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.
