Zusammenfassung:	PROBLEM TO BE SOLVED: To determine an occurrence place of color unevenness in an image displayed on a display unit of a display device.SOLUTION: A display unit 3 of a display device 1 to be inspected is captured by imaging means 5 to acquire image data, two-dimensional spectral data on radiation luminance are generated by data generation means 6 based on the image data, the two-dimensional spectral data are processed to color unevenness detection data by input data processing means 7, and color unevenness determination means 8 compares the color unevenness detection data with predetermined referential data and determines the occurrence place of color unevenness in an image displayed on the display unit 3 of a display panel.
