Eyelid detection apparatus, eyelid detection method and program therefor

摘要

An eyelid detection apparatus (50) includes a face-image storing apparatus (22) for storing an image of a face of a subject, an eyelid-candidate extracting apparatus (24) for processing the image stored in the face-image storing apparatus (22) to extract a pair of lines, which becomes a candidate of a combination of a line corresponding to an upper eyelid and a line corresponding to a lower eyelid, a parameter calculating apparatus (24) for calculating a parameter, which indicates a possibility that a part of the image stored in the face-image storing apparatus (22), the part corresponding to the pair of lines extracted by the eyelid-candidate extracting apparatus (24), includes at least one of outer and inner corners of an eye, and an eyelid detecting apparatus (24) for detecting a position of an eyelid of the subject on the basis of the parameter calculated by the parameter calculating apparatus (24).
