Publication number: 20120148116Abstract: Provided is an apparatus for identifying person's identity. User's eyeballs may be precisely located in an operation region of the apparatus for identifying the person's identity, i.e., a photograph region in which an iris image of a user to be identified by the camera can be photographed using an indicator provided by the apparatus for identifying the person's identity. Also, a limitation in which the user's eyeballs are located at positions different from each other due to person's parallaxes different from each other even though the indicator is provided at the same position may be solved to locate the eyeballs of the user to be identified using the apparatus for identifying the person's identity at the same position.Type: ApplicationFiled: July 28, 2010Publication date: June 14, 2012Inventor: Jang Jin Chae

Patent number: 7146027Abstract: Disclosed is a method to improve iris recognition success ratio and speed by registering the iris code on location of illuminator. In the present invention, iris codes for a single iris generated as many as the number of a plurality of illuminators are registered on an iris database every area corresponding to the location of the illuminator. The iris codes generated one by one whenever the plurality of illuminators are turned on one by one for recognition are searched on the corresponding areas of the iris database to determine the recognition.Type: GrantFiled: December 27, 2002Date of Patent: December 5, 2006Assignee: LG Electronics, Inc.Inventors: Ho Kim, Jang Jin Chae

Patent number: 7095901Abstract: The present invention relates to a method for adjusting a focus position in an iris recognition system, the method including the steps of: projecting a designated light for measuring a distance between the user and a camera; acquiring user images including the image projected by the light; and measuring a distance between the user and the camera by extracting the projected image by the light out of the user images and analyzing characteristics of the image. In addition, the present invention relates to an apparatus for adjusting a focus position in an iris recognition system, which enables to adjust the focal angle of an iris, the apparatus includes an illumination device; an iris recognition camera for acquiring user images having an iris image when the illumination device irradiates a light; an illuminator for helping the user with the focal angle according to sharpness of the visible ray that depends on the focal angle by transmitting a visible ray from the illuminator and by reflecting the user images.Type: GrantFiled: March 14, 2002Date of Patent: August 22, 2006Assignee: LG Electronics, Inc.Inventors: Won Hee Lee, Ae Kyung Yang, Jang Jin Chae

Patent number: 6652099Abstract: The invention relates to an iris recognition system, and more particularly, to an apparatus for approaching the iris images of the both eyes most adjacent within a range beyond which the iris images overlap each other in an iris recognition system using all of the iris images of the both eyes at the same time. The iris recognition system using all of the iris images of the both eyes at the same time adopts an apparatus for narrowing the distance between the iris images of the both eyes acquired in CCD images when the iris images are obtained through photographing the iris images of the both eyes are photographed. The apparatus of the invention comprises iris image focusing means for converting an incident path, whereby the distance between the iris images of the both eyes is narrowed on an optical path along which eye images of the user are focused to a camera, in which the focusing means can be an angled reflector with one side being inclined at an angle about the center.Type: GrantFiled: November 16, 2001Date of Patent: November 25, 2003Assignee: LG Electronics, Inc.Inventors: Jang Jin Chae, Seung Gi Min

Publication number: 20030156741Abstract: The present relates to an eye position display housed in an iris recognition system and a method thereof. Particularly, the iris recognition system comprises: a board (PCB) including a controller for controlling emission of light; a light emitter with a LED mounted on the PCB for emitting a light and uniformly scattering and equalizing the intensity of the emitted light; a lens unit for maintaining a focal length of the emitted light from the light emitter, refracting and converging the light at a constant angle, and passing the light through a predetermined portion only so as to display a position where a user's eye is should be; and a reflector unit for reflecting every wavelength band that passed through the lens unit except for a wavelength of a predetermined light.Type: ApplicationFiled: February 20, 2003Publication date: August 21, 2003Applicant: LG Electronics Inc.Inventors: Won Hee Lee, Jang Jin Chae

Patent number: 6594377Abstract: The present invention relates to an iris recognition system which can extract an iris image of the user, by upwardly and downwardly rotating around a hinge bracket in order to be exactly rapidly controlled to a position of the user's eyes. The conventional iris recognition system has disadvantages in that the system size is huge, the time for obtaining the iris image is quite long, and the system is difficult to handle.Type: GrantFiled: January 10, 2000Date of Patent: July 15, 2003Assignee: LG Electronics Inc.Inventors: Bum Chul Kim, Jang Jin Chae

Publication number: 20030118212Abstract: Disclosed is a method for registering Iris code in an Iris recognition system to avoid inconvenience of re-registration when a new Iris algorithm is applied. The method for registering Iris code includes the step of: when an old Iris code was registered on an Iris code database of the Iris recognition system to which the old Iris algorithm is applied, registering a new Iris code on the Iris code database, the new Iris code being generated using a new algorithm provided in the Iris recognition system. Accordingly, even though an Iris algorithm is changed in an Iris recognition system, the users do not have to register their Iris codes again and time to register Iris codes again are not wasted.Type: ApplicationFiled: December 20, 2002Publication date: June 26, 2003Applicant: LG Electronics Inc.Inventors: Seung Gi Min, Jang Jin Chae
