A signal processing device includes a first acquisition section that acquires first illuminance information indicating illuminance of an inside of a moving body, a second acquisition section that acquires second illuminance information indicating illuminance to be compared with the first illuminance information, and a light adjusting control section that controls a light adjustment by a device included in the moving body on a basis of a result of a comparison between illuminance of the first illuminance information and illuminance of the second illuminance information.

An apparatus for controlling an in-vehicle lighting environment includes: a passenger state determination unit that determines a state of a passenger using a gaze of the passenger photographed by a camera of a vehicle; a driving state determination unit that determines a driving state of the vehicle using an acceleration value measured by an acceleration sensor of the vehicle; an external environment state determination unit that determines an external environment state of the vehicle using an external illuminance value measured by an external illuminance sensor of the vehicle; and a lighting environment control unit that controls an illuminance and a color of a first light disposed inside the vehicle based on data determined by at least one determination unit among the passenger state, driving state, and external environment state determination units.

A getting-off support device of a vehicle continues to issue an alarm for a predetermined time when a physical body condition indicating that a physical body that obstructs getting-off of an occupant in the vehicle exists around the vehicle and a getting-off condition indicating that the occupant in the vehicle intends to get off the vehicle are satisfied, and prolongs the time of issuing the alarm when both of the physical body condition and the getting-off condition are further satisfied while the issuing of the alarm is continued.

A vehicle warning light monitoring assembly includes a monitoring circuit that is integrated into an electrical system of a vehicle. The monitoring circuit is in electrical communication with each of a plurality of exterior lights on the vehicle. A display is integrated into a dashboard of the vehicle to display the name of one of the exterior lights on the vehicle that has malfunctioned. A communication unit is pluggable into a data port in a vehicle to receive operational data pertaining to the exterior lights of the vehicle. The communication unit displays exactly which exterior light on the vehicle has malfunctioned. Additionally, the communication unit is wireless communication with a personal electronic device for communicating the operational data to the personal electronic device.

A system is provided for illuminating the face of an occupant for a video call in a car. At least one light source has a main light emission direction (A) which is directed toward the face of the occupant. The system also includes a camera provided to record the face of the occupant. The system controls the light source in such a way to obtain a flickering free recording of the face of the occupant.

A method for preventing a collision between a motor vehicle and at least one target object, the motor vehicle includes a detection system capable of detecting the target object and a warning system including at least one light module. The method includes detecting the target object and determining a position and a speed of the target object using the detection system. The method further includes estimating a critical trajectory likely to be followed by the target object in order to collide with the vehicle depending on the position and the speed of the target object, the critical trajectory being associated with a collision risk/collision time relationship. The method additional includes transmitting at least one light warning to the driver of the vehicle using the light module of the warning system.
