PROBLEM TO BE SOLVED: To determine a camera parameter from locus data of four vertexes of a rectangle, and to stick a projected image of a two-dimensional object on the rectangular part. SOLUTION: When determining the camera parameter of a photographing device by inputting projected image positions (Ui(t), Vi(t)), (i=1-4) of the vertexes of a three-dimensional rectangular body photographed by the photographing device, variables Tx(t), Ty(t), Tz(t),α(t),β(t),γ(t), f(t) and R, Q, satisfying the mathematical expression 1 (a) are determined, and the position (Tx(t), Ty(t), Tz(t)) of a camera, the direction (α(t),β(t),γ(t)) of the camera and the focal distance f(t) of the camera are outputted.
