Abstract
Image stitching from multiple line scanners may be provided by selecting, at a plurality of times while progressing a film roll from a supply reel to a take-up reel, overlap areas on the film roll between first and second field of views of a first and second line scan sensors that read first and second data streams from the film roll; calculating, at each time, a difference measure between the first and second data streams in a current overlap area for a current time; adjusting, based on the difference measure, a size or a position of the overlap area for use at a subsequent time as the film roll progresses such that the current overlap area has a first number of pixels and a subsequent overlap area has a second number of pixels; and blending the first and second data streams at the current time at the current overlap area.
