MasterImage 3D is a company that develops stereoscopic 3D systems for theaters and auto-stereoscopic (glasses-free) 3D displays for mobile devices.

Technology

Stereoscopic viewing is based on delivery of slightly different images to each eye. MasterImage 3D's system for cinemas is based on the projector alternately flashing frames for each eye at high speed. This is similar to the system used by the competing brand RealD 3D. However, while RealD uses an electronic optical filter which "flips" back and forth between two types of polarization, MasterImage uses a large spinning filter, containing alternating segments of circularly polarized material, mounted in front of the projector lens and synchronized to the projected images. The filter wheel lowers out of the optical path for non-3D material.[1] The MasterImage 3D filter wheel spins at a very high speed and it has been noted that an earlier version of this filter malfunctioned, but the problem has been addressed with an updated replacement filter which was supplied to all theaters using the system.[2]

Auto-stereoscopic viewing is also based on the ability to deliver slightly different images to each eye. MasterImage 3D's auto-stereoscopic displays deliver this effect without the use of 3D glasses to screens ranging from 3 inches to 10 inches. MasterImage 3D achieves the effect through its patented cell-matrix parallax barrier technology, which uses a cell gap approach that enables landscape and portrait modes, provides a 10 degree viewing angle, and reduces the Moire pattern that causes ghosting. MasterImage 3D's auto-stereoscopic display was used in one of the world's first glasses-free 3D mobile phones, the Hitachi Wooo, available in Japan in 2009. MasterImage 3D also develops a 3D camera ASIC that enables users to create 3D content.
