Method for determining ambient light level with respect to exposure control device of camera mounted in e.g. passenger car, involves evaluating control information of exposure control device, to determine ambient brightness value

摘要

The method (200) involves obtaining (210) the control information comprising variable of state of exposure control device (104) for controlling a vehicle camera (102). The control information is evaluated (220) to determine the ambient brightness value. The determined ambient brightness value is output to lighting control unit (106) of vehicle (100), for controlling the interior and exterior lights of vehicle. Independent claims are included for the following: (1) a device for determining ambient light level with respect to exposure control device of vehicle camera; (2) a method for controlling interior and exterior lights of vehicle; (3) a device for controlling interior and exterior lights of vehicle; (4) a computer program for determining ambient light level with respect to exposure control device of vehicle camera; and (5) a computer program for controlling interior and exterior lights of vehicle.
