Interactive method and apparatus for producing three-dimensional television wherein means having a computer and stored program device feeds a standard television monitor with two separate signals to produce a stereographic display in different colors that can be viewed through separate colored filters for three-dimensional television viewing by a large number of people.
In a method for simulation of a field of view for battle training individual images of a terrain, targets, trajectories of projectiles and sights which are digitally stored in memories (10-16), after combining and digital/video conversion in an image synthesizing device (20), are displayed on a TV monitor (TVM). The images are stored as right and left half images, and they are displayed in a half image interlaced scanning. For simulation of a stereoscopic range meter preferably the sight memory (16) stores two half images of a stereoscopic index mark in addition. The image displacement of both half images is controlled as a function of range and a viewing unit (DO, BT1, BT2) serves to feed both half images on the TV monitor (TVM) to the eyes of the spectator (FIG. 4).
An improved stereoscopic television system is disclosed, having a great deal of compatibility with the existing commercial television infrastructure. Flicker is eliminated while preserving the existing bandwidth allowing the stereoscopic video signals to be handled with conventional apparatus such as video tape recorders, video disks, or broadcast equipment. In the present invention the number of fields per second is twice that of he standard field rate. When displayed on an unmodified receiver or monitor, each subfield image appears to be anamorphically compressed in the vertical direction by a factor of two. A blanking area and/or vertical sync pulse separates the two subfields.
In a television system, a multiplexing system permits the simultaneous transmission of two or more images with apparent full resolution, but without a corresponding increase in required transmission bandwidth. The television transmission uses the method of interleaving successive scan lines from different picture sources, such as two TV cameras, these sources being synchronized by common horizontal and vertical synchronization signals.
A system and method for producing rapid, high resolution hard color copies from computer-based graphics and image processing including a computer-controlled color video signal graphics system for producing electronically generated digital character and/or graphics data in response to programmed commands that are input to the graphics system. Thereafter, the graphics system transforms the digital data into blue, green and red color video signals which are input to a color camera system through a color control panel that is controlled by a microprocessor. The color control panel sequentially switches each of the red, blue and green video signals through to a video monitor where the signals are transformed into video images on a screen of the monitor. The video images appearing on the screen of the monitor are filtered by a color filter wheel which is also controlled by the microprocessor of the camera system. One of two types of film may be selected for exposure to the filtered video images. The video images are timed by the microprocessor so that the film medium will be exposed to each of the filtered video images for the proper length of time required to sensitize the film for each particular color of video signal. The color control panel of the camera system may also be operated to meter the brightness of the video images appearing on the screen of the monitor and to thereafter adjust the contrast and brightness of the video images.
A 3-dimensional color television system in which left and right images are always displayed simultaneously and where the colors of each of the left and right images are alternately switched.
