Zusammenfassung:An analysis unit determines at least two boundaries by determining; in a coordinate system indicating a correlation between a luminance contrast value between a luminance of an attention portion and a luminance of a background portion, and a luminance average value of a visual target including the attention portion and the background portion; the boundary between a region where a subject has a visibility and a region where the subject does not have the visibility for each combination of stimulus values of a color stimulus of a visual target.
