I met with Fujifilm Canada last week to go over their fall lineup of cameras and got to play with the new 3D camera. Pretty cool stuff, but not that practical.
On the one side you don't have to wear the silly 3D-movie glasses to view the effect, but then you can only display the 3D picture either on the back of the camera LCD or on a special 3D digital picture frame.
I would expect this technology (display-wise) to rely on high-speed, selective crop, alternation of two images at one-half the refresh rate, essentially interleaving.
They probably compare the images and detect the "pop-outs" as the backgrounds will be really similar, but the near-field subjects won't. Then they might combine this interleaving with a polarizing mask on the LCD.
