摘要
A digitised analogue half image video signal noise reduction procedure compares line noise levels with reference values or another row in either half image and replaces it by repeating a spatial statistic method selected adjacent row if it has high noise or impulse disturbances. Independent claims are included for signal processing circuits implementing the procedure.
