摘要:A calibration system includes an imaging device, an image forming apparatus,and a table generating unit. The table generating unit: calculates a first weightingcoefficient based on dispersion of color values of pixels inside the patch in a capturedimage for each of the patches where the captured image is generated by simultaneouslycapturing the test chart of the sheet generated by the image forming apparatus and apreliminary prepared reference chart with the imaging device; calculates a representativevalue for each tone of the color value of each of the patches in the test chart and thereference chart based on an average of a weighted average of the color value of theplurality of patches; and generates the gamma correction table based on the respectiverepresentative values in the test chart and the reference chart.
