Abstract: According to an aspect of an embodiment of the disclosure, an electronic device includes: a photographing device; a memory storing one or more instructions; and at least one processor configured to execute the one or more instructions stored in the memory to capture a first image by using the photographing device, perform first adjustment on an exposure value based on the first image, when the first image does not satisfy a first condition, perform second adjustment on the exposure value based on a second image acquired by applying a mask having a high weight for a region of interest to the first image, when the second image does not satisfy a second condition, adjust at least one photographing setting value based on the adjusted exposure value, and capture, by using the photographing device, a third image based on the adjusted at least one photographing setting value.

Abstract: Various embodiments of the present disclosure may store instructions to perform image recognition for a plurality of images, calculate similarity between the plurality of images, based at least partially on a result of the image recognition, create a group including at least two images of the plurality of images, based at least partially on the calculated similarity, determine a sequence for displaying, the at least two images included in the group, based at least partially on similarity between the at least two images included in the group, and output the at least two images onto the display in the sequence. In addition, various other embodiments are possible.

Abstract: An iris-based authentication method is provided. The method includes emitting light of an infrared wavelength band and obtaining an image based on the light of the infrared wavelength band, determining whether a specified condition is satisfied, if the specified condition is satisfied, performing user authentication (e.g., complex authentication) based on at least part of a face image and an iris image of the image that a biometric sensor obtains, or, if the specified condition is not satisfied, performing the user authentication (e.g., iris-only authentication) based on the iris image in the image that the biometric sensor obtains.

Abstract: An apparatus for recognizing an iris is provided. The apparatus includes an image acquisition module configured to acquire a plurality of images, and a processor configured to select at least one image for iris recognition from among the plurality of images based on pupil information of each of the plurality of images, and recognize an iris in at least one image, wherein the pupil information includes at least one of information about a pupil radius and information about a pupil contrast.

Abstract: A user recognition method that uses an iris is provided. The user recognition method includes generating a first mask for blocking a non-iris object area of an iris image, generating a converted iris image, in which the non-iris object area is blocked according to the first mask, generating a second mask for additionally blocking an inconsistent area, in which quantization results of the converted iris image are inconsistent, by adaptively transforming the first mask according to features of the converted iris image, obtaining an iris code by quantizing pixels included in the iris image, obtaining a converted iris code, in which portions corresponding to the non-iris object area and the inconsistent area are blocked, by applying the second mask to the iris code, and recognizing a user by matching a reference iris code, stored by the user in advance, to the converted iris code.

Abstract: An electronic device is provided. The electronic device includes an iris recognizing unit that extracts an iris area from one frame of a preview image and performs iris authentication by comparing a feature of the iris area with registered iris information and a processor that determines a match, a no-match, or an iris recognition error based on one of an amount of times that the iris authentication is performed during a first time period and a result of the iris authentication during the first critical time period.
