Patent ID: 8660357

Claim:
An image processing apparatus comprising: a storage unit that stores a first image including a stamp character string including one or more elemental characters; a determination unit that determines whether or not the stamp character string is readable using image data of the first image and image data of a second image read by a scanner when the first image and the second image are overlapped; a generation unit that generates a third image obtained by correcting the first image to improve readability of the stamp characters using the image data of the first image when the determination unit determines that the stamp character string is not readable; and a synthesis unit that generates a synthesis image in which the second image and the third image are overlapped; wherein the generation unit shifts the stamp character string of the first image in a parallel manner to generate the third image such that any of two or more continuous characters of the elemental character constituting each stamp character string are not overlapped with a pixel of the second image having a pixel value greater than or equal to a predetermined value when the number of elemental characters is 3 or more.
