Abstract
A surveillance apparatus for use in a camera surveillance system, the surveillance apparatus being microprocessor controlled and including an image blanking unit provided to establish privacy zones in which the video images of the surveillance apparatus are partially or totally blanked out to obscure viewing by an operator. The privacy zones are established by designating triangular areas of the image.
Claims18
A surveillance apparatus for use in a camera surveillance system, the surveillance apparatus comprising:
- a camera and lens assembly capable of panrung, tilting and zooming, said camera and lens assembly generating an output video signal corresponding to an image in the field of view of said camera and lens assembly;
- an image blanking unit receiving said output video signal and modifying said output video signal to one of partially and totally blank portions of said image, said blanked portions of said image corresponding to preselected privacy zones;
- and
- a control unit for controlling the image blanking unit responsive to one or more of the pan, tilt and zoom conditions of said camera and lens assembly.
A surveillance apparatus for use in a camera surveillance system, the surveillance apparatus comprising:
- a camera and lens assembly capable of panning, tilting and zooming, said camera and lens assembly generating an output video signal corresponding to an image in the field of view of said camera and lens assembly;
- and
- an image blanking unit receiving said output video signal and modifying said output video signal to one of partially and totally blank portions of said image, said blanked portions of said image corresponding to preselected privacy zones, said image blanking unit being formed by a text overlay unit for providing a text overlay signal on the output video signal.
A surveillance apparatus for use in a camera surveillance system, the surveillance apparatus comprising:
- a camera and lens assembly capable of panning, tilting and zooming, said camera and lens assembly generating an output video signal corresponding to an image in the field of view of said camera and lens assembly;
- an image blanking unit receiving said output video signal and modifying said output video signal to one of partially and totally blank portions of said image, said blanked portions of said image corresponding to preselected privacy zones;
- and
- a unit for generating information as to the azimuth and elevation angles of said camera and lens assembly for display with the image corresponding to said modified video signal.
