Abstract:
1. An image processing apparatus, comprising: an adjusting unit configured to convert input color image data into color image formation data; an arithmetic unit configured to calculate a color image formation ink cost based on the converted color image formation data; and a first determining unit, including a processor, configured to compare the calculated color image formation ink cost with a black-and-white image formation ink cost, wherein when a comparison in the first determining unit does not satisfy a predetermined condition, the calculated color image formation ink cost is adjusted by modifying the converted color image formation data based on a determination result of the first determining unit; and, wherein the adjusting unit corrects R, G, and B values of the input image data by multiplying the R, G, and B values by a coefficient p, p being equal to or greater than 0 and less than or equal to 1.0, according to R′=R_max−p×(R_max−R), G′=G_max−p×(G_max−G), and B′=B_max−p×(B_max−B), respectively, wherein R′, G′, and B′ represent corrected R, G, and B values, respectively, and R_max, G_max, and B_max represent maximum level values of the R, G, and B values, respectively, of the input image data.
