Area e, particle diameter d, and projection area Ej of the entire granular members are detected from the contour of each granular member s, for each spread-out picture Gj. The accumulated passage rate Pj(di) for a predetermined particle diameter di is calculated from the particle diameter d of each granular member s for each the picture Gj. The accumulated passage rate Pj(di) for the predetermined particle diameter di of the granular material S prior to the partition is measured based on the averaged area (=(ΣPj(di)*Ej)/ΣEj) of the accumulated passage rate Pj(di) across the entire pictures for the predetermined particle diameter di weighted by the projection area Ej for each spread-out picture Gj. Preferably each of the partitioned granular member groups Sj is spread out so as to have a constant surface density or constant thickness, into a rectangular area having a side length one to three times the maximum particle diameter of the granular members in the granular material S.
