PROBLEM TO BE SOLVED: To provide a high resolution screen free from smears speedily without providing any shutter by providing an electronic image pickup tube, which is provided with pixels with a specific dimension and performs scanning and focusing by means of electron beams for an optically formed image on a photosensitive target consisting of monocrystal semiconductor material so as to output an electric signal, a control means for the electronic image pickup tube, and a signal storing means. SOLUTION: In a photosensitive target 6 in a monocrystal semiconductor with a thickness of 300mμor more, a matrix of pixels, which occupy a surface area of less than 10μm<2> and are provided with small capacitance, is formed, and high frame speed and resolution are provided. An image of a scene 12 is formed on the target 6 by means of optical means 10, and its scanning and focusing are carried out with electron beams 16 from an electron gun 14 according to electrostatic scanning controlled by means of a first electronic processing means 20 and by means of focusing means 18, and then, an electric signal S is outputted. A signal S from an electron image pickup tube 4 is stored in controlling-storing means 22 controlling the processing means 20, and an image is displayed by means of a display means 26 after processing by means of a second electronic processing means 24 is carried out.
