One eye can't use sterescopic offset to determine depth. So a one-eyed individual can only approximate depth perception by judging relative size of objects in relation to the viewer, horizon lines and architectural or environmental lines (corners, tiles, any sort of details that diminish the further away they are from the viewer).
But the description of the Sony camera doesn't sound like it "sees" the way a single human eye would. For starters, the lens physically moves "...will be able to capture both 3D and 2D images using a single lens using a sweeping motion" whereas the human eye only pivots/rotates. So once again, it does this from one viewing angle, just like a human, without having to physically move the camera for a perspective shift, or have a second lens to provide that perspective offset from one axis.
