Abstract
A color television signal generating apparatus has a noise reduction circuit for reducing noise in output primary color signals of a camera tube which has a color-resolving striped filter. The noise reduction circuit operates so that the noise included in the color signals only consists of cosine terms of a first-order noise component when a white or magenta image is picked up by the camera tube.
