PROBLEM TO BE SOLVED: To provide an image processor capable of burying a safe pattern code to an output image by an inexpensive constitution. SOLUTION: The image processor 100 has an image forming device 200 and an image reader 300. The image reader 300 has an original-base glass 302 with a fitted white board as a color reference board and a laser-speckle pattern reading unit 310. In the laser-speckle pattern reading unit 310, the white board 304 is irradiated with laser beams 316, and the image data of a laser-speckle pattern is read from a reflected light 318 reflected from the white board 304. In the image forming device 200, the image data of an original and the image data of the laser-speckle pattern are added, and the output image is output on the basis of the added image data.
