WIPO Patent Application WO/2017/175455
Kind Code:

Abstract:
The present invention: displays, on an image display device 4, a luminance evaluation image 1 provided with a determination portion 3 configured such that luminance changes progressively between a low-luminance region 3a in which the luminance is defined to be lower than the upper limit of displayable luminance of the image display device 4 and a high-luminance region 3b in which the luminance is defined to be higher than the upper limit of displayable luminance of the image display device 4 and/or a chromaticity evaluation image provided with a determination portion configured such that saturation of color changes progressively between a low-saturation region in which the saturation is defined to be lower than the upper limit of displayable saturation of the image display device 4 and a high-saturation region in which the saturation is defined to be higher than the upper limit of displayable saturation of the image display device 4; and evaluates the characteristics of the image display device 4 from the position of a boundary B1 in the determination portion 3.
