Claim One:
1. An information processing apparatus, comprising: a read image obtainer implemented by circuitry and configured to obtain a scanned determination image including a plurality of different dot patterns output by an image forming apparatus on a recording medium, the determination image being an image output by the image forming apparatus to determine output characteristics of the image forming apparatus; and a setting value calculator implemented by the circuitry and configured to for each of the different dot patterns of the obtained scanned determination image, determine densities of different colors of the respective dot pattern, and determine a total number of pixels influencing the density of each coefficient of a dot gain correction filter, with respect to each target pixel, and calculate the coefficients of the dot gain correction filter based on the determined densities of the different colors of the different dot patterns and the total number of pixels, determined for each coefficient of the dot gain correction filter and for each of the different dot patterns.
