Claim One:
1. A method for determining a level of haze within a field of view of an image sensor adapted for detecting one or more color components, the method comprising: (a) collecting a first image of one or more objects within the field of view at a first point in time at which a first set of haze conditions are present; (b) defining one or more regions of the first image as a reference; (c) determining reference intensities for each of the one or more color components for the reference; (d) collecting at least one second image of one or more objects within the field of view at one or more second points in time at which a different second set of haze conditions are present; (e) determining intensities for each of the one or more color components within the at least one second image; (f) comparing the intensities for each of the one or more color components of the at least one second image against the reference intensities; (g) if the intensities of the at least one second image differs from the reference intensity by more than a predetermined threshold, designating all or a portion of the at least one second image as being obscured by haze; and (h) generating an output identifying the designated portions of the at least second image as requiring correction.
