摘要：
An image pick-up apparatus is disclosed which includes a target portion (101, 102, 103) having a photoconductive film (103) on a substrate (101) and a target electrode (102) and reads video information converted into an electric signal in the photoconductive film (103) by an electron beam. An insulating region (104) is provided for the target portion (101, 102, 103) such that carrier generated in an ineffective scanned region (a target region corresponding to an area not scanned by the electron beam) does not appear on a surface of the target portion (101, 102, 103).
