An image correction method obtains scanned image data by photoelectrically reading a proof print obtained from original image data representing an original image. The method carries out a first color conversion for obtaining converted scanned image data by converting the scanned image data into a common color space corresponding to color perception; calculates a relationship between data values of the converted scanned image data and data values of the original image data as a color correspondence relationship; carries out a second color conversion for obtaining converted original image data by converting the original image data into the common color space based on the color correspondence relationship; carries out a third color conversion for obtaining print image data by converting the converted original image data from the common color space into a color space for printing; and obtains a print based on the print image data.
