Zusammenfassung:	PROBLEM TO BE SOLVED: To execute factorization even if low-reliability data exist in an observation matrix (a feature-point position series), as to a three-dimensional shape restoration device. SOLUTION: In factorizing the observation matrix W, a reliability matrix Q is used which expresses the reliability (variance of probability distribution (normal distribution) expressing the position of a feature point) of respective observation values xtconstituting the observation matrix W. By causing the variance Σsof test distribution q(S) of a shape matrix to reflect the reliability matrix Q, factorization is performed in which the higher the reliability of feature points is, the more they are emphasized.
