right end of the sensor at the same time.

If I do a little math (assuming the sensor being 25 mm wide), this means that the centers of these two images on the sensor would be roughly 15 mm apart from each other - not much, but it should work. After all, little dogs have depth of field perception and their eyes are about that distance from each other.

What's better, it's just a software fix and would give the camera an entirely new field of application - 3D recording.

The more I think about it, the more I like it... Jim, if you read this: I hereby irrevocably waive any rights I might have in this idea but give me a call if you want some legal protection in Europe, I'm an attorney here specializing on intellectual property law... ;)

Ok, looking back at my minuscule knowledge of optics the concept of just doing this by firmware probably wouldn't work. There have to be separate optics.

That said, it would probably be possible for Oakley to build a twin lens that reflects one image on one half of the Mysterium sensor and the other image on the other half of the sensor, thus making 3D recording with one RED body possible. Of course, not nearly as simple a task as just changing the firmware, as I had originally thought.

Just so you know, the normal stereo base interocular (center to center distance between the left and right stereo images) is approximately 65mm.
