摘要：A calibration system includes an imaging device, an image forming apparatus,and a table generating section. The image forming apparatus prints a test chartcontaining patches of colors on a sheet. The imaging device captures images of a

reference chart containing patches corresponding to the patches in the test chart andthe test chart on the sheet together to generate a picture. The table generating section:calculates a weighting coefficient for each of the patches in the picture based on a colorintensity of the patch; calculates, as a representative value for each of gradations of colorvalues of the patches in the picture, a weighted average of color values of the patches inthe gradation based on the weighting coefficient; and generates a gamma correctiontable for correcting gradation characteristics of the image forming apparatus togradation characteristics in accordance with the reference chart based on therepresentative values.
