A traffic light detecting device includes an image capturing unit (11) configured to capture an image of surroundings of a vehicle and a traffic light detecting unit (12) configured to detect a traffic light from the image. The traffic light detecting unit (12) extracts a synchronized pixel (51) with a luminance which varies in synchronization with an alternating current cycle of electric power supplied to the traffic light, and sets a predetermined range including the synchronized pixel (51) as a pixel group (50). The traffic light detecting unit (12), then, judges from the synchronized pixel (51) whether or not the traffic light is present when the synchronized pixel (51) is continuously extracted from the pixel group (50) for a predetermined determination period.
