Patent attributes
A vehicular driver monitoring system includes an illumination source that, when powered, emits light that illuminates at least a portion of a driver of the vehicle. A camera is disposed at the interior of the vehicle and views the portion of the driver. A control includes an image processor that processes captured image data. The illumination source is controlled to modulate intensity of light emitted by the illumination source. The image data output is processed to distinguish a component of the image data output that arises from the illumination source illuminating the portion of the driver from a component of the image data output that arises from ambient light illuminating the portion of the driver. The control filters the image data output to reduce the distinguished component that arises from ambient light and, responsive to processing of the filtered image data output, monitors the portion of the driver.
