摘要： An image capturing section captures a face of an observed person. A position detecting section detects, from a face image expressing the face captured by the image capturing section, one of a position expressing a characteristic of a nose and a position expressing a characteristic of a region between eyebrows. A computing section computes a past relative position of a predetermined region of the face that is based on the position detected in the past by the position detecting section. A region position detecting section detects a position of the predetermined region on the basis of the past relative position computed by the computing section and the current position detected by the position detecting section.

The eyelid edge labeling section (24) classifies the horizontal edges and vertical edges calculated by an edge calculating section (23) into the upper eyelid candidates and the lower eyelid candidates according to a degree of how well the predetermined conditions are satisfied. A lower eyelid candidate evaluating section (26) may be provided for excluding a lower eyelid candidate when it has at least one horizontal edge present in a lateral direction of the lower eyelid candidate. A lower eyelid candidate discriminating section (25) may be provided for discriminating that of the lower eyelid candidates whose vertical edge does not satisfy the predetermined condition as a lower eyelid preliminary candidate.
