<p><P>PROBLEM TO BE SOLVED: To provide an image processing apparatus for suppressing noise and level difference in gradation that is easily generated in the gradation region while restricting the generation of periodical pattern and roughness of image. <P>SOLUTION: An image accepting device of the image processing apparatus accepts images, a matrix generating device generates a matrix based on a function of assuring the minimum value in the geometrically isotropic and uniform point dispersion, and a noise adding device adds noise to the image accepted with the image accepting device by a periodical mask process using the matrix generated with the matrix generating device. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
