Abstract: An illumination source may be coupled to an image capture device through a connector. A light sensor is placed downstream of the connector to measure the light received by the image capture device from the illumination source. The light sensor provides the measurement of the received light to the illumination source for closed-loop control of illumination source. The light sensor may be positioned in a camera housing to take into account light attenuation from the illumination source to the camera. The light sensor may be positioned at other locations on the image capture device. Multiple light sensors may be positioned at different locations on the image capture device to detect sources or locations of attenuation. Redundant light sensors of more than one type of sensor may be used at a single light sensor location to provide for validation of measurements and increase the variety of information measured.
