During electronic film development, an area of conventional photographic film is scanned several times using a single scanning station, and at each subsequent time this scanned area is advanced incrementally along the film with multiple levels of overlap with previous scans. The new image scanned at each new time is aligned to an accumulating image that has been extrapolated to the image at the new time, and then the new image is added to the accumulating image in parametric summations that allow an image to be interpolated to any time free of seams where the scans overlap. The invention further teaches a method of steering the alignment by warping the leading edge of the alignment, and a registration method of aligning multiple images that takes advantage of known fixed alignments between images.

1. A method of monitoring change with time of an image comprising a plurality of pixels possessing densities that are functions of time, comprising the steps of:receiving a first density of a pixel at a first time, accumulating to a first parameter sum a first function of the first density and the first time, accumulating to a second parameter sum a second function of the first density and the first time, receiving a second density of the pixel at a second time, accumulating to the first parameter sum the first function of the second density and the second time; and accumulating to the second parameter sum the second function of the second density and the second time.
