Abstract: A 3D image capturing and playing device includes: a 3D image capturing module, an audio capturing module, a control unit, and a video playing module. The 3D image capturing module, which includes a first image capturer, a second image capturer, and a frame composer, captures a 3D image of an external object and converts the 3D image into a digital image signal. The video playing module includes a display converter, a DLP projection engine, a liquid crystal display (LCD), and a synchronous signal emitter. The 3D image capturing and playing device not only has the two horizontally aligned image capturers for capturing the 3D image, but also is built-in with the DLP projection engine and the LCD for projecting or directly displaying the 3D image. Hence, the device is self-contained and easy to operate, thereby meeting the consumer need of taking, playing, and projecting 3D images.

Abstract: A multi-region light scattering element with the optical characteristics of low speckle, high resolution high contrast, and high gain when used as an imaging element without any resulting loss of transmission or brightness with viewing angle. The multi-region light scattering element contains at least one region asymmetrically shaped light scattering features that are separated from a second light scattering region by a non-scattering region. In one embodiment, one or more of the regions contains particles that are asymmetrically shaped that improve the optical performance. In one embodiment, asymmetric particles are located in two regions separated by a non-scattering region with the particles within each region substantially aligned along an axis and the two axes are substantially perpendicular to each other. Methods for production of the screen element are also described.
