Abstract
A traffic light detecting device includes a camera capturing an image in the travelling direction of a vehicle, and a traffic light detecting unit detecting a traffic light from the image. The unit sets reference signals the number of which is a multiple of three, and phases of which are shifted each other by a time obtained by dividing a cycle of an alternating current power supplied to the traffic light by the multiple of three, and adjusts a phase of the reference signal which is closest to the phase of the alternating current power, to the phase thereof. The unit extracts from the image a synchronized pixel with a luminance which varies in synchronization with the reference signal having the phase adjusted to the phase thereof, and judges that a traffic light is present at a position of the synchronized pixel.
