Abstract

PARA OBTENER UNA SALIDA DE REFERENCIA DE LA CUAL SE ELIMINEN LA DENSIDAD NO UNIFORME Y LOS PATRONES FIJOS DE RUIDO UTILIZANDO PIXELS OB (1) EN UN DISPOSITIVO DE ESTADO SOLIDO DE CAPTURA DE IMAGENES, ESTE DISPOSITIVO TIENE MULTIPLES UNIDADES DE ALMACENAMIENTO (3) PARA ALMACENAR LA SALIDA DE SEÑALES DE PIXELS DE MULTIPLES ELEMENTOS DE CONVERSION FOTOELECTRICA (11), QUE ESTAN FORMADOS EN UN SUSTRATO SEMICONDUCTOR Y EN EL QUE AL MENOS DOS DE ELLOS ESTAN PROTEGIDOS DE LA LUZ, EN CORRESPONDENCIA CON LOS ELEMENTOS DE CONVERSION FOTOELECTRICA. LAS SALIDAS DE SEÑALES DE PIXELS DE LOS ELEMENTOS DE CONVERSION FOTOELECTRICA PROTEGIDOS (1) SE SOMETEN A UN PROCESO DE PROMEDIADO EN LAS UNIDADES DE ALMACENAMIENTO. ADEMAS, EN EL DISPOSITIVO DE ESTADO SOLIDO DE CAPTURA DE IMAGENES, LAS UNIDADES DE ALMACENAMIENTO ESTAN FORMADAS POR CONDENSADORES (3), QUE ESTAN ELECTRICA Y TEMPORALMENTE CONECTADOS ENTRE SI (5) PARA LOGRAR EL PROCESO DE PROMEDIADO.
