1. An image processing apparatus comprising: a restrictive condition storage unit in which at least one restrictive condition, which is to be applied to an image to be output and is acquired from a subject, is stored; an accepting unit that accepts an image that is obtained by shooting the subject and has at least one field; an image changing unit that applies the at least one restrictive condition to the at least one field of the image accepted by the accepting unit, changes the at least one field so that the at least one field satisfies the at least one restrictive condition, and acquires at least one new field; and an image output unit that outputs the at least one field acquired by the image changing unit.
