Abstract

Abstract A high quality non-interlaced television signal is generated without using a large size circuit. Interlaced television signals are obtained from four image pickup devices. A luminance or green signal in the interlaced television signals consists of two interlaced channels. These two channel luminance or green signals are simply combined to produce the non-interlaced signal without modifying the driving frequency of the image pickup devices.
