摘要： According to an embodiment of the disclosure, there is provided a biometrics-based user authentication method including: obtaining a user's biometric image, obtaining a shallow biometric feature from the user's biometric image by using a first neutral network of a learning network model, obtaining a deep biometric feature from the user's biometric image by using a second neutral network of the learning network model, determining a similarity between the shallow and deep biometric features and a valid user's biometric features stored in advance, and determining whether the user matches the valid user, based on the determined similarity.

摘要： An image sensor includes an active pixel array, at least one dummy reset array, a dummy read array, and an image processor. The image processor sequentially resets respective rows of pixels included in the at least one dummy reset array in a period in which pixels of the active pixel array do not perform a reset operation, and sequentially reads respective rows of pixels included in the dummy read array in a period in which the pixels of the active pixel array do not perform a read operation.

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.

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： In some embodiments, an imaging device includes a pixel array. At least one of the pixels includes a photodiode that can generate charges, and a select transistor that receives the charges in its bulk. When the select transistor is selected, a pixel current through it may depend on a number of the received charges, thus evidencing how much light it detected. A reset transistor may reset the voltage of the bulk.
