摘要
using a continuous-tone input pixel value of a method for generating a binary image is disclosed. Method according to the present invention includes the steps of calculating an input pixel value (i (m, n)) and the optimal distance between the decimal pixel ( (m, n)); Minimum distance between the input pixel and a small number of input pixels using the location information of the minimum distance from the decimal pixel from the pixel (dmin (m, n)) for calculating the phase; Optimal distance ( (m, n)) and minimum distance (dmin (m, n)) calculating a threshold value (t (m, n)) using the; Binary pixel values of the input pixel by using a threshold value (t (m, n)) and the input pixel value (i (m, n)) (b (m, n)) the binary pixel value determining step of determining; Includes; and storing the input pixel and position information of a few pixels in the minimum distance. To generate a binary image having a small number of pixels than a uniform distribution with a small operation by controlling the threshold value of the input pixel by using the location information of the decimal pixel found by the search area in the best error diffusion method by the present invention there.
