Multi-view capture technology, which is used to film movies and television in 3D, utilizes an array of many cameras to capture images for redistribution into a multiple view format.
Anaglyphic 3D viewing is accomplished by the viewer wearing passive red and cyan lens glasses to see the images in three dimensions. Polarization 3D viewing transmits the images to viewers who are able to see in three dimensions by wearing passive polarized lens glasses. Alternate frame sequencing requires the wearing of glasses with lenses that include active shutters that allow the viewer to see traditionally two dimensional images in three dimensions. Passive glass systems: Hyundai is developing this type of LCD monitor which will allow both 2D and 3D images to be viewed. To watch the 3-D images, viewers will need to wear the traditional glasses in order to watch three dinemsional media. This technology is nothing new: the TV has two overlapping images and the glasses have polarized lenses. This technology is very feasible and 40 to 50 inch LCD TVs with this technology are currently available for purchase.
Active glass systems: This system is very similar to the passive glass system, except rather than the TV doing all work, the glasses do. The glasses synchronize with the refresh rate of the TV, then they alternate the polarization of each lens, making the wearers of the glasses see 3-D images. Head-tracking, to date, only allows a single viewer to see the display in proper three dimensions. Multiple view technology is considered more commercially viable, as it allows multiple viewers to see the same image in three dimensions, regardless of where they are sitting in relation to the display.
Autostereoscopic displays, or auto 3D, relies on transmitting images to the viewer in 3D without the viewer needing to wear specialized glasses to see the effects. There are two individual technologies associated with auto 3D, head-tracking and multiple view transmission. Head-tracking keeps a location on where the viewer is looking to ensure each eye is seeing a different image in order to transmit a picture in three dimensions. This is different from the multiple view transmission method of delivering 3D images does not need to know where the viewer's eyes are directed in order to transmit images in three dimensions.
