Abstract: A light distribution control apparatus controls formation of a light distribution pattern by a variable light distribution lamp by using an image based on an imaging apparatus that images an area in front of a vehicle. When changing an illuminance in a first illuminance region equal to or below a predetermined first illuminance threshold value, the light distribution control apparatus changes the illuminance by a first amount of change smaller than an amount of change for changing the illuminance in an illuminance region above the first illuminance threshold value.

Abstract: A lamp system includes: an imaging apparatus; a variable light distribution lamp; a first bracket that supports the imaging apparatus; a second bracket that supports the variable light distribution lamp such that an irradiation direction is variable and that is independently displaceable with respect to the first bracket; an irradiation direction sensor; and a light distribution control apparatus that detects an object, defines a position of a shielded-light portion based on a mutual correspondence between an imaging direction and an irradiation direction, and controls the variable light distribution lamp to form the light distribution pattern having the shielded-light portion. The light distribution control apparatus defines, when the irradiation direction is changed, the shielded-light portion at a position shifted from the position of the shielded-light portion defined based on a pre-change correspondence by an amount determined by the amount of change.

Abstract: A light distribution controlling device generates a processed image by adding a pixel line of a luminance value higher than a predetermined threshold to an end, in a width direction of a vehicle, of an image that is based on a first imaging device; extracts, from the processed image, a processing region that includes a front vehicle; generates an extracted image by subjecting the processing region to an extracting process of extracting a high-luminance pixel with use of the threshold; and sets a shaded portion to overlap the front vehicle based on a pair of high-luminance pixels included in the extracted image and determines a light distribution pattern that includes the shaded portion.

Abstract: A vehicle detection device performs detection of a vehicle in front within a processing region set in an image based on an imaging device and displaces or transforms the processing region based on a change in shape of a road in front.

Abstract: An attitude determining device outputs a notification signal if, in an image that an imaging device has captured of a predetermined attitude determining pattern formed by a light distribution variable lamp that illuminates a region ahead of a vehicle with light, a position of the attitude determining pattern in a direction about an optical axis of the imaging device deviates from a normal position by no less than a predetermined amount.

Abstract: A light distribution controlling device controls a low beam lamp capable of forming a low beam light distribution pattern having a cutoff line. The light distribution controlling device controls the low beam lamp so as to keep a region above a reference formation region for the low beam light distribution pattern from being illuminated with light, in accordance with a change in an angle of tilt of a vehicle's right-left axis of a vehicle provided with the low beam lamp.

Abstract: A high-definition lamp unit has a plurality of individually controllable pixels, and illuminates a road face with beam with a light distribution pattern corresponding to states of the pixels. The sensor is provided to enable detection of a pitch angle of a vehicle body. A controller controls on/off of the pixels according to the pattern to be drawn on the road face, and corrects the states of the pixels PIX according to the pitch angle.

Abstract: A light distribution control device controls, using an image based on an imaging device for imaging an area in front of a vehicle, a variable light distribution lamp capable of irradiating the area in front with a variable intensity distribution visible light beam. The light distribution control device defines a light irradiating the area in front corresponding to a predetermined high-brightness pixel included in the image to be a subject light, adjusts an illuminance of the subject light so that a brightness value presented by the high-brightness pixel gradually approaches a predetermined target low brightness, and, during adjustment, varies the illuminance by a smaller amount of change when increasing the illuminance than when decreasing the illuminance.
