First Claim
1. A method of providing an image of a scene utilizing imaging optics, wherein radiation from the scene impinges on at least one focal plane, the method comprising:
- 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 to increase spatial resolution in the at least one region of interest, the at least one region of interest being illuminated in accordance with the mean signal level and one or more of an illuminator power and an illuminator agility;
collecting at least one illuminated image frame in at least a second spectral band; and
generating at least one image to be displayed from at least the at least one illuminated image frame.
