Recent Developments in 3-D Imaging Technologies
Son, Jung-Young,Javidi, Bahram,Yano, Sumio,Choi, Kyu-Hwan IEEE 2010 Journal of display technology Vol.6 No.10
<P>Three-dimensional (3D) imaging technologies that have been developed recently are reviewed. In recent years, many new progresses in the 3D imaging have been made but most of them provide more practical solutions to comply with the commercialization efforts of the 3D imaging. Based on time-multiplexing, revisiting the stereoscopic imaging methods is one of the solutions to make possible each view image has the full panel resolution. The rapid progresses of high speed LCDs and the initiation of stereoscopic imaging service to mobile phones have made the method possible. The efforts also encouraged more concerns in evaluating 3-D image quality and identifying factors affecting the quality. In this respect, in-depth analysis has been done for the multiview imaging methods, and other forms of multiview 3D image display methods, such as the focused image/pixel array of multiview images are also analyzed.</P>
Depth resolution in three-dimensional images.

<P>The depth of field of a camera defines the depth range to be covered by the camera. In 3D images, the resolvable depth range is also determined by the depth of field (DOF). Hence the depth resolution and resolvable number of depth layers obtainable with a given 3D display will be defined within the DOF when the display has the same resolution as the total camera resolution of the array in the horizontal direction. The depth resolution and resolvable number of depth layers are mathematically derived in terms of the circle of confusion. The resolvable number of depth layers is approximately linearly proportional to the camera distance and inversely proportional to the aperture diameter of the camera objective. The accuracies of the derivations are examined experimentally. The results show that the DOF extends slightly and the depth resolution improves up to 20% more than that predicted by theory for the given experimental condition. This means that the depth resolution derived has more than 80% accuracy.</P>
