-9- ABSTRACT: "Television camera". A television camera for colour television comprises several pick-up tubes (T1, T2, T3) which are arranged substantially horizontally or vertically in the camera. The pick-up tubes (T) each have a mu-metal shield (mu1) against magnetism. Each substantially vertically arranged pick-up tube (T2, T3) has an additional second mu-metal shield (mu2, mu2'), which is absent for the horizontally arranged tube. The second shield may be in the form of a single plate (mu2) overlapping the pick-up tube or two plates (mu2, mu2') arranged on both sides of the pick-up tube and overlapping the tube. Deflection errors, especially in the corners of the television pictures caused by magnetic fields, are reduced to acceptable values.
