Description

St efglevzionny system

The proposed technical relates to television technology, in particular, to closed-circuit television systems - white stereo television, and can be used in industrial television systems, as well as to create broadcast stereo television systems.

Closest to its claimed technical solution to the claimed one is a stereo television system with a nosledovatelkhoy broadcasting of stereo signals (G.V. Mamchev, Stereo TV, Moscow, Eergiya, 1979, p. 21). It contains two transmitting television black-and-white cameras, an electronic switch, the inputs of which are connected to the TX & REC outputs of the television black-and-white cameras, an intermediate and terminal video amplifier, a monitor, eclipse-type glasses for viewing the monitor, and a syncrogenator, whose output is parallel connected to the inputs of non-fading black and white television cameras, its second output is connected to the monitor synchronization input, and the third & output is connected to the control input of the eyewear glasses. In this system, the electric switch alternately with the period of the fields commutes the video signals from two cameras, which are sequentially fed into the monitor; individual frames (fields) of the stereo pair are alternately played back on the screen. At the same time, in order for the eye to notice flicker when observing stereo images, the frequency of the change of frames (fields) in the iggo system should be 2 times higher than the frame rate in a conventional television broadcast system. This is the main disadvantage of this system.

The objective of the proposed technical solution is to improve the quality of stereo television images displayed in a broadcast television standard without an increased frame rate.

This is achieved by the fact that a schereotelevision system containing two transmitting television black and white cameras, an electronic switch, to the inputs of which are connected the outputs of non-transmitting black and white television cameras, a monitor, viewed through eclipse glasses, and a clock generator, the first output of which is connected in parallel with the inputs of the black and white . black and white television cameras, its second output is connected to the input of the monitor’s synchronization, and its third output is connected to the control input of the eclipse glasses, characterized in that the monitor is color, the system is equipped with a shaper having three outputs of television signals, the span of which corresponds to 30: 11: 59 connected to the control inputs of the color monitor, while the inputs of the shaper are connected respectively to the outputs of the electronic switch.

Presented in FIG. a functional diagram of a stereo television system explains the essence of the proposed technical solution. It is indicated here:

22, 23 - standard p) traveling television black and white cameras;

32-electronic switch;

33-shaper;

42 - standard color monitor;

52 - a clock generator;

62 - eclipse stereo glasses, switchable by color (spectrum).

The stereo television system contains two transmitting television black and white cameras 22 and 23, an electronic {yumutator 32, to the inputs of which the outputs of the transmitting television black and white cameras 22 and 23 are connected. The outputs of the electronic switch 32 are connected to the inputs of the driver 33 having three outputs E Е and ЕЗ television signals connected respectively to the control inputs R, B, G of the color monitor 42. Synchronous operation of the stereo television system is provided by the sine generator 52, the first output of which is connected in parallel with the inputs Pass the television black - white cameras 22 and 23, its second output connected to an input sync color monitor 42, through the under review eklipsnye stereoscopic glasses 62, and the third clock output 52 connected to an input control eyushnsnyh stereoscopic glasses 62 with LCD - cells.

Shaper 33 is made in a video resistor matrix that converts the output signals of transmitting television black and white cameras 22 and 23 EP EL Е, as a result of which signals are output from three outputs of the formovagel, the magnitude of which EI, Е2, ЕЗ correlates as 30: 11: 59.

The proposed device operates as follows.

Formed by the fields (even and odd) and the span of EI EI, EZ, aux video signals are supplied to the corresponding R, B, G control inputs of the color monitor 42 operating in the broadcast standard. With this method of forming a black and white stereo television image in each field (even and odd)

always at the same time three monochromatic (R, B, G) images are depicted with the corresponding contrasts and brightness reproduced on the color monitor screen (for the observer's left and right eyes) in the sequence (from zero to zero) indicated in the table.

Table

The stereo television image displayed on the screen of the colorful monitor 42 is monitored with the help of stippled stereo glasses 62, with successively switched eyepieces with LCD cells (left, right) synchronously with the artificial image of the stereo stereo on the screen of the colorful monitor with a frequency of 50 Hz. Switching the eyepieces of the eccipsic stereo-eyewear) B is performed according to the instructions of the oscillator 52.

The proposed device is PERFECT tested and showed high quality stereo playback.
