Abstract

LA INVENCION SE REFIERE A UN METODO Y A UN APARATO PARA LA INSPECCION DE LOS COLORES, Y A UN METODO DE CONTROL DE UNA CAMARA DE VIDEO PARA LA ADQUISICION DE UNA IMAGEN DE COLOR BAJO CONDICIONES DE CAPTURA DE IMAGENES VARIABLE. UNA CAMARA DE VIDEO (1) TIENE UNA SALIDA DE ROJO, VERDE Y AZUL (RGB) QUE ESTA PROVISTA DE UNA ABERTURA DE IRIS CONTROLABLE, UNA GANANCIA DE SEÑAL RGB TOTAL CONTROLABLE, GANANCIAS DE CANAL DE SEÑAL DE RGB INDEPENDIENTEMENTE CONTROLABLES Y BALANCE DE CANAL DE SEÑAL RGB CONTROLABLE. LOS PARAMETROS CONTROLABLES SON CONTROLADOS POR UNA UNIDAD DE CONTROL (3) EN LA FORMA DE UN ORDENADOR PERSONAL QUE TIENE UN TABLERO DE CAPTURA DE IMAGENES (4). EL ORDENADOR PERSONAL GENERA SEÑALES DE UNA SEÑAL DE UNA IMAGEN RECIBIDA DESDE LA CAMARA DE VIDEO. LAS SEÑALES SE UTILIZAN PARA CORREGIR LOS PARAMETROS CONTROLABLES PARA MEJORAR EL RENDIMIENTO DE CAPTURA DE LAS IMAGENES DE LA CAMARA. LA INVENCION ENCUENTRA APLICACION EN SISTEMAS DE CONTROL DE CALIDAD, POR EJEMPLO PARA CONTROLAR EL COLOR DE LA PINTURA DE PRODUCTOS EN UNA LINEA DE PRODUCCION.
