Abstract:
A method and device for controlling an irradiating light for photographing an iris is provided. The device includes a light source configured to generate light, an active lens configured to adjust a refractive index of light passing through the active lens, an image capturer configured to capture an image of the iris by using a camera, and a controller configured to control the active lens to change the refractive index of the light passing through the active lens based on distance, motion and ambient light levels.
Abstract:
A vehicle display device and a control method thereof are provided. The present vehicle display device comprises: a camera for photographing a driver; a sensing unit for measuring the distance to an external object; a display for providing operating information of a vehicle; and a processor, which analyzes an image captured through a camera so as to track a driver's gaze, determines an external object present at the location at which the tracked driver's gaze is directed, calculates the distance to the determined object through the sensing unit, and controls the display such that the operating information is displayed on the basis of the driver's gaze and the distance to the object.
Abstract:
A user authentication method for an electronic device is provided. The user authentication method includes detecting a content execution event, confirming an authentication level of content related to the detected content execution event, acquiring an appearance image through a camera unit, extracting valid regions related to an iris of a user from the acquired appearance image, and performing an authentication on the user by comparing iris authentication reference information related to a confirmed authentication level with the extracted valid regions.
Abstract:
A user terminal and a providing method thereof are provided. The method includes acquiring an iris image, determining a capturing condition of the iris image, converting the acquired iris image to an iris code and performing iris recognition by comparing the converted iris code with an iris code corresponding to a determined capturing condition among pre-registered iris codes, determining a physical condition of a user who is subject to the iris recognition on the basis of an iris recognition matching rate being within a preset range, and providing a determined physical condition result.
