US 6,473,134 B1 · Television receiver that detects electric field information from a received television signal and stabilizes a detected synchronizing signal according to the electric field information

Abstract

A television signal receiver has: receiving means for receiving a television signal; detecting means for detecting a pulse of a video signal obtained from the receiving means; phase detecting means for detecting the phase of the pulse; video signal stabilizing means for conducting image-stabilization on the video signal obtained in the receiving means, in accordance with control information obtained from the phase detecting means and based on the reception disturbance state; and displaying means for displaying a video signal obtained from the video signal stabilizing means. According to this configuration, therefore, the video signal can be stabilized by the video signal stabilizing means, so that disturbance of an image can be reduced.
