Title: Clamp device
Inventor: FUJII KUNIHIKO
IPC: H04N5/922
Filed: 1990-11-22
Abstract: PURPOSE:To always keep a DC level of a video signal accurate by using a digital clamp circuit so as to correct DC fluctuation and level fluctuation at quantization of an A/D converter not eliminated by an analog clamp circuit. CONSTITUTION:An analog video signal inputted to an input terminal 1a is clamped by an analog clamp circuit 10 so that a SYNC tip or a pedestal level is a constant voltage. Then the clamped signal is converted into a digital signal by an A/D converter 11 and inputted to a digital feedback clamp circuit 12, in which a SYNC tip level of the video signal at an output terminal 2b is detected by a SYNC tip level detection circuit 21. Thus, the dynamic range of the A/D converter 11 is effectively used by employing both the analog and the digital clamp circuits and the quantization level of the SYNC tip is always kept constant.
