Abstract
A vehicle lamp system includes: a vehicle lamp that emits light to a front area of a vehicle thereby forming a predetermined light distribution pattern; an imaging device that captures an image of the front area of the vehicle; and a foreign substance determination device including a storage unit that stores a light distribution pattern formed in the front area by the vehicle lamp in a state where no foreign substance adheres to a light emitting surface as a reference pattern, and a determination unit that compares a light distribution pattern captured by the imaging device with the reference pattern and determines whether a foreign substance adheres to the light emitting surface based on a determination result.
