Abstract
An image processing apparatus receiving a pixel value of a multivalue image includes: an input noise generating section that generates a noise; a green noise generating section that generates a green noise from an output value of a binarized processed pixel; an adder section that adds an error integrated value, the green noise and the noise, to the pixel value of the target pixel; the threshold value processing section that binarizes the pixel value of the target pixel after adding the error integrated value, the green noise and the noise; a subtractor section that calculates an error value by calculating a difference between an output value of the binarized target pixel and the pixel value of the target pixel including the error integrated value and the noise; and an error integrating section that outputs the error integrated value by using the error value of the binarized processed pixel.
