Our purpose was to reveal a relationship between subjective evaluation for indistinct Mura of display and two-dimensional luminance distribution characteristics of Mura images. We conducted an experiment to evaluate indistinct Mura images using the magnitude estimation method. The results suggested that three numerical indexes would be important for the subjective evaluation for indistinct Mura. The indexes were (1) number of pixels which were 200 or less in 256 gray scale levels, (2) sum of edge areas, and (3) sum of edge boundary lengths. Each index would correspond to the area that observers could recognize as Mura, the area with luminance change in Mura images, and complexity in shape of that area.
