Abstract
An image-forming apparatus processes image signals based on a predetermined gradation-converting curve. The predetermined gradation-converting curve includes at least one of: a first gradation in which a maximum absolute-value of a difference between a lightness gradation curve and its smoothed curve in a range of about 1/10 of its gradation number is not greater than 1; a second gradation in which a maximum absolute-value of first-order differential values of a difference curve between a lightness gradation curve and its smoothed curve in a range of about 1/10 of its gradation number is not greater than 100; and a third gradation, in which a maximum absolute-value of first-order differential values of a difference curve between a first smoothed curve in a range of about 1/100 of a gradation number and a second smoothed curve in a range of about 1/10 of a gradation number, is not greater than 100.
