Abstract
A vehicular lamp system includes: an imager; a luminance analyzer that detects a luminance of each of multiple individual regions; an illuminance setting unit that determines an illuminance value of light emitted to each individual region, based on a detection result from the luminance analyzer; a light source unit; and a light source controller that controls the light source unit. The illuminance setting unit uses different functions to determine the illuminance value for an individual region that falls within a certain first luminance range, and the illuminance value for an individual region that falls within a certain second luminance range.
Claims9
A vehicular lamp system, comprising:
- an imager that captures an image of an area in front of the subject vehicle;
- a luminance analyzer that detects a luminance of each of a plurality of individual regions arranged in front of the subject vehicle, on the basis of information acquired from the imager;
- an illuminance setting unit that determines an illuminance value of light emitted to each individual region, on the basis of a detection result from the luminance analyzer;
- a light source unit that independently controls the illuminance of light emitted to each of the plurality of individual regions;
- and
- a light source controller that controls the light source unit on the basis of an illuminance value determined at the illuminance setting unit, wherein
- the illuminance setting unit uses different functions to determine the illuminance value for an individual region that falls within a predetermined first luminance range, and the illuminance value for an individual region that falls within a predetermined second luminance range.
A control device for a vehicular lamp, the control device comprising:
- a luminance analyzer that detects a luminance of each of a plurality of individual regions arranged in front of the subject vehicle, on the basis of information acquired from an imager that captures an image of an area in front of the subject vehicle;
- an illuminance setting unit that determines an illuminance value of light emitted to each individual region, on the basis of a detection result from the luminance analyzer;
- and
- a light source controller that controls a light source unit that independently controls the illuminance of light emitted to each individual region, on the basis of an illuminance value determined at the illuminance setting unit, wherein
- the illuminance setting unit uses different functions to determine the illuminance value for an individual region of which the luminance is included in a predetermined first range, and the illuminance value for an individual region of which the luminance is included in a predetermined second range.
A control method for a vehicular lamp, the control method comprising:
- detecting a luminance of each of a plurality of individual regions arranged in front of the subject vehicle, on the basis of information acquired from an imager that captures an image of an area in front of the subject vehicle;
- determining an illuminance value of light emitted to each individual region, on the basis of a detected luminance;
- and
- controlling a light source unit that independently controls the illuminance of light emitted to each individual region, on the basis of a determined illuminance value, wherein,
- in the determining an illuminance value, different functions are used to determine the illuminance value for an individual region of which the luminance is included in a predetermined first range, and the illuminance value for an individual region of which the luminance is included in a predetermined second range.
