A traffic light detection device is provided with an imaging unit (11) that acquires an image by imaging around a vehicle, and a traffic light detection unit (12) that detects a traffic light from the image. The traffic light detection unit (12) extracts synchronized pixels (51) of which the brightness changes in synchronism with an alternating-current period of electric power supplied to the traffic light, and sets a predetermined range including the synchronized pixels (51) as a pixel group (50). If the synchronized pixels (51) are extracted from the pixel group (50) successively for a predetermined determination period, it is determined from the synchronized pixels (51) whether the traffic light is present. |
