Claim:
1. An image processing apparatus comprising: a processor; and a memory including instructions that, when executed by the processor, cause the processor to perform operations including: when a density value of a black component in uncorrected monochrome image data corresponding to each of pure colors including primary colors and secondary colors in color image data is lower than a reference density value, the uncorrected monochrome image data being obtained by a monochrome conversion from the color image data including pixel values of respective color components for each pixel to monochrome image data including a density value of a black component for each pixel, determining a correction content for correcting the density value of the black component in the uncorrected monochrome image data corresponding to at least each of the pure colors out of the pure colors and peripheral colors of the pure colors in a color space to a value equal to or higher than the reference density value; and obtaining corrected monochrome image data in which correction based on the determined correction content is reflected in the uncorrected monochrome image data.
