摘要： 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.

摘要： 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.

摘要： 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.
