The mobile device has the lacked space for configuring cameras to make either ortho- or hyperstereoscopic condition with a small size of display. Therefore mobile stereoscopy cannot provide a presence with a good depth sense to an observer. To solve this problem, we focused on the depth sense control method with a switchable stereo camera alignment. In converging type, the fusible stereo area becomes wider compared to a parallel type when the same focal length was used in both types. This matter makes it that the stereo fusible area formed by converging type to be equal to the parallel type with a more shorten focal length. Therefore there is a kind of the zoom-out effect at the reconstructed depth sense. In diverging type, the fusible stereo area becomes narrower than the parallel. As the same way, the diverging type guarantees a similar characteristic of that an increased focal length is considered in parallel type. Therefore there is a zoom-in effect existing. Stereoscopic zoom-in depth effect becomes rapidly changed by the increased angle but zoom-out becomes retarded relatively.
