Abstract
Un dispositivo de detección de semáforo utiliza una unidad de captación de imágenes montada en un vehículo para extraer, a partir de una imagen tomada de los alrededores del vehículo, pixeles (DA1 a DA3) sincronizados, cuyo brillo cambia en sincronización con un periodo de corriente alterna de la energía eléctrica suministrada a un semáforo, y detecta el semáforo a partir de los pixeles sincronizados. El dispositivo de detección de semáforo se provee con: una unidad de cálculo de variación posicional que calcula las cantidades (G1 a G3, g1 a g3) de variación posicional de las posiciones continuamente extraídas de los pixeles sincronizados; y una unidad de determinación de lámpara de señalización que determina, como un candidato de lámpara de señalización, los pixeles sincronizados cuya cantidad de variación posicional es igual a o menor que un valor de umbral.
