    摘要: In an image forming apparatus according to the present invention, characteristics correcting data for correcting input gray level-output gray level characteristics for each of a plurality of steps into which input gray levels are divided are inputted by inputting means. At the time of image formation processing, input gray level-output gray level characteristic data are corrected on the basis of each of the characteristics correcting data (Sft) inputted by the inputting means.

    摘要: A color correcting device for applying a color correction to an image data made up of color components of three primary colors and read by a color image reader means, the device includes: an image data extractor for extracting an image data of a predetermined color to be corrected based on a density balance of the respective color components of three primary colors, and a corrector for correcting a density level of a specified color component set in advance in correspondence with the color to be corrected, out of the color components of the extracted image data, to a predetermined density level.
