1. A headlight control device that controls a light distribution pattern of a headlight, comprising:
a processor;
a storage device; and
a headlight control program and an image recognition program that are stored in the storage device and executed by the processor, wherein
the headlight control program includes a sequence control section that generates a headlight control signal from an image captured by a camera mounted on a vehicle, and a control value calculation section that calculates a control value for the light distribution pattern in the headlight control signal,
the image recognition program includes a license plate recognition section that detects a license plate of a preceding vehicle from the image, and a cut-off line recognition section that detects a cut-off line of the headlight from the image, and
the control value calculation section calculates the control value for the light distribution pattern such that the cut-off line detected by the cut-off line recognition section is positioned higher by a predetermined height than an upper end of the license plate detected by the license plate recognition section.
