    Abstract: A single pass scanner having a trilinear array, a source of white light, filters of the three primary colors and a separate source of infrared light is used in various methods of removing medium-based defects from a scanned film image. The method generates an infrared channel in addition to the common visible channels by covering the parallel rows of sensors in the trilinear array respectively with a red, green and blue filter to create the three color channels. Normally, each of the three color filters also passes infrared light, which is removed by filters external to the sensors. In a specific embodiment, interstitial in time between two visible light scans, the sensor is exposed to infrared light for a single scan. As the trilinear array sweeps across an image in time and spatial synchronization with the exposing lights, at least two visible channels and an infrared channel are generated.

    Abstract: One aspect of the invention is a method for altering defects in a digital image. At least a first pixel of a first channel of a digital image is filtered using digital circuitry to produce a filtered pixel by averaging the intensity of the first pixel and a plurality of additional pixels in the neighborhood of the first pixel. At least one of the pixels is weighted in response to the intensity value of at least one pixel in a defect channel associated with the digital image. A corrected digital image is produced using the digital circuitry in response to the filtered pixel and the first channel of the digital image.
