Claim 9:
10. The vehicle OMS according to claim 6 wherein:
each pixel of said image sensor comprises pixels which are sensitive to at least infra-red light, and
said controller when operating in ROI mode is: responsive to detecting lighting conditions decreasing, for increasing the exposure time for a subsequently acquired image, unless said exposure time exceeds a threshold time for illuminating the rows of said ROI with a single pulse of IR light from said IR light source; responsive to said exposure time exceeding the threshold time, for increasing an intensity of said at least one IR light source, unless said increased intensity would exceed a maximum intensity; and responsive to said increased intensity exceeding a maximum intensity, for increasing a gain for pixels of said image sensor.
