Claim:
1. A method comprising: detecting, by a detector unit, a first image parameter of light emitted by a pulsed light source using a first exposure time; detecting, by the detector unit, at least one second image parameter of the light of the light source using at least one second exposure time that is different than the first exposure time, wherein the first image parameter and the at least one second image parameter represent a same spatial location at consecutive times; setting, by processing circuitry, the detector unit to a predetermined value between the detection of the first image parameter and the detection of the at least one second image parameter; evaluating, by the processing circuitry, the at least one second image parameter to detect a pulsed light source when the at least one second image parameter meets a predetermined criterion; and determining the predetermined criterion based on a predetermined value to which the detector unit is reset, wherein the predetermined criterion is met in the evaluating step when the at least one second image parameter coincides with the predetermined value.
