Abstract

Un dispositivo de detección de semáforo incluye una unidad (11) de captura de imágenes configurada para capturar una imagen de los alrededores de un vehículo y una unidad (12) de detección de semáforo configurada para detectar un semáforo a partir de la imagen. La unidad (12) de detección de semáforo extrae un pixel (51) sincronizado con una luminancia que varía en sincronización con un ciclo de corriente alterna de la energía eléctrica suministrada al semáforo, y establece un rango predeterminado que incluye el pixel (51) sincronizado como un grupo (50) de pixeles. La unidad (12) de detección de semáforo, posteriormente, juzga a partir del pixel (51) sincronizado si o no está presente el semáforo cuando el pixel (51) sincronizado se extrae continuamente a partir del grupo (50) de pixeles durante un periodo de determinación predeterminado.
