An economical color-television camera utilizing a silicon vidicon for electronic color separation

A new image device designed to electronically separate two kinds of color components from an optical image utilizing photoelectric properties of the surface of a silicon-vidicon target, and an economical color-TV camera using this device are proposed. This system requires neither special construction of a camera tube target to obtain index signals for color separation nor bias lighting. Crosstalk components present in the color signals from the color camera tube are corrected by circuitry. This color camera is about three times as high in sensitivity as that using an antimony trisulfide vidicon. It has many other features, including the capability of imaging a fixed object, without burn-in for a long time, as well as high reliability and long life.
