Abstract
Dispositivo para la detección de bordes y mejora de calidad en una imagen que comprende una agrupación de celdas elementales de procesamiento idénticas e interconectadas localmente. Cada celda de procesamiento se caracteriza a su vez por un comparador que lleva a cabo en paralelo la comparación de cada par de pixeles vecinos. La tensión umbral que establece la diferencia de tensión entre pixeles considerados parte de un borde se determina mediante un ajuste temporal de una señal de control. Este ajuste, junto con el de la señal de control de filtrado, también de carácter temporal, son los únicos necesarios para configurar el procesamiento deseado. No se requieren señales analógicas externas de control por lo que se facilita la programación del hardware por el dispositivo que se utilice y se reduce el número de convertidores digital/analógico del sistema final.
