Load control system having a visible light sensor

A visible light sensor may be configured to sense environmental characteristics of a space using an image of the space. The visible light sensor may be controlled in one or more modes, including a daylight glare sensor mode, a daylighting sensor mode, a color sensor mode, and/or an occupancy/vacancy sensor mode. In the daylight glare sensor mode, the visible light sensor may be configured to decrease or eliminate glare within a space. In the daylighting sensor mode and the color sensor mode, the visible light sensor may be configured to provide a preferred amount of light and color temperature, respectively, within the space. In the occupancy/vacancy sensor mode, the visible light sensor may be configured to detect an occupancy/vacancy condition within the space and adjust one or more control devices according to the occupation or vacancy of the space. The visible light sensor may be configured to protect the privacy of users within the space via software, a removable module, and/or a special sensor.

Dynamic lighting and sensor adjustment for occupant monitoring
11584295 · 2023-02-21 · ·

Systems and methods to proactively adapt image sensor settings of an occupant monitoring system to accommodate ambient lighting changes are provided. The system may track current ambient light, track the driver, and predict upcoming changing lighting conditions. Sensors are used to predict when the ambient light will change and preemptively adjust to prevent dark or washout images. The sensor adjustment may be timed so that the adjustment is made just in time or concurrently with the change in ambient light conditions. The system may predict when the light on the occupant's face will change and proactively readjust the settings of the sensor to accommodate the changed lighting conditions.
