    Abstract: A head-mounted display apparatus is provided. The head-mounted display apparatus includes at least one camera, at least one sensor, and at least one processor operatively connected to the at least one camera and the at least one sensor. The at least one processor may be configured to acquire information about head pose and head-based gaze direction of a user, based on data input from the at least one sensor and multiple key points input from the at least one camera according to recognizing rotation of a user's head, estimate gaze lines of the user, based on the acquired information about head pose and head-based gaze direction, and estimate a distance to a target point, based on the gaze lines of the user, according to identifying that vestibulo-ocular reflex is activated based on the gaze lines of the user.

    Abstract: Provided are an electronic device for sharpening an image and an operation method thereof. A method, performed by the electronic device, of sharpening an image includes: obtaining an image generated by a camera of the electronic device; obtaining a first sharpening kernel for enhancing sharpness of the image, wherein the first sharpening kernel is data including a plurality of weights to be applied to pixels in the image, the data being of a lower resolution than the image; determining coordinates corresponding to some weights indicating representative values of the first sharpening kernel from among the plurality of weights in the first sharpening kernel; generating a second sharpening kernel by selecting the weights corresponding to the determined coordinates; and obtaining a sharpened image by applying the second sharpening kernel to the image.

    Abstract: Various embodiments of the disclosure relate to devices and methods for user authentication on an electronic device. The electronic device comprises a plurality of lighting devices, a camera, a display, and a processor. The processor is configured to display an object on the display, obtain, through the camera, a plurality of images based on an image obtaining pattern randomly generated, obtain biometric information using at least one of the plurality of images, obtain information about a variation in a user's gaze corresponding to a movement of the object displayed on the display using the plurality of images, and perform authentication on the user based on the biometric information and the user gaze variation information. Other embodiments are available as well.
