15. The system of claim 10, wherein the correlation analyzing unit performs a multiple regression analysis in which the indices for the plurality of groups are used as dependent factors and the objective parameter candidates are used as independent factors.
16. The system of claim 10, wherein the correlation analyzing unit represents the indices or the degree of fatigue by objective parameters exceeding a predetermined significance probability from among the objective parameter candidates.
17. The system of claim 10, wherein the objective parameter candidates include crosstalk, field of view, focus distance, distance, scale, rotation, biocular brightness, monocular brightness, biocular contrast, monocular contrast, biocular sharpness, or monocular sharpness.
