Apparatus for controlling a brightness of a display of a vehicle includes: an infrared illuminator, configured to emit infrared light in the vehicle; a near infrared (NIR) light sensing unit, configured to capture reflected infrared light; an image data processing unit, configured to analyze the reflected infrared light to generate a feedback; an imaging control unit, configured to adjust, in response to the feedback, one or more of a plurality of properties of the NIR light sensing unit, so that readouts of the NIR light sensing unit are within a first range, wherein the image data processing unit generates a calculated NIR intensity readout under the adjusted properties; a reconstruction unit, configured to reconstruct a human perceived brightness based on the calculated NIR intensity readout; and the display, configured to adjust the brightness. The NIR light sensing unit is a unit of a driver monitoring system (DMS).

Apparatus, system and software for brightness control of vehicle display based on infrared camera

Apparatus for vehicle driver recognition includes: a NIR LED illuminator, configured to emit NIR light in the vehicle; a NIR light sensing unit, configured to capture reflected NIR light; an image controlling and processing unit, configured to coordinate the NIR LED illuminator and the NIR light sensing unit, and analyze the reflected NIR light to generate an image; a face detector, configured to determine that a human face exists in the image, and identify a face region; a face feature extractor, configured to analyze the face region to extract a feature vector representing the face region; a face feature dictionary, configured to store existing feature vectors; a face retrieval system, configured to generate an identification result, indicating whether a similarity between the feature vector and any of the existing feature vectors is greater than a first threshold; and a user interface, configured to display the identification result.
