Method and apparatus for detecting a pixel distance to adjust a threshold value

摘要

A method of and apparatus for detecting a pixel distance to adjust a threshold value are disclosed. The method and apparatus include determining a first coordinate of a first pixel with reference to a minor pixel for each pixel of an image, and detecting a first pixel distance which corresponds to a distance between the first pixel and the minor pixel by using the determined first coordinate, wherein the first pixel is binarized by adjusting a threshold value based on the detected first pixel distance, and the first coordinate is reset when the binarized first pixel is determined to be the minor pixel.
