Patent number: 10798278Abstract: Disclosed are an ultraviolet mirror device and a method therefor. The ultraviolet mirror device of the present invention relates to a device that can generate an image obtained by capturing an image of skin in the ultraviolet region. The device can be connected to a portable terminal having a display unit, so as to be used as an ultraviolet mirror. To this end, the ultraviolet mirror device includes an ultraviolet filtering unit provided in a front portion or a rear portion of the lens unit to allow ultraviolet light to pass therethrough and thus enter the image sensor; and an image processing unit providing the portable terminal with multiple digital images generated at a predetermined frame rate per second by the image sensor and thus allowing a moving image to be regenerated in the display unit.Type: GrantFiled: May 26, 2017Date of Patent: October 6, 2020Assignee: UNION COMMUNITY CO., LTD.Inventors: Young Hyun Baek, Yo Shik Shin

Publication number: 20110013812Abstract: An entrance control system having a camera, and a method thereof of controlling entrance are provided. The entrance control system not only controls entrances through a use of an authentication tool based on biometric recognition, but also photographs a person attempting an entry through the camera, maps the information into authentication history and manages the history data. Accordingly, the entrance control system is capable of rejecting an unauthorized person who has forged biometric information such as a forged fingerprint. In order to ensure a reliability of image record of the person, the system processes a facial recognition algorithm to determine if a frontal face of the person is captured, and controls so that an error message is provided to the person if there is an error, and authentication based on biometric recognition is processed only when the face of the person is captured within an image range.Type: ApplicationFiled: July 13, 2010Publication date: January 20, 2011Applicant: Union Community Co., Ltd.Inventors: Yo-shik Shin, Geum-yong Kim, Young-Hyun Baek
