An imaging system comprising:

• at least one focal plane for providing images of a scene;
• a spectral selector for transmitting a first spectral band, a second spectral band or portions thereof to the at least one focal plane;
• at least one illuminator for illuminating at least one region of interest of the scene;
• a cueing controller for sampling a first spectral band to obtain an initial image frame, determining at least one region of interest of the scene from the initial image frame, each of the at least one region of interest associated with a mean signal level, illuminating the at least one region of interest with at least one illuminator when the mean signal level of the at least one region of interest is at or below a respective threshold of a first plurality of thresholds, the at least one region of interest being illuminated in accordance with a power threshold indicating a minimum illuminator power and agility necessary to illuminate the at least one region of interest, collecting at least one illuminated image frame in at least a second spectral band;
• and
• a data combiner for generating at least one image to be displayed from at least the at least one illuminated image frame.
