Abstract

A pattern producing unit performs arithmetic on values of pixels corresponding to a pattern and a basic pattern read from a data storing unit with an AND operation unit, and thereby produces a pattern having substantially the same shade level as the pattern. The latent-image-containing image producing unit produces the latent-image-containing image by selectively combining the pattern and the produced pattern according to the values of respective pixels of mask image data read from the data storing unit for producing a latent image.
