Sony develops single-lens 3D camera

Set to be unveiled at next week's Ceatec show

Sony has developed a movie camera capable of shooting 3D images with a single lens and plans to unveil it at next week's Ceatec show in Tokyo.

By using a single lens the camera neatly solves one of the problems associated with current 3D photographic technique: the complicated set-up required for dual lenses. When using a camera with two lenses - one for the right image and one for the left - the lenses must be carefully aligned and synchronised so that the resulting images maintain the same degree of 3D perception when see by viewers.

The Sony camera takes a single image and separates it into right and left images that are then recorded by individual image sensors. The light is split using mirrors, not shutters, so the recorded image also appears smoother, said Sony.

3D imaging is a hot topic in the consumer electronics industry at present. Sony and Panasonic both said in early September that they plan to launch 3D televisions in 2010 and Sony said it would also add 3D technology to its PlayStation 3 games console.

However other manufacturers are slightly cooler on the idea and have indicated they'll wait and see how the technology is received by the public before launching their own products.
