3-D Movie Camera

Normally you need a special camera with two lenses to take 3-D photos. Intelligent Gadget's 3-D Movie uses the motion of the camera, or the motion of objects relative to the camera, to generate the 3-D effect - known as "structure from motion" in geekspeak.

Seeing 3-D

With the recent popularity of 3D viewers for gaming and other applications one assumes such devices are essential for viewing 3-D media. As it turns out, with a little training anybody can see 3-D without viewers, glasses, or other devices. Let's start by viewing the photo below in 3-D.

Hold your mobile device at arm's length and look over the top of the screen at a distant object. Without lowering your gaze notice the two images now seem to overlap to form a third image between them. Keeping your eyes relaxed and focused in the distance, shift your attention (but not your eyes) to that third, middle image. When the correct gaze is achieved the horizontal and vertical bars will overlap to form a "+" sign and the image appear three-dimensional.

 

Capturing 3-D Movies

Press the camera icon to start recording a 3-D movie. Press again to stop the movie and store it in the camera roll. To capture moving objects like fish swimming, place the camera on a fixed surface, or for moving objects, you can move the camera smoothly left to right or right to left. The faster you move the camera, the greater the 3-D depth. You can also increase the depth by pressing on the screen to reveal a frame delay icon. Tapping it increases/decreases the frame delay, which increases/decreases the amount of parallax (depth).

N.B. Only objects moving left/right create the depth effect. Objects rising or falling will not appear three-dimensional unless they are also moving left or right.

While capturing a movie, the app automatically determines the camera motion, and renders the movie as two side by side frames. Objects moving in the principal direction of motion appear closer to the viewer while those moving in the opposite direction appear to recede.

As shown above, the 3-D camera can capture movies in portrait as well as landscape mode.
