Abstract
A method for determining a level of haze within a field of view of an image sensor adapted for detecting a plurality of color components includes collecting a first image of the field of view at a first point in time, defining regions of the first image as a reference and determining reference intensities for each color component. At least one second image is collected at different points in time and intensities for each color component are determined and compared against the reference intensities. If the intensities of second image differ from the reference intensities by more than a predetermined threshold, all or a portion of the second image is designated as being obscured by haze and requiring correction.
