ABSTRACT:
This invention provides a method of providing TV surveillance without the need for cumbersome pan and tilt mechanisms. The method involves underscanning a conventional TV camera and dynamically moving the resultant reduced size raster over the photo conductive surface. Movement of the raster over the photo conductive surface emulates the vertical and horizontal movement provided by the pan and tilt mechanism.
