Abstract
In accordance with the present invention, there is provided a method for removing the effect of light scattering in a digitized image of a light-scattering film comprising providing a light-scattering correction film that has a uniform optical density; providing a light scattering target film that has a pattern of optical densities; scanning the correction film with a film scanner to create a digital correction film image; scanning the target film with a film scanner to create a digital target film image; measuring the two-dimensional pattern of responses present in the digital correction film image; determining a correction function from the two-dimensional pattern of responses to correct for the effect of light scattering in the digital correction film image; and applying the correction function to the target film image to provide a corrected target film image.
