Abstract

Monochrome multi-color, and full-color documents are automatically discriminated from each other, and character and photograph regions are also determined in an automatic manner, thereby producing appropriate binary image data according to the operation results. An image data transformation apparatus includes a binarizing section for converting image data inputted thereto into binary image data associated with a plurality of different colors, binary image data buffers for temporarily storing therein the binary image data, a decision section for deciding based on the input image data whether the monochrome, color, or multi-color output is to be produced and whether an intermediate-tone or particular color pixel is to be processed, and a binary image data selection/output section for selecting as output therefrom binary image data according to the decision results.
