Abstract

A color television camera having an image pickup unit for providing three-color image pickup signals at a predetermined rate fs includes an analog/digital converting unit for digitizing an output signal of the image pickup unit at a clock rate equal to the rate fs, a first rate converting unit for interpolating and converting the rate of the digitized image pickup signals into three-color digital image signals having a rate 2fs, a signal processing unit supplied with the rate-converted three-color digital image signals for forming a digital compositive video signal at the 2fs rate, a digital low-pass filter supplied with the digital composite video signal from the signal processing unit for limiting the frequency range of the digital composite video signal to less than about fs/2, and a second rate converting unit coupled to the digital low-pass filter for converting the rate of the frequency limited digital composite video signal to fs.
