Claim One:
1. An image processing device comprising: an original reception unit that receives an original image; a dot image generation unit that generates, on the basis of additive information to be added to the original image, a dot image in which a plurality of dots each formed by one or more pixels are arranged; a determination unit that determines, from a relationship between a position on the dot image and a corresponding position on the original image, whether or not the dots in the dot image can be extracted, on the basis of the original image received by the original reception unit and the dot image generated by the dot image generation unit; a state alteration unit that, when the determination unit determines that any of the dots in the dot image cannot be extracted, alters a state of the non-extractable dot in the dot image; and a composite image generation unit that generates a composite image by superimposing, on the original image, the dot image having the state of the non-extractable dot altered by the state alteration unit, wherein the determination by the determination unit is executed before the composite image generated by the composite image generation unit is printed on a recording medium, the dot image generated by the dot image generation unit has a plurality of dots arranged in a line, the plurality of dots each being formed by one or more pixels, the state alteration unit displaces, in a substantially parallel direction, positions of the plurality of dots aligned on the line, and the plurality of dots being displaced includes dots that are determined to be extractable by the determination unit.
