Patent ID: 7452048

Claim:
A method of reading a two-dimensional code carried on an article in the form of an array of dots that represent image processing instructions, the method including the steps of: (a) scanning the article with a scanner of an image processing device to generate a number of pixels represented by each dot; (b) generating, using the number of pixels, a signal representing a pixel pattern to be communicated to processing circuitry of the image processing device; (c) processing the signal at the processing circuitry to determine an extent of area on the article covered by the two dimensional code; (d) processing a part of the signal representing the determined area to detect a bit pattern represented by the pixel pattern within the determined area; (e) writing the bit pattern as bytes to a data storage means of the image processing device; and (f) processing a resultant byte pattern to decode the image processing instructions represented by the two-dimensional code, the image processing device using the decoded image processing instructions to process an image.
