Abstract: An iris detection method includes acquiring a first image; generating a second image including an eye section of the person from the first image; generating a third image where pixels having a gradation value smaller than a threshold value are represented by a first luminance value and pixels having a gradation value equal to or greater than the threshold value are represented by a second luminance value after binarizing the second image; generating a fourth image by replacing the pixel of the second luminance value come into existence in a first luminance area having the first luminance value and satisfying a predetermined condition with the pixel of the first luminance value in the third image; calculating iris information including information about at least one of a position and a size of the iris of the person by use of the fourth image; and outputting the iris information.

Abstract: An information processing method includes: for each of one or more users, acquiring image data including an eye of each of the users; detecting eye gaze information indicating an eye gaze of each of the users based on information indicating the eye of each of the users included in the image data; performing personal authentication on each of the users based on information indicating the eye of each of the users included in the image data; acquiring personal information for identifying each of the users for which the personal authentication has been performed; generating management information in which the personal information of the one or more users and the eye gaze information of the one or more users are associated with each other; and outputting the management information.

Abstract: A viewing distance estimation method includes: acquiring a first image captured by an image capturing device and including a face of a person who watches a target; detecting a size of an iris of the person from the first image; calculating a first value indicating a pixel number for the detected size of the iris; acquiring a resolution of the first image; calculating, based on the first value and a second value indicating a predetermined inherent dimension for the size of the iris, a third value indicating an actual dimension of one pixel; estimating a viewing distance corresponding to the acquired resolution and the calculated third value, based on relational information representing a relation among the resolution, the third value, and the viewing distance; and outputting estimative information including the estimated viewing distance.

Abstract: A judgement method includes: selecting two or more living body judgement processes among a plurality of living body judgement processes; determining an order of executing the two or more selected living body judgement processes; executing the two or more selected living body judgement processes in the determined order; executing, in each of the two or more selected living body judgement processes: a processing of showing a subject an action required; a processing of acquiring a facial image containing a face of the subject when acting in accordance with the shown action; and a processing of judging whether the subject is of living body based on a feature of a section of the face contained in the facial image; and judging that the subject is of living body when judgement results obtained from the two or more selected living body judgement processes satisfy a predetermined condition.

Abstract: An eye detecting device is configured to: acquire a color image including a face of a person taken by an image taking device; generate a grayscale image by multiplying each of a red component value, a green component value, and a blue component value of each pixel of the color image by a predetermined ratio according to characteristics of a lens of glasses that the person wears; detect an eye of the person from the grayscale image; and output eye information on the eye of the person.

Abstract: A device for detecting opening and closing of an eye acquires a first image taken by an image taking device, including a face of a person; generates a second image including an eye region of the person from the first image; generates a third image in which pixels having a gradation value smaller than a threshold are represented at a first luminance value and pixels having a gradation value not smaller than the threshold are represented at a second luminance value, by binarizing the second image; determines whether the eye of the person is opened or closed, on the basis of a height of the third image and a maximum height which is the maximum of a vertical distance between an upper pixel and a lower pixel in a first luminance region having the first luminance value; and outputs information indicative of a result of the determination.

Abstract: An image processing method includes: detecting a position of a facial feature point of a person from the image data; detecting a center position of a pupil of an eye of the person from the image data; detecting a horizontal component and a vertical component of an orientation of the face based on the position of the feature point; estimating a horizontal component of an eye gaze direction of the person with respect to an optical axis of the imaging device based on the horizontal component of the orientation of the face and a distance between the center position of the pupil and the position of the feature point; estimating a vertical component of the eye gaze direction based on at least the vertical component of the orientation of the face; and outputting eye gaze information including the horizontal component and the vertical component of the eye gaze direction.
