Abstract:
1. An image processing method implemented by one or more processors, comprising: detecting using said one or more processors an edge width of an edge portion of input image data; determining using said one or more processors a localized conversion ratio based on the edge width and a ratio control amount, wherein the localized conversion ratio is localized to each one of at least three segments of said edge width, wherein said at least three segments include a leading edge segment, a control edge segment and a trailing edge segment, in which the ratio control amount is positive in the leading edge segment, positive in the trailing edge segment and negative in the control edge segment of the edge portion such that the total sum of the leading edge segment, control edge segment and trailing edge segment is zero, the localized conversion ratio being generated by the expression: z=z generating an output image by applying the localized conversion ratio to the input image data to convert a number of pixels in the segment of the edge portion.
