Abstract: A light detecting apparatus which can be arranged even in an optical path of which converting angle is relatively large, and can accurately detect light entering along a predetermined direction in an optical path. The light detecting apparatus (10) for detecting light which enters in a predetermined direction in an optical path has a light splitting element (11) having two optical surfaces (11a, 11b) positioned in the optical path, and a photoelectric detector (12) for photo detecting light which propagates inside the light splitting element and which is guided from a side face (11c) of the light splitting element. The light splitting element further has an incident angle conversion section (13) for converting a part of light which enters one optical face of the light splitting element into light entering the other optical surface at an incident angle greater than or equal to a total reflection angle.

Abstract: An imaging system for use in a vehicle headlamp control system includes an opening, an image sensor, a red lens blocking red complement light between the opening and the image sensor, and a red complement lens blocking red light between the opening and the image sensor. Each lens focuses light onto a different subwindow of the image sensor. The imaging system allows processing and control logic to detect the presence of headlamps on oncoming vehicles and tail lights on vehicles approached from the rear for the purpose of controlling headlamps. A light sampling lens may be used to redirect light rays from an arc spanning above the vehicle to in front of the vehicle into substantially horizontal rays. The light sampling lens is imaged by the image sensor to produce an indication of light intensity at various elevations. The processing and control logic uses the light intensity to determine whether headlamps should be turned on or off. A shutter may be used to protect elements of the imaging system from excessive light exposure.
