Abstract
Some embodiments are directed to an imaging that includes an image sensor; a tunable filter; and a controller operatively connected to the tunable filter and to the image sensor. The imaging system is configured to: tune the tunable filter to a plurality of filter states. The image sensor acquires, at each state of the plurality of states, an image of an object, to provide different images of the object. The controller calculates a state related score, for each state that is indicative of one or more properties of at least one subset of pixels of the at least one image acquired at the state, to provide a plurality of state related scores; and determines, based on at least one of the plurality of state related scores, a desired state of the tunable filter that satisfies a desired state related score criterion; and sets the tunable filter.
