Image processing apparatus, image processing method, and program

Abstract

An image processing apparatus of the present invention compares a first proof image and a second proof image, to detect a different portion, and displays the different portion on a display part. Therefore, an operator can check the second proof image after subjected to an automatic trap processing in respect to only the different portion between the first proof image and the second proof image, and perform a trap edit processing as needed. Hence, the trap edit processing to the second proof image can be performed efficiently, and the operator's workload can be reduced.
