摘要： An image pickup tube is provided with the third electrode to control the potential of the region which is not scanned by an electron beam in the image pickup tube target section including a target electrode and a photo-conductive film. A method for operating this image pickup tube is also disclosed. Thus, undesired image phenomena which are generated when the image pickup tube is used with a relatively high target voltage, e.g., image distortion, shading, a waterfall phenomenon and image inversion phenomenon can be suppressed, thereby realizing a high sensitivity image pickup tube.

摘要： The present invention relates to a method and an apparatus for driving image pick-up tubes in, particular, a color television camera or the like having more than one image pick-up tube and in particular to a method and an apparatus for driving image pick-up tubes in which the potentials of the cathode electrodes of the respective image pick-up tubes are set to the same common potential, the potential of the target electrode of at least one of the image pick-up tubes is set substantially to earth potential, target drive potentials are individually applied to the target electrodes of the other image pick-up tubes, and the target potential of each image pick-up tube is set to a value near the earth potential, so that a high S/N ratio is obtained. The driving appartatus can be miniaturized and easily driven. According to the invention, a capacitor, such as a chip capcitor or the like, with a low withstanding voltage can be used in a first-stage amplifier to amplify the video signal from the target electrode. This first-stage amplifier can be arranged near a signal output electrode of the target. Thus, the stray capacitance can be reduced.

摘要： In a target structure for use in a photoconductive image pickup tube, a P-type photoconductive film is deposited on an N-type transparent conductive film which is deposited on a transparent substrate. The P-type photosensitive film comprises first and second photoconductive substances. The commencement of the deposition of the first photoconductive substance is delayed a predetermined time from that of the second photoconductive substance thereby forming a film of the first photoconductive substance which is not contiguous to the junction surface between the N-type transparent conductive film and the P-type photoconductive film.
