ABSTRACT:
According to an embodiment, a ground process unit performs ground addition to input image data, and a pattern generation unit sets positions of components at plural points on a frequency plane including a main scanning axis and a sub scanning axis and converts the additional information into pattern data in which the positions of the components are a base. A pattern embedding unit embeds the pattern data from the pattern generation unit into a ground area of image data from the ground addition unit. A gradation process unit performs an asynchronous gradation process on the pattern embedding unit and output image data of the pattern embedding unit.
