Abstract
An illumination control device includes: an accident detection unit to detect an accident of a vehicle using a signal output from a sensor mounted on the vehicle; a lamp body control unit to command a lamp body that illuminates a vehicle interior using visible light to turn on when an accident is detected by the accident detection unit; and a lamp color changing unit to change a lamp color of the lamp body when the accident is detected by the accident detection unit.
Claims9
An illumination control device comprising:
- processing circuitry configured to
- detect an accident of a vehicle using a signal output from a sensor mounted on the vehicle;
- command a lamp body that illuminates a vehicle interior using visible light to turn on when an accident is detected;
- change a lamp color of the lamp body when the accident is detected;
- command an imaging device that performs imaging using visible light to image a vehicle interior when the accident is detected;
- specify a position of a site of a living body in the vehicle interior using an imaged image acquired in response to the command;
- and
- estimate the position of the site of the living body in the vehicle interior and command the lamp body to adjust light distribution with respect to the estimated position of the site of the living body when the position of the site of the living body in the vehicle interior is not specified.

An illumination control device comprising:
- processing circuitry configured to
- detect an accident of a vehicle using a signal output from a sensor mounted on the vehicle;
- command a lamp body that illuminates a vehicle interior using visible light to turn on when an accident is detected;
- and
- change a lamp color of the lamp body when the accident is detected;
- select a type of biometric information to be acquired by referring to type information indicating types of biometric information stored in advance when the accident is detected;
- adjust the lamp color of the lamp body depending on the type of biometric information having been selected;
- and
- specify a color of external light incident on the vehicle interior using the imaged image acquired by the imaging device and lamp color information indicating a lamp color of the lamp body;
- and
- perform adjustment in such a manner that the lamp color of the lamp body turns into a color obtained by subtracting the color of the external light from the color indicated by the lamp color information when the type of biometric information having been selected is a bleeding state or a complexion.
