1. A color mode determination apparatus comprising:
a color mode determining section that obtains image data including a plurality of visualization objects representing visualization targets, performs polychrome/monochrome determination on whether the visualization object is polychromic or monochromic, and performs color mode determination on whether the image data is polychromic image data or monochromic image data based on a result of the polychrome/monochrome determination; and an overlap determining section that determines whether a predetermined visualization object is overlapped with other visualization objects when the polychrome/monochrome determination is performed for the predetermined visualization object, wherein the color mode determining section changes a determination target range of the polychrome/monochrome determination depending on whether the predetermined visualization object is overlapped with other visualization objects, in the color mode determining section, if the overlap determining section determines that the predetermined visualization object is partially overlapped with other visualization objects, a size of a combined region obtained by combining a rectangular region of the predetermined visualization object and a rectangular region of the other visualization objects into a single rectangular region is compared with a value obtained by adding a size of the rectangular region of the predetermined visualization object and a size of the rectangular region of the other visualization objects by considering them as individual rectangular regions, the combined region is determined as a determination target range of the polychrome/monochrome determination when the size of the combined region is smaller than the value obtained by the addition, and each of the individual rectangular regions is determined as the determination target range of the polychrome/monochrome determination when the value obtained by the addition is smaller than the size of the combined region. |
