PROBLEM TO BE SOLVED: To provide a method and device that can convert the data of an image photographed by a digital camera under the same lighting through the estimation of a spectral characteristic of the lighting light and grasping information of a color reproduction characteristic, with respect to the lighting light at photographing into other image data especially being CIEXYZ image data or the like, while maintaining colorimetric information and while taking the color reproduction characteristic of various display and output devices into account and can acquire also image data for display and output, and to provide an information recording medium for its program. SOLUTION: Image data resulting from picking up a color chart attached standard board are analyzed, the spectral distribution of the lighting light is estimated, a database is used to identify and utilize the lighting light at photographing, so as to convert image data obtained by photographing under the same lighting and the same image pickup system into other image data. |
