Claim 3:
4. The vehicle OMS according to claim 1 wherein:
said image sensor comprises an array of sub-pixels which are respectively selectively sensitive to: red and infra-red; blue and infra-red; and green and infra-red light, said device being configured to selectively operate in either: a colour mode where a multi-plane image frame corresponding to the full image sensor is provided, each plane derived from red, green or blue sensitive sub-pixels respectively; or a monochrome mode, where sensor
information from sub-pixels is aggregated to provide a single image plane; and
said controller is: responsive to detecting light conditions decreasing when operating in a first colour mode to swap to a first monochrome mode for a first subsequent image acquisition; responsive to the detecting light conditions increasing
when operating in the first monochrome mode to swap to a second colour mode for a second subsequent image acquisition; responsive to the detecting light conditions decreasing when operating in the second colour mode to increase either exposure time or gain for a third subsequent image acquisition; and responsive to
detecting light conditions increasing when operating in the first monochrome mode to decrease either exposure time or gain for a fourth subsequent image acquisition.
