摘要： Certain embodiments provide a biometric recognition apparatus and a method for lowering false recognition rate of biometric information in an electronic device adopting biometric recognition technology. In doing so, the electronic device may store first feature values extracted at M-ary feature points from owner biometric information, and additionally store auxiliary biometric information from a biometric information stored in one or more memories or an external server. The electronic device may perform biometric recognition on input biometric information using the first feature values and second feature values extracted from the biometric information additionally stored.

摘要： An electronic device for iris recognition and an operating method thereof are provided. The electronic device includes a housing including a first surface, a display exposed through a first region of the first surface, a light emitting unit comprising light emitting circuitry disposed in a second region of the first surface, an image device comprising image acquiring circuitry disposed in a third region of the first surface, at least one processor disposed within the housing and electrically connected with the display, the light emitting unit and the image device, and a memory disposed within the housing and electrically connected with the at least one processor. The memory stores instructions that, when executed by the processor, cause the electronic device to store a reference template based on a first iris image which has been recognized using the light emitting unit and the image device, to authenticate a second iris image which has been recognized using the light emitting unit and the image device, using the stored reference template, and to store a template of the second iris image succeeded in authentication, as an additional template.

摘要： A full-chip cell critical dimension (CD) correction method and a method of manufacturing a mask by using the same are provided. The full-chip cell CD correction method includes receiving a database (DB) about a full-shot; analyzing a hierarchy of the DB; generating a density map of a full-chip by using the DB and converting the density map into a retarget rule table, the converting including mapping the density map by using a density rule; reconfiguring cell blocks of the full-chip into an optical proximity correction (OPC) target cell layout for OPC; applying a first bias to the OPC target cell layout, based on the retarget rule table; and generating an optical proximity corrected (OPC'ed) layout for the full-chip by performing hierarchical OPC.

摘要： Disclosed is an electronic apparatus including a first camera, a second camera, and a processor. The first camera includes a first FOV. The second camera includes a second FOV corresponding to part of the first FOV. The processor is configured to obtain a request associated with biometric authentication. The processor is configured obtain at least one first image using the first camera and at least one second image using the second camera. The processor is configured to identify a first external object that is included in the at least first image while obtaining the first image. While obtaining the at least one second image, the processor is configured to provide notification information for obtaining at least one image including the second external object when the second external object that is at least part of the first external object, is not included in the at least second image.
