IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING PROGRAM

摘要

An image processing apparatus, which generates data for reproducing a color of a dot image formed by a printer using a first color material, in an image forming apparatus, includes a grayscale data generation unit that generates input grayscale data in which a grayscale value corresponding to a dot area ratio is stored in a peripheral part of a dot, and a grayscale value corresponding to a color of a dot portion of the dot image is stored in a core part surrounded by the peripheral part, on the basis of dot data indicating the dot image, and a color conversion unit that converts the input grayscale data into output grayscale data indicating a usage amount of a second color material used in the image forming apparatus.

1. An image processing apparatus which generates data for reproducing a color of a dot image formed by a printer using a first color material, in an image forming apparatus, the image processing apparatus comprising:
a grayscale data generation unit that generates input grayscale data in which a grayscale value corresponding to a dot area ratio is stored in a peripheral part of a dot, and a grayscale value corresponding to a color of a dot portion of the dot image is stored in a core part surrounded by the peripheral part, on the basis of dot data indicating the dot image; and a color conversion unit that converts the input grayscale data into output grayscale data indicating a usage amount of a second color material used in the image forming apparatus, wherein the color conversion unit performs first color conversion on the grayscale value of the core part and performs second color conversion different from the first color conversion on the grayscale value of the peripheral part.
