Abstract
Device for edge detection and quality enhancement in an image which comprises a grouping of identical and locally interconnected elementary processing cells. Each processing cell is characterized in turn by a comparator which carries out in parallel the comparison of each pair of neighboring pixels. The threshold voltage which establishes the difference in voltage between pixels considered to be part of an edge is determined by means of a temporary adjustment of a control signal. This adjustment, along with that of the filtering control signal, also temporary in nature, are the only ones necessary for configuring the required processing. No external analog control signals are required making it easier to program the hardware by the device which is used and reducing the number of digital/analog converters of the final system.
