An All-Electronic Field-Sequential Closed-Circuit Color Television System

T. Nishimura, M. Hibi, I. Mitomo, H. Etani

An inexpensive closed-circuit color television system which has a simple construction and good color rendering properties has been developed. It is a field-sequential system which uses only one vidicon and has no mechanical rotating parts. Three color images are simultaneously projected onto the vidicon surface; the electron beam of the vidicon scans these images on the vidicon target and field-sequential signals are obtained. A triad relay lens system has been developed and adapted for color separation. A unique method is used for generating the vertical sweep waveform for the camera tube. The final resolution obtained in the experimental set was about 280 TV lines.
