Abstract:
1. An image processing apparatus comprising: a storage unit that stores an image data of a first image relating to watermark characters including one or more elemental characters; a determination unit that determines whether or not it is difficult to read the watermark characters due to overlap between the watermark characters of the first image and pixels having a pixel value of a second image equal to or more than a predetermined value using the image data of the first image and image data of the 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 watermark characters using the image data of the first image when the determination unit determines that it is difficult to read the watermark characters; and a synthesis unit that generates a synthesis image in which the second image and the third image are overlapped using the image data of the second image and the image data of the third image.
