Image processing apparatus, computer readable medium storing program, and image processing method

摘要

An image processing apparatus includes the following elements. An image receiving unit receives a first image and a second image. A first specified area specifying unit allows a user to specify a first specified area in the first image. A first comparison area setting unit sets a first comparison area in the first image on the basis of the first specified area. A second comparison area setting unit sets a second comparison area in the second image. A geometric difference correction unit corrects a difference in geometric properties between a first comparison image in the first comparison area and a second comparison image in the second comparison area. An image output unit outputs an image in which the second comparison image is superimposed on the first comparison image or a difference image between the first comparison image and the second comparison image.
