    摘要： A system includes an illumination source operable at an adjustable duty cycle, a camera arranged to detect illumination from the illumination source, and a computer communicatively coupled to the illumination source and the camera. The duty cycle indicates a proportion of time that the illumination source is illuminated in a repeating pattern. The computer is programmed to operate the illumination source with the duty cycle at a baseline duty cycle in response to failing to detect an object having a preset type in image data from the camera, and operate the illumination source with the duty cycle at a high duty cycle in response to detecting the object having the preset type in the image data from the camera. The high duty cycle has the illumination source illuminated for a greater proportion of time than the baseline duty cycle.

    摘要： A reference value creating device includes processing circuitry configured to; vehicle-related information related to a vehicle; determine a road type of a road on which the vehicle is traveling on a basis of the acquired vehicle-related information; acquire feature amount information regarding a feature amount of an occupant of the vehicle calculated on a basis of a captured image including a range in which at least a face of the occupant of the vehicle is present; and create a reference value of the feature amount for estimating an alertness level of the occupant on a basis of the acquired feature amount information, and create, when the determined road type has changed, the reference value of the feature amount corresponding to the changed road type.
