Design of 3D Mobile Phones and Application for Visual Communication

This paper discusses realization of 3D mobile phones in respect of acquiring stereo images and displaying them. The parallel and radial types as 3D imaging layouts and autostereoscopic 3D displays are realized and their experimental results are compared. This paper proposes that when a mobile is equipped with a single camera the radial type has an advantage for taking stereo images satisfying fusible 3D images in a short distance because it has a permissible disparity in a arm length specially only. However, when a mobile phone is equipped with a pair of cameras the parallel-type has more advantage in that it offers a large fusible area in providing 3D depth cue to viewers relatively. A slanted parallax barrier generates viewing zone to the viewer without Moiré effect, but the complexity of the structure causes computational burden for image display. To testify 3D mobile visual communication stereo images are transmitted over CDMA mobile networks and the experiment is successfully accomplished keeping an acceptable image quality and 3D effects.
