Abstract

Un equipo de reconocimiento de código de reconocimiento óptico parareconocer un código de reconocimiento óptico, donde el código de reconocimientoóptico se construye por una secuencia de un predeterminado número de celdas, dondeuno de una pluralidad de colores se asigna a cada celda y el mismo color no se asigna aceldas vecinas, el equipo comprende medios divisores para dividir los datos de imagen obtenidos por imágenes de uncódigo de reconocimiento óptico en áreas de color basadas en parámetros indicativos decolores; medios de determinación para determinar si cada una de las áreas de colordivididas es una celda como un componente del código de reconocimiento óptico o nocaracterizado en que los medios divisores se adaptan para dividir los datos de imagen en un área deuno o más colores que forman un patrón de marcado y un área de un color indicativo dezona tranquila, y el color indicativo de la zona tranquila es un color de espacio distinto de loscolores que forman el patrón de marcado, y los medios de determinación se adaptan para determinar que un área objetivo escandidata a celda como componente de un código de reconocimiento óptico, cuando elárea objetivo satisface cualquiera de las siguientes condiciones.
