Abstract
The present invention provides a technology that acquires a high resolution iris image more quickly than before. An iris capture apparatus according to one example embodiment of the present invention includes a rotatable movable mirror; a control unit that controls rotation of the movable mirror; a capture unit that captures different regions of a face of a user via the movable mirror and outputs a group of images every time the control unit rotates the movable mirror by a predetermined angle; and an iris image acquisition unit that acquires an image of an iris of the user from the group of images.
Claims11
An iris capture apparatus comprising:
- a processor configured to:
- activate a human sensor;
- acquire, after the human sensor has detected a user, a first image, the first image depicting an iris of the user, by rotating a rotatable movable mirror, using a motor, of the iris capture apparatus in a first direction;
- determine whether the iris is depicted in the first image;
- rotate the rotatable movable mirror again, using the motor, in response to the iris not being depicted in the first image, to acquire a second image;
- and
- recognize the user based on an acquired image of the iris,
- wherein the processor is configured to capture a third image, the third image depicting iris of the user, from the second image,
- wherein the rotatable movable mirror of the iris capture apparatus is rotatable about a first axis, and wherein the processor is configured to rotate the rotatable movable mirror of the iris capture apparatus about the first axis for a predetermined number of times.
A method of iris capturing comprising:
- activating a human sensor;
- acquiring a first image after the human sensor has detected a user, the first image depicting an iris of the user, by rotating a rotatable movable mirror, using a motor, of the iris capture apparatus in a first direction;
- determining whether the iris is depicted in the first image;
- rotating the rotatable movable mirror again, using the motor, in response to the iris not being depicted in the first image, to acquire a second image;
- and
- recognizing the user based on an acquired image of the iris,
- wherein the method further comprises capturing a third image, the third image depicting iris of the user, from the second image,
- wherein the rotatable movable mirror of the iris capture apparatus is rotatable about a first axis, and wherein the method further comprises rotating the rotatable movable mirror of the iris capture apparatus about the first axis for a predetermined number of times.
A non-transitory computer readable medium having stored therein a program for performing a method of iris capturing comprising:
- activating a human sensor;
- acquiring a first image after the human sensor has detected a user, the first image depicting an iris of the user, by rotating a rotatable movable mirror, using a motor, of the iris capture apparatus in a first direction;
- determining whether the iris is depicted in the first image;
- rotating the rotatable movable mirror again, using the motor, in response to the iris not being depicted in the first image, to acquire a second image;
- and
- recognizing the user based on an acquired image of the iris,
- wherein the method further comprises capturing a third image, the third image depicting iris of the user, from the second image,
- wherein the rotatable movable mirror of the iris capture apparatus is rotatable about a first axis, and wherein the method further comprises rotating the rotatable movable mirror of the iris capture apparatus about the first axis for a predetermined number of times.
