<P>PROBLEM TO BE SOLVED: To provide a color unevenness measuring method capable of quickly and accurately performing color unevenness measurement. Ž<P>SOLUTION: The color unevenness measuring method includes: a color-unevenness measurement image displaying step of displaying a color-unevenness measurement image displayed by a projector 2; a color-unevenness measurement image photographing step of photographing the displayed color-unevenness measurement image by a photographing device 3; a pixel selection step of selecting an inspection target pixel and a comparison pixel from captured image data; a color difference calculation step of calculating the color difference between these pixels based on color difference signals of the inspection target pixel and the comparison pixel selected in the pixel selection step; a color difference conversion step of converting the color difference calculated in the color difference calculation step to a second color difference corresponding to a uniform color space using a color difference distance conversion coefficient; and a color unevenness measurement step of measuring color unevenness based on the second color difference.
