PROBLEM TO BE SOLVED: To make the gradation properties of a display device close to targeted gradation properties on the basis of a result of photographing by a photographing device without using properties characteristic to the photographing device.SOLUTION: A first test image containing plural images different in color is displayed on a display screen 31 of a display device 30, and a displayed image containing the displayed first test image is photographed by using a digital camera 60 to obtain first imaging data. First test imaging data corresponding to the first test image is cut out of the first imaging data, and the output gradation values of respective RGB colors of plural images in the first test imaging data are normalized to obtain first normalized data. Gradation correction data of the RGB colors corresponding to the display device 30 is generated on the basis of the first normalized data. |
