1. A method of providing an image of a scene utilizing imaging optics, the method comprising: receiving radiation from the scene impinging on at least one focal plane; sampling a first spectral band to obtain a first band mean signal level, the first spectral band comprising a first plurality of sub-bands; collecting at least one first band image frame in the first spectral band when the first band mean signal level is at or below a first threshold; collecting at least one first image frame in a first sub-band of the first plurality of sub-bands when the first band mean signal level is above the first threshold; sampling a second sub-band of the first plurality of sub-bands to obtain a second sub-band mean signal level; collecting at least one second sub-band image frame in the second sub-band when the second sub-band mean signal level is at or below a second threshold; and generating an image to be displayed by combining at least two collected frames.
