1. A vehicle light source detection device mounted to an own vehicle configured to detect a light source of a vehicle in captured image data, comprising:

  • a light source appearance detection section configured to detect a presence of a light source detected in captured image data;

    a gradient calculation section configured to calculate a gradient of a road on which the own vehicle is running;

    a vanishing point estimation section configured to estimate a vanishing point in the captured image data on the basis of at least the detected gradient of the road;

    a reliability value calculation section configured to more increase a magnitude of a reliability value of the detected light source when a position of the detected light source more approaches to the vanishing point in the captured image data, and the reliability value of the detected light source indicating a possibility that the detected light source is a light source of a vehicle; and

    a light source detection section configured to determine that the detected light source is a light source of a vehicle when the reliability value of the detected light source is not less than a predetermined reference value.
