摘要:
An eyelid detecting apparatus includes an image capturing portion for capturing a face image, a red-eye effect detecting portion for detecting a red-eye effect in which a light appears red at the pupil in the face image, the light entering through the pupil, reflecting on a choroidea of the eye, and exiting from the pupil, an eyelid detecting portion for detecting an upper eyelid and a lower eyelid in the face image on the basis of an edge appearing on a boundary between a bright portion and a dark portion and the eyelid detecting portion ignoring the edge of a red-eye effect occurring pupil so as not to be considered as the upper eyelid and the lower eyelid when the red-eye effect detecting portion detects the red-eye effect.
