The SVC-Beta Camera is for video professionals who want to create content for stereo-vision productions.  The SVC-Beta may be used with StereoGraphics Corporation's video equipment for viewing on a monitor or for projection on a large screen.  It may also be used as a video source for  head-mounted-displays.  Images can be recorded on a single standard tape deck, or on two decks.

The camera is an integral unit for videography made up of two Sony 930 high resolution camera heads, and is available in either NTSC or PAL.  The lenses are 6.7 to 107mm Fujinon zoom optics.  The camera heads and lenses are mounted on a rugged optical-bench design which will hold tolerances to better than 1/1000 inch.

The motorized camera functions are interlocked and are operated from the camera or remotely.  The variable speed zoom, focus. and aperture are electronically set. The aperture may be set manually or by automatic aperture.

In addition to these conventional camera controls the product has two unique stereo-vision controls:  The distance between the two camera heads (interaxial setting) may be varied from between three to eight inches, to strengthen or weaken the stereo-vision effect.  In addition the camera may be adjusted to place the desired object in the plane of the display screen (zero parallax setting, ZPS). In this way the operator may position objects beyond the plane of the screen, virtually into the viewer's lap.  Both of these functions are motorized.

The camera offers a special interlocking control system giving the videographer the option of linking focus and ZPS.  In this way the object of principal interest remains in the plane of the screen as the operator pulls focus.  The focus and ZPS controls may be operated independently.

The color viewfinder may be used in any one of several modes:  Stereo without reticule, stereo with reticule, left, right, and left and right mixed.  The ability to view with stereo-vision is a rare feature for a stereoscopic camera.  The reticule is a cross-hairs reference used to place the desired object in the plane of the screen while viewing with stereo-vision.  The ability to view the output of each head independently is valuable for checking the reliability of the heads.  The mixed mode also serves as a reference for placing objects at the ZPS, and when the focus and ZPS are linked, it serves as a coincidence range-finder.

Thus the output of the camera may be plugged directly into a Beta deck with no additional electronics package in-between the camera and deck needed for producing StereoGaphics multiplexed side-by side format.
