METHOD AND DEVICE FOR MEASURING NOISE LEVEL, WHICH CORRESPONDS TO SIGNAL NOISE

摘要

digital TV signal processing for TV equipment. SUBSTANCE: noise level corresponding to noise in signal is used for controlling noise suppression filters, as well as other digital signal processing circuits, in particular, image quality improvement circuits. This results in possibility of facilitated use of image improvement algorithms used in modern digital TV sets. EFFECT: possibility to detector noise in signal, improved picture. 9 cl, 4 dwg
