ABSTRACT:
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.
