ABSTRACT:
A black-white or color television camera comprising a pick-up tube, provided with a signal electrode composed of separated strips. Prior to a line scan to be performed by an electron beam, the signal electrode strips are connected to a reference potential. After a scan the strips are through-connected successively through associated switches for supplying information. The switch outputs are alternatingly, in at least two groups through-connected and connected to at least two output leads. Always two stitches, which are connected to two adjacent strips are closed simultaneously. In this way it is avoided that a capacitive voltage distribution across the strips and switch inputs influence the picture signal obtained in a disturbing manner.
