Abstract

Un dispositivo de detección de semáforo incluye una unidad (11) de captura de imágenes configurada para capturar una imagen en la dirección de desplazamiento 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 establece señales (L01 a L03) de referencia cuyo número es un múltiplo de tres, y cuyas fases están desplazadas entre sí por un tiempo obtenido dividiendo un ciclo de una energía de corriente alterna suministrada al semáforo por el múltiplo de tres, y ajusta una fase de la señal (L01) de referencia que es más cercana a la fase de la energía de corriente alterna, a la fase de la energía de corriente alterna. La unidad (12) de detección de semáforo extrae a partir de la imagen un pixel (53b) sincronizado con una luminancia que varía en sincronización con la señal (L01) de referencia que tiene la fase ajustada a la fase de la energía de corriente alterna, y juzga que un semáforo está presente en una posición del pixel sincronizado.
