Abstract

PROCESADOR DE SEÑAL DE MOVIMIENTO. EL DISPOSITIVO DISPERSA ESPACIALMENTE UNA SEÑAL DE MOVIMIENTO SOBRE UN VALOR ESPECIFICO, DETECTANDO EL VALOR MAXIMO DE UNA VENTANA DE IMAGEN Y A CONTINUACION RECONSTRUYE EL MOVIMIENTO ADAPTATIVAMENTE UTILIZANDO LA SEÑAL DE MOVIMIENTO DISPERSADA DE ACUERDO CON EL AREA DE MOVIMIENTO ESPACIAL DE LA SEÑAL DE MOVIMIENTO. UN CIRCUITO DE VALOR MAXIMO (128) DETERMINA EL VALOR MAXIMO DE LA SEÑAL DE DIFERENCIA DE CUADRO FILTRADA ESPACIALMENTE CON UN FILTRO PASABAJOS, PARA PROVEER LA SEÑAL DE MOVIMIENTO DE CORRELACION ESPACIAL. EL VALOR MAXIMO SE COMPARA CON UN NIVEL DE REFERENCIA PREDETERMINADO MEDIANTE UN COMPARADOR (124). A CONTINUACION, UN DETECTOR DE AREA (130) RECONSTRUYE EL AREA DE LA SEÑAL DE MOVIMIENTO DE LA SALIDA DE SEÑAL DEL COMPARADOR (124), PARA APLANAR ADAPTATIVAMENTE LA SEÑAL DE MOVIMIENTO. UN GENERADOR DE VALOR K GENERA FACTORES DE MOVIMIENTO PROCESANDO LA SEÑAL DE DETECCION DE AREA. POR LO TANTO, LA SEÑAL DE MOVIMIENTO ES DISPERSADA SUAVEMENTE.
