Abstract
A light distribution control device controls a variable light distribution lamp based on images repeatedly obtained from an imaging device. The light distribution control device controls the variable light distribution lamp to form a light distribution pattern determined by a plurality of items of first light distribution pattern information based on the respective images, the first light distribution pattern information including, when the image includes a predetermined light spot, a light shielding part determined based on the light spot and not including a light shielding part when the image does not include a light spot.
Claims14
A light distribution control device for controlling, based on a plurality of images repeatedly obtained from an imaging device that images an area in front of a vehicle, a variable light distribution lamp for radiating a variable intensity distribution visible light beam to the area in front, comprising:
- a first information generation unit for repeatedly generating an item of first light distribution pattern information based on each image of the plurality of images, the first light distribution pattern information including, when the respective image includes a predetermined light spot, a light shielding part determined based on the light spot and not including a light shielding part when the respective image does not include the light spot;
- a storage unit for repeatedly storing a plurality of the items of first light distribution pattern information based on the plurality of images;
- a pattern determination unit for determining a light distribution pattern that should be formed based on the plurality of the items of first light distribution pattern information stored in the storage unit;
- and
- a lamp control unit for controlling the variable light distribution lamp to form the determined light distribution pattern.
