Abstract:
1. An image processing apparatus for outputting print image data to a printing unit which prints an image by applying a printing material to a printing medium, comprising: a color information holding unit which holds items of color information C a latent image input unit which inputs infrared light ray latent image data of M tones under infrared light (N≧M≧3); and an output unit which decides one color information item Ci (1≦i≦N) held by said color information holding unit according to a value of a pixel of interest of the input infrared light ray latent image data, and outputs, to the printing unit, the decided color information item Ci as pixel values of print image data corresponding to the pixel of interest, wherein, assuming that {C said output unit decides a value L required to specify an infrared light ray absorption rate according to a value of the pixel of interest of the input infrared light ray latent image data, generates a random number value r falling within a range from 1 to q using a predetermined random number generating unit, and outputs color information C
