Patent number: 11931489Abstract: A sterilization apparatus includes a main body, and a plurality of sterilization modules. The main body defines a sterilization space for sterilization of a sterilization target. The sterilization modules are disposed on a plurality of inner surfaces of the main body surrounding the sterilization space, respectively, and deliver germicidal light to the sterilization space. In addition, the sterilization module includes a support member and a plurality of light sources. A space between adjacent light sources disposed in some regions of the support member is different from a space between adjacent light sources disposed in the other regions of the support member.Type: GrantFiled: August 12, 2021Date of Patent: March 19, 2024Assignee: SEOUL VIOSYS CO., LTD.Inventors: Eun Ju Kim, Chung Hoon Lee, Jae Young Choi

Patent number: 9495580Abstract: A face recognition apparatus and method using plural face images includes detecting a reference face image from an image input for registration in advance, calculating plural face feature information from a frontal face image if the detected reference face image includes the frontal face image, generating plural compared face images using the calculated plural face feature information, and determining whether the input face image matches the generated plural compared face images by comparing the input face image with the plural compared face images. Face images having diverse points of view are generated through single user registration, and thus the face recognition ratio can be heightened.Type: GrantFiled: February 23, 2011Date of Patent: November 15, 2016Assignee: Samsung Electronics Co., LtdInventors: Hong-Il Kim, Sung-Dae Cho, Chung-Hoon Kim, So-Yeon Kang

Patent number: 8543940Abstract: A method and apparatus for browsing media content and executing functions related to the media content are provided. Under the state that a collage image generated by combining a plurality of image elements corresponding respectively to a plurality of media contents is displayed, if a selection input is generated on the collage image, a preview window for a media content corresponding to a location of a point where the selection input is generated is configured to overlay the preview window on the collage image. If a function execution input is generated on the collage image, a representative function is performed using a media content corresponding to a location of a point where the function execution input is generated.Type: GrantFiled: October 25, 2010Date of Patent: September 24, 2013Assignee: Samsung Electronics Co., LtdInventors: Nitin Singhal, Sung-Dae Cho, Chung-Hoon Kim, Yoon-Choon Hwang

Publication number: 20110141257Abstract: A facial image registration apparatus and method are provided for registering a plurality of facial images to be used for face recognition. A plurality of facial images are detected and sorted from a plurality of captured images input from a camera unit at the request of a user. A face feature value is calculated for each of the facial images. The face feature value is a score that is applied according to face features of each of the facial images. Facial images selected according to the calculated face feature values are registered as target facial images to be used for face recognition. As such, various facial images may be registered at a user's single request, thus improving a face recognition rate.Type: ApplicationFiled: December 15, 2010Publication date: June 16, 2011Applicant: Samsung Electronics Co., Ltd.Inventors: Yoon-Choon Hwang, Sung-Dae Cho, Byung-Jun Son, Tae-Hwa Hong, Chung-Hoon Kim, Nitin Singhal
