Claim One:
1. An image processing device comprising: a first storing unit that stores therein an inner-region pattern that is applied to an inner region of an image to be processed; a second storing unit that stores therein an outer-region pattern that is applied to an outer region of the image; a third storing unit that stores therein a mask pattern; a dividing unit that divides the image into a plurality of regions; a first generating unit that generates an inner-region image by performing first image processing on the inner region in each of the regions with the inner-region pattern; a second generating unit that generates an outer-region image by masking the outer-region pattern with the mask pattern to obtain a masked outer-region pattern, and performing second image processing on the outer region in each of the regions with the masked outer-region pattern; and a third generating unit that generates a watermark image based on the inner-region image and the outer-region image.
