Abstract:
1. A method of reading and decoding scrambled and encoded two-dimensional data represented on a sheet of media as a dot matrix, the method comprising the steps of; detecting a data area on the sheet of media by detecting targets on the sheet of media, the step of detecting the data area detecting as many targets as possible, each target in the form of a black square and a white dot, and determining whether a predetermined number of the white dots define a single logical straight line, the step of detecting the data area further then determining a start of the data area a predetermined distance from the straight line; detecting a bit pattern represented by the dot matrix and writing the bit pattern to generate a byte pattern; descrambling the byte pattern to generate coded data; decoding the data to obtain an instruction script; and operating a central processor to manipulate an image according to the instruction script.
