Abstract
A linescan camera is used in conjunction with a mechanical scanning mechanism to acquire high-resolution images of an area under video surveillance. The video signal from the linescan camera is converted into a digital data stream, compressed, and stored in a digital memory. Under control of an operator, full-field images are selectively recalled from the digital memory and converted to a lower resolution for display on a monitor. The operator selects a region-of-interest from the full-field display through the use of a computer pointing device, such as a mouse. The selected area is then displayed on the monitor in its full acquired resolution, thereby allowing the operator to view high-resolution images of a large area under surveillance.
