    • PROBLEM TO BE SOLVED: To provide an error prediction method (error diffusion method) capable of solving the problem of calculating the output value when the error of the pixel is unknown.
      SOLUTION: In the error diffusion method applied to halftone processing for image data, the image data comprise a plurality of pixels. The method comprises the steps of: dividing the image data into a plurality of image blocks; selecting one of the pixels belonging to each of the image blocks as a target pixel, wherein the target pixel is located on the boundary of the corresponding image block; assigning a predicted error to the target pixel; and executing the error diffusion method on the rest of the pixels of the image blocks according to the predicted error of the target pixels of the image blocks. When executing the error diffusion, the target pixel is found out within the image block, the predicted error is then assigned to the target pixel, and the output values thereof are calculated.
