    Abstract: Disclosed are embodiments of methods, systems, and apparatus for providing multiple image fields or regions on an imaging array. In certain preferred embodiments, a high density imaging array may be partitioned into two or more regions, each of which may be used to render a separate view of the scan volume. This arrangement may provide an increase in the effective scan volume beyond the volume available with a single imager having a single point of view and may allow for reading of encoded symbols at a variety of orientations that would otherwise preclude accurate imaging with a single imager.

    Abstract: A method aligns a second image of an object taken at a second time with a first image taken at a first time, wherein the object experiences motion relative to an imager between the first and second times. The images are formed of sets of pixels arranged horizontally and vertically in a pattern. The method operates on the pixels of the second image by performing a series of operations to affect an affine transformation without performing matrix arithmetic, preferably by table look-up. The method shifts the pixels of the second image vertically by a constant vertical offset, shifts the pixels of the second image horizontally by a constant horizontal offset, shears the second image horizontally by a skew factor, shears the second image vertically by a skew factor, scales the second image horizontally by a horizontal scale factor; and scale the second image vertically by a vertical scale factor.
