IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING METHOD

摘要

An image processing apparatus performs a density adjustment process for generating an image containing a copy-forgery-inhibited pattern image for warning against the use of copy products. To help users to easily adjust the density of a latent image portion and a background portion in the copy-forgery-inhibited pattern image, the image processing apparatus determines a density relationship of the latent image portion and the background portion by performing a plurality of adjustment operations, in combination, different in the amount of adjustment relating to the range of variable density in at least one of the latent image portion and the background portion, and sets, based on the density relationship, the density data of each of the latent image portion and the background portion in the data of the copy-forgery-inhibited pattern image.

主权项

1. An apparatus comprising:
a processor; a memory; a setting unit configured to set an identifying value selected from plural different identifying values by a user; and a causing unit configured to cause a printing unit to print out a copy-forgery-inhibited pattern image corresponding to the set identifying value on first paper, wherein the causing unit causes the printing unit to print out plural different images and the plural different identifying values including the currently set identifying value on second paper, each value corresponding to a different one of the plural different identifying images, such that a user can distinctly recognize an image of the plural different images corresponding to the currently set identifying value on the second paper; wherein each image of the plural different images printed out on the second paper includes a first region and a second region having bigger dots than the first region, and a difference in density of the first and second regions in the each image is different.
