PROBLEM TO BE SOLVED: To provide a method for image processing and an image output apparatus. SOLUTION: In this image processing method, after input image data i (x, y) is subjected to predetermined addition by an adder 10, modulation data Tmod is added to a predetermined threshold value by a method similar to a regular error diffusion method by a threshold value modulation section 50, then a value Tj + Tmod is obtained. The value Tj + Tmod is compared with data i 2 (x, y) that an error is added to the input image data as a threshold value by a comparator 21. An output o (x, y) is determined to be outputted by an output determining section 22 corresponding to the compared result. |
