Abstract
A calibration target curve with less error is provided even when the number of points to be edited of the calibration target curve is small. An efficient and accurate method for editing or generating the calibration target curve is also provided. For this purpose, on the basis of specified input data values versus a plurality of predetermined output density values, there is generated a calibration target curve which shows the correspondence relation from the input data values to the output density values.
