Abstract
A system and method for reading a machine readable code associated with an object moving relative to an imaging device may include capturing a first image of the machine readable code at a first resolution. A second image of the machine-readable code with a non-integer pixel shift in alignment at the first resolution may be captured. An interleaved image may be formed from the first and second images. An image of the machine-readable code may be generated at a second resolution using the interleaved image, where the second resolution is higher than the first resolution.
