COLOR IMAGE PICKUP DEVICE

PURPOSE:To improve mass productivity in production of a one image pickup tube and one solid-state image pickup element system color image pickup device by using a prism in a color separation optical system, and constituting a device so that a scanning position due to the deflection of an electron beam in an image pickup tube is coincided with the scanning position in a solid-state image pickup element. CONSTITUTION:A color separation optical system prism separates incident light, and green color light is introduced to an image pickup tube 4, and magenta color light to a solid-state image pickup element 5. A horizontal and a vertical clock pulses are utilized, for example, the table of a ROM14 which stores a correction waveform with a system to decide a horizontals and a vertical addresses is used, and a fine grid stripe pattern, etc., is image-picked up in order to detect a scan dislocation easily, and at such a time, the input position of a luminance signal from the image pickup tube 4, that is, a scan position, is compared with the scan position of the solid-state image pickup element 5, and the share of luminance signal in which a position dislocation occurs is DA-converted, and is feedbacked to a deflection circuit in the image pickup tube 4, and a correction for a deflection distortion is performed, and the scan position at an image pickup tube 4 side is coincided with that of a solid-state image pickup element 5 side, and a luminance picture by the image pickup tube 4, and a chroma picture by the solid-state image pickup element 5 are overlapped correctly.
