Sony Cyber-shot DSC-TX9

Instead of using an add-on lens or two lenses and sensors, Sony just took advantage of its high-speed processor and sensor to create 3D images. The TX9 as well as the Cyber-shot DSC-WX5 feature a 3D Sweep Panorama mode. Press the shutter release and as you sweep the camera up, down, or sideways it shoots separate photos for the left and right eyes. It then creates a single 3D image that's viewable on a 3D-enabled HDTV.

The cameras also have a Sweep Multi Angle mode, which works similarly by taking 15 photos at different angles as you sweep across a scene. The camera then coverts those into one photo. By tilting the camera back and forth during playback, the camera's built-in gyro sensor displays the image in a 3D-like view on the camera's LCD. It's akin to viewing a lenticular photo. Of course the big problem is that they're only viewable on the camera.
