Claim 8:
9. 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
further comprising:
a controller: responsive to detecting light conditions decreasing below a first threshold amount when operating in colour mode to swap to monochrome mode for subsequent image acquisition; responsive to detecting light conditions increasing above a second threshold amount when operating in monochrome mode to swap to colour mode for subsequent image acquisition; responsive to detecting light conditions decreasing below a third threshold amount above said first threshold amount when operating in colour mode to increase either exposure time or gain for subsequent image acquisition; and responsive to detecting light conditions increasing above a fourth threshold amount less than said second threshold amount when operating in monochrome mode to decrease either exposure time or gain for subsequent image acquisition,

wherein said second threshold is higher than said first threshold.
