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.

Vehicle headlamp device

An illumination system includes: a light irradiation unit that projects light toward a predetermined illumination area; an image acquisition unit that acquires an image of the illumination area; an object detecting unit that detects a shading object based on image information of the illumination area, acquired by the image acquisition unit; an information generating unit that generates the control information for setting each of the plurality of reflecting mirrors to an on state or an off state such that a plurality of irradiation patterns are alternately irradiated, each of the plurality of irradiation patterns having different arrangement of the dark pixels and the light pixels from each other; and an irradiation control unit that controls the light irradiation unit based on the generated control information.

Illumination system for generating a boundary between a shaded area and an irradiated area

An irradiation system includes: a light position detection unit that detects a light position of an oncoming vehicle from a captured image; a driver position calculation unit that calculates a position upward and shifted in a first direction by a first distance from the light position detected by the light position detection unit, as a driver position; a shaded area generation unit that generates a first area having vertices respectively set at the light position, the driver position and a position shifted in a second direction, opposite to the first direction, by a distance between a pair of lights in the predetermined vehicle from the driver position, as a shaded area; and an irradiation unit that irradiates an area ahead of the host vehicle while shading the shaded area generated by the shaded area generation unit.

Irradiation system that controls headlamps of a vehicle

A projection system includes: a position detecting section that detects the position of a target object located in front of a host vehicle; and a control section which, on the basis of the position of the target object detected by the position detecting section, controls a headlamp so as to project onto the position of the target object a projection pattern that moves in a direction corresponding to the direction of motion of a background at the position of the target object or a direction corresponding to the opposite direction of the direction of motion of the background.

Projection system and computer-readable storage medium

An eye detecting device includes an image generating device for generating a face image, a nostril detecting portion for detecting a nostril in the face image, an eye searching area setting portion for setting an eye searching area in the face image based on a position of the nostril detected by the nostril detecting portion, and an eye searching portion for searching an eye within the eye searching area set by the eye searching area setting portion.
