An eye part detecting device has an image input section () for acquiring a face image, an eyelid edge labeling section () for detecting upper eyelid candidates and lower eyelid candidates which satisfy predetermined conditions for upper eyelids or lower eyelids in the face image, and an eyelid determination section () for comparing combinations of the upper and lower eyelid candidates to determine the combination of the upper and lower eyelid candidates whose relation best satisfies a predetermined condition as the upper and lower eyelids. The eyelid edge labeling section () classifies the horizontal edges and vertical edges calculated by an edge calculating section () 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 () 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 () 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.

Eye detecting device, eye detecting method, and program

An eye opening detection system that includes an imaging mechanism that captures an image of the face of a detected subject, an edge extraction mechanism that extracts the edge of the image captured, and an upper and lower eyelid detection mechanism that detects the upper and lower eyelids of the detected subject according to the edge extracted, and that detects the eye opening of the detected subject with reference to a detected distance between the upper and lower eyelids. The upper and lower eyelid detection detects the upper eyelid and detects the lower eyelid with reference to the upper eyelid detected.

Eye opening detection system and method of detecting eye opening

An eyelid detection apparatus includes a face image storing means storing a plurality of face images of a subject captured at different timings, a change detecting means detecting changes in each face image caused by blinking after processing the plurality of face images stored by the face image storing means, and an eyelid detecting means detecting a position of an eyelid of the subject based on the changes detected by the change detecting means.

Eyelid detection apparatus and programs therefor

An obstacle detecting portion () on a vehicle detects an obstacle behind the vehicle. A CPU () detects the direction of the driver's line of sight based on a driver's face image captured by a camera (). The CPU () determines whether the direction of the driver's line of sight directed to mirrors (L,R) reflecting an image of the obstacle behind the vehicle. According to the result of the determination, the CPU () sets the level of an alarm to be outputted by warning signal outputting portions ().

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.
