Our vision is binocular, and there are 3D displays, and 3D cameras, that implement two-image recordings.
But, from stereo microscopes, we can also get real-time viewing of a three-dimensional object. What are the camera/display options for implementing a good quality realtime stereo video image?
Even for a monocular image, the options are ... odd. There are a few monocular camera/display options, using composite video for a telescope/microscope/rearview camera and low-quality display, but for higher quality imaging, it's all still photography or record/playback solutions. Or, VERY high prices for 'industrial video'.
Is there some compelling reason that a photoframe with a USB type A socket cannot accept a USB video camera? Or that a stereo microscope cannot display to a 3D television type display?
Other than computer-in-the-middle, that is. Keyboard, mouse, disk operating system, etc. are just IN THE WAY when you want a point-and-watch solution.
