Abstract:
1. A method for applying, during a halftoning process, error diffusion among a plurality of pixels of an image, wherein the image comprises (i) a plurality of even lines and (ii) a plurality of odd lines such that each even line of the plurality of even lines is interleaved within corresponding odd lines of the plurality of odd lines, the method comprising: determining whether a first pixel of the plurality of pixels of the image is positioned in (i) an even line of the plurality of even lines of the image, or (ii) an odd line of the plurality of odd lines of the image; in response to the first pixel being positioned in an even line of the plurality of even lines of the image, in response to the first pixel being positioned in an odd line of the plurality of odd lines of the image, wherein determining whether the first pixel of the plurality of pixels of the image is positioned in the even line of the image or the odd line of the image comprises determining that the first pixel of the plurality of pixels of the image is positioned in the even line of the image, and wherein the method further comprises wherein generating the first set of error weights further comprises wherein generating the first set of error weights further comprises wherein the first value of the first set of error weights is generated by modifying the second value of the first set of error weights, wherein the second value of the first set of error weights comprises at least a first error weight and a second error weight, and wherein modifying the second value of the first set of error weights comprises setting the first error weight to zero.
