ABSTRACT:
The present invention relates to a noise reduction and signal compensating circuit for video imager which compensates a received picture image of a high density television or general television and permits reception of a clean image without noise, and reduces the deterioration in quality of a reproduced picture image which is attributed to a variable reproduction speed in a video cassette recorder (or video disk player).
Accordingly, this invention provides an automatic picture quality compensating circuit which has an automatic picture quality compensating means to create a clean picture image by improving sharpness and removing noise components contained in the picture image.
