Three-dimensional television system and transmitter suitable therefor

Claim 1

A three-dimensional television system comprising a transmitter having a picture pick-up arrangement, a receiver incorporating a picture display device, and a signal transmission system arranged between the transmitter and the receiver, the picture pick-up arrangement comprising first and second picture pick-up devices for recording a scene from different positions, the picture display device having a color picture display screen for displaying in two different colors, information intended for a left and a right eye, respectively, of an observer, the items of information being contained in first and second subpictures, respectively, which are shifted in the direction of line scan, which, when the overall picture is observed with two eyes through spectacles having glasses of different colors, results in a three-dimensional picture, characterized in that said signal transmission system is suitable for signal transmission coded in accordance with the PAL, NTSC or SECAM-standards for which purpose the transmitter comprises a matrix-coding circuit and the receiver comprises a decoding-matrix circuit, both incorporating signal channels for processing color difference signals and a luminance signal, an output of the first picture pick-up device in the picture pick-up arrangement being coupled to at least one input of the matrix-coding circuit via a first low-pass filter, an output of the second picture pick-up device being coupled to at least one further input of the matrix-coding circuit, the first low-pass filter having a bandwidth which is not more than the bandwidth of the color difference signal channels in the decoding-matrix circuit of the receiver.
