Abstract: PURPOSE: A method for processing error diffusion is provided to obtain a vertical pattern without generating a diagonal pattern. CONSTITUTION: The kind of dots to be processed is predicted according to a gradation value of an input pixel(S310). The pixel having the same kind of dot placed nearest to the input pixel is searched according to the predicted result. The distance between the input pixel and the pixel located nearest to the input pixel is measured, and the first threshold control value is calculated according to a difference between the distance between the two pixels and an appropriate distance based on a predetermined gradation value(S320). Noise array is applied to an input image to calculate the second threshold control value according to a noise value of the input pixel(S330). A threshold for determining a binary value of the input pixel is adjusted in consideration of the first and second threshold control values(S350). The gradation value of the input pixel is compared with the threshold to determine the binary value of the input pixel(S360,S370). An error value between the gradation value of the input pixel and the binary value is delivered to pixels surrounding the input pixel according to an error diffusion coefficient to correct a gradation value of the surrounding pixels(S400).
