PROBLEM TO BE SOLVED: To realize recognition of not only a category of expression but also a dynamical property of the expression.;SOLUTION: An expression recognition device comprises: input means for outputting position information of a plurality of feature points on a face from time-series image data; category padding means for calculating a category spatial coordinate by projecting the position information of the plurality of feature points to a category space of the expression; dynamic property padding means for calculating a dynamic property spatial coordinate by projecting the position information of the plurality of feature points to a dynamic property space; and expression recognition means for estimating the category of expression of an expression recognition target person by referring to pre-stored category variety information and specifying the category variety information to which the category spatial coordinate belongs, and estimating the dynamic property of the expression of the expression recognition target person by referring to pre-stored dynamic property variety information and specifying the dynamic property variety information to which the dynamic property spatial coordinate belongs.;COPYRIGHT: (C)2012,JPO&INPIT
