20140146181 | APPARATUS AND METHOD FOR ACQUIRING DIFFERENTIAL IMAGE - An apparatus for acquiring a differential image includes: an image acquiring unit acquiring a first image including environment light from an image sensor of a camera and infrared polarized light from an illuminating unit and a second image including horizontal polarized light of the environment light; an image correcting unit correcting brightnesses of background areas of the first and second images; and a differential image generating unit generating a differential image between the first and second images of which the brightnesses of the background areas are corrected. | 05-29-2014 |
20140147002 | USER AUTHENTICATION APPARATUS AND METHOD USING MOVEMENT OF PUPIL - A user authentication apparatus and method using movement of a pupil is capable of rapidly and accurately performing authentication with high security by storing the respective frequencies of objects mechanically moving on a screen and security keys corresponding thereto, comparing a frequency detected from movement of a pupil gazing at any object with a frequency of the object, and performing the authentication based on a corresponding security key when the detected frequency is included in a predetermined range. | 05-29-2014 |
20140160005 | APPARATUS AND METHOD FOR CONTROLLING GAZE TRACKING - An apparatus and a method that controls gaze tracking. The apparatus includes an imaging device that has an image sensor divided into a plurality of zones and a gaze tracking controller. The gaze tracking controller is configured to determine a lens PSF and an image sensor PSF of the camera, respectively, using images for each zone acquired from image elements disposed in each zone of the image sensor. In addition, the gaze tracking controller is configured to estimate illumination reflection points using an imaging device PSF determined from the determined lens and image sensor PSFs at the time of detecting a user gaze using the imaging device. | 06-12-2014 |
20140160011 | APPARATUS AND METHOD FOR CHECKING GAZE OBJECT - An apparatus for checking a gaze object includes an eye detector configured to detect eyes from a captured image of a user who stares at objects while the objects displayed on a display move at certain frequencies, a frequency converter configured to check a motion of the detected eyes and convert the motion of the eyes into an eye moving frequency, and a discriminating unit configured to compare the eye moving frequency and moving frequencies of the objects and discriminate an object at which the user stares depending upon whether or not the eye moving frequency is identical with the moving frequencies of the objects. | 06-12-2014 |
20140160249 | DISPLAY SYSTEM AND METHOD - A display system includes a line-of-sight tracking camera to detect an eyeball of a driver, first and second stereo cameras, a controlling unit, and a storing unit. The first and second stereo camera photographs a range corresponding to a field-of-view based on stereo camera-based line-of-sight information that is changed based on line-of-sight tracking camera-based line-of-sight information, and provide a photographed image. The controlling unit converts the line-of-sight tracking camera-based line-of-sight information into first and second stereo camera-based line-of-sight information based on pre-stored position and rotation information of the tracking camera and the first and second stereo cameras, and project the converted information onto the first and second stereo cameras, such that a three-dimensional line-of-sight coordinate is calculated. The storing unit stores information related to a system as well as the position and rotation information of the tracking camera and the first and second stereo cameras. | 06-12-2014 |
20140172580 | SYSTEM AND METHOD FOR PROVIDING INFORMATION ON ADVERTISED GOODS - A system for providing information on an advertised product includes an advertised product information processing unit for comparing a dominant frequency of the advertised product with user's eyes movement frequency, and, if the frequencies coincide with each other, determining that the user is gazing at the advertised product, extracting information on the advertised product from a storage unit and outputting the extracted information through an output unit. | 06-19-2014 |
20140232746 | THREE DIMENSIONAL AUGMENTED REALITY DISPLAY APPARATUS AND METHOD USING EYE TRACKING - A three-dimensional augmented reality display apparatus and method using eye tracking adjust a depth of an image without an increase in volume and are easily applied to an augmented reality head up display (HUD), by adjusting an angle of a total reflection prism based on positions of both eyes of a driver detected in real time using eye tracking to allow a right eye image to be formed in a driver's right eye and allow a left eye image to be formed in a driver's left eye. | 08-21-2014 |
20150178887 | DISPLAY CONTROL APPARATUS AND CONTROL METHOD FOR VEHICLE - A display control apparatus of a vehicle for controlling a graphical user interface on a screen of a display apparatus which is mounted to a vehicle is provided. The display control apparatus includes a time information detector configured to detect time information for determining the height of the sun. A driving information detector is configured to detect driving information for determining a driving direction of the vehicle. A controller is configured to receive the time information from the time information detector and the driving information detected from the driving information detector so as to reposition a graphical user interface area where the graphical user interface is displayed on the screen. The graphical user interface area may be repositioned so as to escape from a reflection area where sunlight is reflected by the screen. | 06-25-2015 |
