摘要

PROBLEM TO BE SOLVED: To provide an apparatus for detecting eye opening degree which precisely detects eye opening degree by appropriately preventing an erroneous detection of the lower eyelid.

SOLUTION: The apparatus 100 for detecting eye opening degree comprises an imaging means 120 for photographing the subject's face, an edge extracting means for extracting edges of the captured image, and an upper and lower eyelid detecting means for detecting the upper and lower eyelids of the subject on the basis of the extracted edges. The apparatus detects the eye opening degree of the subject on the basis of the distance between the detected upper and lower eyelids. The apparatus is characterized by that the upper and lower eyelid detecting means first detects the upper eyelid and then detects the lower eyelid on the basis of the detected upper eyelid.
