Glossary of 3D Terms
3D - A three-dimensional medium, display, or performance, especially a cinematic or graphic medium in three dimensions.
JPS – Stereoscopic JPEG file. A stereoscopic image file format that is based on JPEG compression. Used by DepthCharge & other stereoscopic imaging applications.
Multiplex – the process of taking a right and left image and combining them with a multiplexing software tool or with a multiplexer to make one stereo 3D image.
Stereoscopic 3D - two photographs taken from slightly different angles that appear three-dimensional when viewed together
Anaglyph - moving or still pictures in contrasting colors that appear three-dimensional when superimposed. Anaglyph works well for printed matter or computer display, but color problems inherent in NTSC displays (normal TV) result in poor 3D broadcasts.
Row Interleaved – A format to create 3D video or images in which each row or line of video alternates between the left eye and the right eye (from top to bottom).
Passive Polarized 3D glasses – 3D glasses made with polarizing filters. Used in conjunction with a view screen that preserves polarized light.
3D Shutter Glasses - 3D glasses made with electronic liquid crystal shutters. Does not require polarized light preserving screen.
IR Transmitter – A device that sends synchronization signals to wireless shutter glasses.
3D Adjustment Setting – Changes the apparent depth of objects on a 3D view screen.
Column Interleaved format – The 3D image format used by the VR-4200 projector. Left and right view image data are encoded on alternate columns of the display.
Ghosting – A condition that occurs when the right eye sees a portion of the left image or vice versa causing a faint double image to appear on the screen.
Crosstalk – See ghosting.
Field Sequential 3D Video – The most common format for 3D video. Left and right image data are encoded on alternate field of the standard video signal.
3D Format Conversion– For the VR-4200: The process of converting field sequential 3D video into column interleaved image data.
Pseudo Stereo – The effect produced when the left view image and the right view image are reversed. This condition causes a conflict between depth and perspective image.
