Abstract
A vehicle headlamp device includes headlamps, which are structured so as to be able to project or irradiate given patterns and given shapes without distortion on a given virtual surface in front of a vehicle from a left headlight and a right headlight, respectively, a camera that captures an image of the area in front of the vehicle, and a state detecting portion configured to detect distortion of the given patterns, which are projected or irradiated on an irradiated surface in front of the vehicle, relative to the given patterns projected or irradiated on the given virtual surface in front of the vehicle, based on the captured image, and also detect a state of the irradiated surface based on the distortion, and a correcting portion configured to correct a relative optical axis deviation between the left headlight and the right headlight.
