ABSTRACT: The invention relates to a camera tube, for example a television camera tube, having a semiconductor target which on the side to be scanned by an electron beam comprises a mosaic of electrically conductive regions each determining a picture element and separated from the semiconductor plate by an electrically insulating layer, and a resistive layer extending over the mosaic and the insulating layer. According to the invention the camera tube is characterized in that the resistive layer contacts the semiconductor surface via an aperture in the insulating layer present in each picture element and has a RC time between the scanning time of a picture element and the scanning time of the whole target. -14-
