Abstract:
A three-dimensional (3D) display method includes generating N first visual images, N being a natural number greater than 1; generating M second visual images from each of the N first visual images, M being a natural number greater than 1; acquiring N visual image groups corresponding to the N first visual images, respectively, such that, for each one of the N visual image groups, the visual image group includes the M second visual images generated from the first visual image, from among the N first visual images, to which the visual image group corresponds; generating M elemental image array (EIA) images based on the N visual image groups; and time-share displaying the M EIA images.
Abstract:
An integrated image display, a method for operating the display, and a system including the display are provided. The integrated image display includes: a display panel including pixels; and a first lens array including a plurality of lenses, wherein each of the plurality of lenses is capable of displaying, in a beam direction, a subset of a plurality of subpixels included in at least one pixel from among the included pixels.
Abstract:
A method for reducing a moire fringe includes calculating a moire fringe width for each of different angles between a microlens array and pixels of a display screen. The method includes determining, to be a final inclination angle between the microlens array and the pixels of the display screen, one of the different inclination angles that corresponds to a minimum width among the calculated moire fringe widths.
Abstract:
A method of determining eye position information includes identifying an eye area in a facial image; verifying a two-dimensional (2D) feature in the eye area; and performing a determination operation including, determining a three-dimensional (3D) target model based on the 2D feature; and determining 3D position information based on the 3D target model.
Abstract:
An image processing method and apparatus are provided. The image processing method may include determining whether stereoscopic objects that are included in an image pair and that correspond to each other are aligned on the same horizontal line. The method includes determining whether the image pair includes target objects having different geometric features from those of the stereoscopic objects if the stereoscopic objects are not aligned on the same horizontal line. The method includes performing image processing differently for the stereoscopic objects and for the target objects if the image pair includes the target objects.
Abstract:
A three-dimensional (3D) display apparatus and method are provided. The 3D display apparatus may include a display screen configured to display each of a plurality of sub-images included in a single frame of a 3D image using a time-division multiplexing (TDM), a polarizer configured to polarize each of the displayed sub-images by changing a polarization direction using the TDM, in synchronization with the display screen, and microlens arrays arranged in a plurality of layers and configured to sequentially refract the polarized sub-images, respectively.
Abstract:
A display device may include a plurality of display panels, and light path adjusters disposed on upper portions of the plurality of the display panels. The light path adjusters include a lens array configured to transfer different beams emitted from the plurality of display panels to each eye of a user, and a joint removal structure disposed on one side of the light path adjusters corresponding to a connecting joint that connects the plurality of display panels. The joint removal structure is configured to refract the beams emitted from the plurality of display panels.
Abstract:
A method and apparatus for tracking an object, and a method and apparatus for calculating object pose information are provided. The method of tracking the object obtains object feature point candidates by using a difference between pixel values of neighboring frames. A template matching process is performed in a predetermined region having the object feature point candidates as the center. Accordingly, it is possible to reduce a processing time needed for the template matching process. The method of tracking the object is robust in terms of sudden changes in lighting and partial occlusion. In addition, it is possible to track the object in real time. In addition, since the pose of the object, the pattern of the object, and the occlusion of the object are determined, detailed information on action patterns of the object can be obtained in real time.
