IMAGE FORMING APPARATUS

摘要

An image forming apparatus includes a reading unit that reads image data, a drawing data storage unit that stores object data comprising the read image data so as to allow the stored object data to be distinguished between a vector object and a raster object, a vector gray determination unit that determines whether each of stored vector objects is formed of an achromatic color, a raster gray determination unit that determines whether each of stored raster objects is formed of an achromatic color, and an output data creation unit that converts the stored object data into multicolor when the stored object data includes a chromatic color and converts the stored object data into monochrome when the stored object data is formed only of achromatic colors.

1. An image forming apparatus, comprising:
a data reading unit that reads image data; a band split unit that divides the read image data into a plurality of bands allowing each of object data comprising the image data to be distinguished between a vector object and a raster object; an overlap band detection unit that identifies a band having an overlap between the vector object and the raster object; a specified color value acquisition unit that determines a color value of a vector object existing in the overlap band; an overlap band representative color detection unit that determines a representative color of a raster object existing in the overlap band; an output color value calculation unit that calculates an output color value corresponding to the color value of the vector object and an output color value corresponding to the representative color of the raster object; and a visibility determination unit that determines a visibility of an overlapping portion based on a comparison of output color values.
