According to one embodiment, provided is a method by which an electronic device comprising a minimum fingerprint sensing area processes fingerprint information, comprising the steps of: acquiring a fingerprint image from the fingerprint sensing area; calculating a shade change value, defined by a shade difference value from a neighboring pixel, for each pixel of the fingerprint image; selecting points, as feature point candidates, of which the shade change value is a threshold value or more; applying artificial distortion for noise filtering to an area including the feature point candidates and neighboring pixels thereof; and selecting, as final feature points, candidates of which the shade change value after the artificial distortion is within a threshold range from among the feature point candidates.

Electronic device comprising minimum sensing area and fingerprint information processing method thereof

An application-executing method using fingerprint recognition includes obtaining an image of a first fingerprint through a fingerprint sensor and recognizing the first fingerprint, executing a first application corresponding to the first fingerprint in a first screen when the first fingerprint is recognized, obtaining an image of a second fingerprint through the fingerprint sensor and recognizing the second fingerprint, determining whether the second fingerprint is recognized within a predetermined time after the first application is executed, and, based on a determination result, when it is determined that the second fingerprint is recognized within the predetermined time after the first application is executed, generating a second screen by splitting the first screen, and executing the first application on one of the second screen, and a second application corresponding to the second fingerprint on the other of the second screen.

Application executing method using fingerprint recognition, device therefor, and computer readable recording medium therefor

Disclosed herein is a light guide panel for a backlight unit of a liquid crystal display (LCD). The light guide panel enables adjustment in viewing angle and brightness at a specific position and angle by controlling a cross-sectional shape of front prisms of the light guide panel.

A method and an apparatus for acquisition of calibrated three dimensional data from camera image. The apparatus for acquisition of calibrated three dimensional data from camera image includes a cameral, alight source and an image processing computer. The camera acquires a light strip image of a target object. The light illuminates light strip to the target object and provides information about the illumination angle form base line (or reference line). The image processing computer obtains image and information about the angle .theta. of light plane from base line; computes connection strength of neural network and acquires calibrated three dimensional data in neutral network based on the obtained information. The mapping relationship between a control point in the three-dimensional space and a control point projected onto the two-dimensional image plane and illumination angle of light source to control point are derived by the neural network circuit.
