A traffic light detection device uses an image pickup unit mounted on a vehicle to extract, from an image taken of surroundings of the vehicle, synchronized pixels (DA1 to DA3), whose brightness changes in synchronization with an alternating current period of electric power supplied to a traffic light, and detects the traffic light from the synchronized pixels. The traffic light detection device is provided with: a positional variation calculation unit that calculates positional variation amounts (G1 to G3, g1 to g3) of continuously extracted positions of the synchronized pixels; and a signal lamp determination unit that determines, as a signal lamp candidate, the synchronized pixels whose positional variation amount is equal to or smaller than a threshold value.
