Image processing apparatus performing color conversion process that reflects intention of original color scheme, and control method therefor

摘要

An image processing apparatus that is capable of converting an original color image into a monochrome image to which color scheme intention of the original color image is reflected appropriately. An extraction unit extracts colors used for characters and figures in color data. A first determination unit determines one of the colors as a base color. A second determination unit determines another of the colors as an accent color. An application unit converts the color data into monochrome data by applying a predetermined gray to the base color determined and applying a gray that is distinguishable from the predetermined gray and has a density higher than the predetermined gray to the accent color.
