Abstract
A television receiver has a video muting processing function wherein a blanking added video signal is produced by superimposing on a video signal a blanking signal gradually varying in the width in the time direction and consists of a composite signal in which blanking signals are superimposed respectively on the front edge and rear edge of the video signal part.
Claims3
A video displaying apparatus capable of displaying a video while forming a blanking region adjacent to the video displaying region, said video displaying apparatus comprising:
- a video signal source for providing a video signal;
- compressing means for compressing said video signal in a predetermined time direction, thereby converting said video signal to a compressed signal;
- blanking signal generating means for generating a blanking signal gradually varying relative to a width of said blanking region;
- superimposing means for superimposing said blanking signal on a vacant region produced by compressing said video signal, thereby producing a blanking added video signal;
- and
- driving means for displaying a video corresponding to said blanking added video signal produced by said superimposing means.
A video displaying apparatus capable of displaying a video while forming a blanking region adjacent to the video displaying region, said video displaying apparatus comprising:
- a video signal source for receiving and processing a television broadcast signal and for producing a video signal based on said processed television broadcast signal;
- signal generating means for generating a blanking signal which gradually increases in blanking width toward a picture center from at least one of the horizontal and vertical directions, said blanking signal being generated in response to a video mute;
- superimposing means for superimposing said blanking signal on said video signal produced by said video signal source;
- and
- means for displaying an image corresponding to said video signal to which said blanking signal output from said signal generating means is superimposed.
A video displaying apparatus capable of displaying a video while forming a blanking region adjacent to the video displaying region, said video displaying apparatus comprising:
- a video signal source for receiving and processing a television broadcast signal and for producing a video signal based on said processed television broadcast signal;
- means for indicating a release of a video mute;
- signal generating means for generating a blanking signal which gradually decreases in blanking width toward at least one of horizontal and vertical directions relative to a central region within said video displaying region, said blanking signal being generated in response to said indication of video mute release;
- superimposing means for superimposing said blanking signal from said signal generating means on said video signal from said video signal source;
- and
- displaying means for displaying an image corresponding to said video signal to which said blanking signal output from said signal generating means is superimposed.
