Abstract:
A display device is provided. The display device includes a plurality of diffractive optical elements each configured to emit light guided in a light guide plate to a user. Virtual images by the light are observed by the user at two or more different depths according to the plurality diffractive elements.
Abstract:
A three-dimensional (3D) image rendering method and an apparatus are provided. The 3D image rendering method includes determining optical images associated with candidate viewpoint positions in a viewing zone, determining virtual rays intersecting a pixel of a display panel based on the determined optical images, and assigning a pixel value to the pixel based on respective distances between intersection points between the rays and an optical layer and optical elements of the optical layer.
Abstract:
An object tracking method and apparatus based on object verification are provided. The object tracking method includes detecting a first area that corresponds to a target object in a current frame, aligning the target object with respect to the current frame, and tracking the target object in a next frame based on whether a second area corresponds to the target object as a result of the alignment.
Abstract:
An image device generates a plurality of multi-view output images on the basis of an input image, and outputs the plurality of generated output images. The plurality of output images are outputted in a direction opposite to the views of the output images. The plurality of outputted output images are projected towards a left eye and a right eye of a viewer of the image device such that the viewer can recognize three-dimensional images.
Abstract:
A computing apparatus for providing a three-dimensional (3D) interactive user experience (UX) is provided. The computing apparatus may include an object position estimator configured to calculate first coordinates recognized by a user as a position of a first point of an object in a stereoscopic image. The computing apparatus may include a pointing determiner configured to determine whether the user points to the first point based on the first coordinates and second coordinates, the second coordinates representing a pointing position of the user.
Abstract:
A backlight unit includes first light guide plates (LGPs) provided in a line shape, and second LGPs provided in a line shape and disposed between the first LGPs. The backlight unit may include a controller configured to control a plurality of light sources to provide a light to the first LGPs when a three-dimensional (3D) image is displayed on a display panel that receives the light from at least one of the first LGPs and the second LGPs, and to provide the light to the first LGPs and the second LGPs when a two-dimensional (2D) image is displayed on the display panel.
Abstract:
A display device includes a backlight unit. The backlight unit may include a first light guide plate (LGP) comprising a first optical material and a second optical material. The first LGP is configured to emit light guided through the second optical material toward a display panel using the first optical material. The backlight unit may include a second LGP disposed between the first LGP and the display panel. The second LGP is configured to emit light toward the display panel using a diffuser plate provided in a lower portion of the second LGP. The backlight unit may include light sources configured to provide, under control of a controller, light to the first LGP if a three-dimensional (3D) image is displayed on the display panel, and to provide light to the second LGP if a two-dimensional (2D) image is displayed on the display panel.
Abstract:
An apparatus for generating a hologram that may generate a three-dimensional (3D) hologram pattern at a high speed may include a pattern setting unit to set points for which hologram patterns are to be generated with respect to a one-eighth area of an entire area for which a hologram pattern is to be generated, a calculation unit to calculate pattern values for a plurality of reference points selected with respect to the one-eighth area of the entire area, and to generate a pattern for the one-eighth area using recurrent interpolation, and a pattern duplicating unit to complete a pattern for the entire area by duplicating the generated pattern for the one-eighth area.
Abstract:
A method and apparatus for generating coherent light, and a display apparatus using coherent light are provided. A wide-angle coherent light generation apparatus may focus parallel light onto a focal point, and may generate coherent light at a wide angle, using an optical device.
