1. A method for forming a decodable composite image of an optical code that experiences motion, the method comprising: forming a first image of at least a first portion of the optical code at a first time; forming a second image of at least a second portion of the optical code at a second time, whereby the optical code may undergo relative motion between the first time and the second time; determining one or more of the following parameters of an affine transformation relating the second image to the first image: vertical offset, horizontal offset, horizontal skew factor, vertical skew factor, horizontal scale factor, and vertical scale factor; aligning one of the first and second images to the other of the first and second images by utilizing the determined parameters to implement the affine transformation, thereby forming an aligned image; and combining elements of the aligned image and the other of the first and second images to form the decodable composite image of the optical code.
