Abstract:
1. A method of processing, within an imaging system, an input image comprising a plurality of input pixels, the method comprising: for each input pixel of the plurality of input pixels, determining, by the imaging system, an integer offset value with respect to pixel location in an irregular scan path; for each input pixel of the plurality of input pixels, correlating, by the imaging system, a location of the input pixel with a pixel location in the irregular scan path to determine (i) a fractional offset value and (ii) a fractional scan path position; for each input pixel of the plurality of input pixels, calculating, by the imaging system, an adjusted pixel that corresponds to the input pixel based on (i) a value of the input pixel, (ii) the correlated pixel location in the irregular scan path for the input pixel, (iii) the fractional offset value for the correlated pixel location in the irregular scan path, and (iv) values of one or more input pixels near the input pixel; and producing, by the imaging system, an output line by retrieving one or more subsets of sequential adjusted pixels, each subset having adjusted pixels that correspond to a same integer offset value.
