Claim 12
Independent Claim
105 words
A method of manipulating a start serial signal representative of a grayscale image to produce an end serial signal representative of a dilation of the grayscale image, characterised by routing a signal representative of the start serial signal sequentially through one or more processing sequences each having an input signal and an output signal and including the steps of: producing an altered delayed signal from the input signal by delaying the input signal and then adding a constant value to each word in the delayed signal (or vice versa) and logically combining the input signal and the altered delayed signal to produce the output signal.
