PROBLEM TO BE SOLVED: To visualize a vector field onto a two-dimensional field of vision in a substantially intuitively visible way, including its local three-dimensional attribute. SOLUTION: The vector field (70) is mapped onto a three-dimensional coordinate space (80) to produce corresponding coordinate point sequences (P1); the degree of elevation (A) in the local area of a plane, in which the coordinate point sequences are connected, is determined (P2); the degree of depression (C) in the local area, in which the coordinate point sequences are connected, is determined (P3); the degree of elevation/depression (B) in the local area, in which the coordinate point sequences are connected, is determined by weight-combining the degree of elevation (A) and the degree of depression (C) (P4); the coordinate space (80) is mapped onto a two-dimensional plane (90); and gray-scale display (F) corresponding to the degree of elevation/depression is conducted on the area of the two-dimensional plane (90), corresponding to the local area in which the coordinate point sequences are connected (P5).
