<p>An image processing apparatus includes first halftone processing means (14) for generating first halftone image data from input image data using thresholds, first filtering processing means (15) for smoothing the first halftone image data using a first filter having a size corresponding to a cycle of the thresholds, second filtering processing means (16) for smoothing the input image data using a second filter having a characteristic corresponding to the first filter, and evaluating means (17) for evaluating a moiré caused in the first halftone image data based on a difference between the first halftone image data smoothed by the first filtering processing means and the image data smoothed by the second filtering processing means.
