摘要： PROBLEM TO BE SOLVED: To provide an apparatus capable of accurately detecting an eyelid without being affected by a light environment. SOLUTION: A camera 2 continuously photographs a subject's face and a control unit 14 of the eyelid detection apparatus 10 obtains that face image and stores it in an image memory 12. The control unit 14 identifies an eyelid search area from the face image, extracts edges from within the eyelid search area, and labels each of the connected edges (edge groups). Then the control unit 14 identifies the same edge groups according to changes in the movement of the labeled edge groups over time, and performs relabeling by which the same edge groups are given the same label. The control unit 14 detects the edge group that corresponds to the top eyelid based on the changes in the movement over time of the edge groups thus labeled, and detects the edge group that corresponds to the bottom eyelid from a predetermined area below the detected edge group that corresponds to the top eyelid.

摘要： A computer (30) obtains a facial image acquired by picking up an image of a person subjected to image pickup from a camera (10), and estimates a facial expression of the person subjected to image pickup based on the obtained facial image. Next, the computer obtains an eye open level of the person subjected to image pickup based on the facial image, and sets a threshold of the eye open level based on the estimated facial expression of the person subjected to image pickup. When the eye open level exceeds the threshold, the computer (30) determines that the eye of the person subjected to image pickup is opened. Moreover, when the eye open level does not exceed the threshold, the computer determines that the eye of the person subjected to image pickup is closed.

摘要： PROBLEM TO BE SOLVED: To provide a driver monitor monitoring a driver by use of an image even when an object blocks an imaging part. SOLUTION: The driver monitor monitoring a driver by use of an image includes: an image sensor 31 capturing the image of the driver; and an ECU (Electronic Control Unit) 2 detecting a hidden area R H that includes a handle in the image based on movement of the handle interposed between the driver and the image sensor 31, and searching an image area excluding the hidden area R H in the image to track a characteristic point of the driver. The driver monitor searches the image area excluding the hidden area R H in the captured image to track the characteristic point of the driver, so that the driver can be monitored with high accuracy even when the handle or the like blocks the image sensor 31.

摘要： PROBLEM TO BE SOLVED: To provide an eye opening degree determining device and an eye opening degree determining method, capable of accurately detecting the eye opening degree of a subject by removing the influence of disturbance. SOLUTION: The biological state detecting device 10 includes an eye opening degree detecting part 20 for acquiring the eye opening degree data of the subject based on the captured image of the subject's eyes, and an closed eye/opened eye determining part 24 for determining the eye opening degree of the subject based on the eye opening degree data acquired by the eye opening degree detecting part 20. The closed eye or opened eye determining part 24 determines the eye opening degree of the subject based on eye opening degree data selected by a false detection section estimating part 22 according to the difference in the eye opening degree between right and left eyes represented by the eye opening degree data among the eye opening degree data acquired by the eye opening degree detecting part 20. As it is not so often that the eye opening degrees are different between the right and left eyes, and as the difference in the eye opening degree between the both eyes is closely related to the disturbance, the eye opening degree of the subject can be more accurately detected by detecting the eye opening degree of the subject based on the eye opening degree data selected according to the difference in the eye opening degree between the both eyes and removing the influence of the disturbance.

摘要： PROBLEM TO BE SOLVED: To provide an instrument for estimating sleepiness which permits sleepiness to be more accurately estimated and a method for estimating sleepiness.SOLUTION: In the sleepiness estimating instrument 10, a closed-eyes and opened-eyes decision section 15 detects an opened-eyes condition and a closed-eyes condition based on the degree of opening of the eyes and computes time Tclose required for the change from the opened-eyes condition to the closed-eyes condition and time Topen required for the change from the closed-eyes condition to the opened-eyes condition. An erroneous detection section estimation section 16 decides that the opening and closing action of the eyes is a blink at the time when the relation of Tclose≤Topen is satisfied. Furthermore, only the feature amount of the blink of the opening and closing actions, when the erroneous detection section estimation section 16 decides that the actions are the blink, is used for estimation of sleepiness by a sleepiness estimation section 18. Thus by deciding about the blink by Tclose and Topen based on the degree of opening of the eyes, the instrument effectively reduces the erroneous detection of the blink at the time of sleepiness estimation.

摘要： PROBLEM TO BE SOLVED: To provide an image monitoring apparatus capable of searching a face position from an image in a short period of time. SOLUTION: An ECU 20 for searching a face position of a driver from a captured image that is imaged by an image sensor 10 includes a face position early stage finding part 21 for finding (searching) the face position of the driver from the whole captured image acquired by the image sensor 10 and preparing a template, a face position tracking part 22 for tracking the face position of the driver in the captured image by template matching and updating the template, a face search position setting part 23 for setting a search area for searching the face position in the captured image, and a face position history recording part 24 for recording a search history of the face position and preparing a two-dimensional frequency histogram H (x, y). When fails in tracking the face position, the ECU 20 searches the face position in order of coordinates (x, y), the number of searching times of which is large with reference to the two-dimensional frequency histogram H (x, y).
