Abstract:
Provided is an image restoration method of restoring an image obtained through an array camera, the image restoration method including obtaining a plurality of images through lens elements included in the array camera, obtaining a global parameter of the plurality of images, generating first processed images by transforming a viewpoint of each of the plurality of images based on the obtained global parameter, obtaining a local parameter for each pixel corresponding to each of the first processed images, generating second processed images by transforming the first processed images based on the obtained local parameter, and generating a synthesized image of a target viewpoint based on synthesizing the second processed images.
Abstract:
A method and apparatus for outputting a three-dimensional (3D) image are provided. To output a 3D image, a stereo image is generated based on viewpoints of a user and rendered into a 3D image. Since the stereo image is generated based on the viewpoints of the user, the user views a different side of an object appearing in the 3D image depending on a viewpoint of the user.
Abstract:
A three-dimensional (3D) image rendering method and an apparatus are provided. The 3D image rendering method includes determining intersection points between candidate rays and an optical layer based on a first refractive index of a first medium that is disposed between a display panel and the optical layer and a second refractive index of a second medium that is outside a 3D display apparatus, and assigning a pixel value to a pixel of the display panel based on respective distances between the intersection points and optical elements of the optical layer.
Abstract:
A display apparatus providing a multi-view image is provided, which may include a panel unit to provide light through a plurality of pixels corresponding respectively to a plurality of viewpoints, and an optical unit to provide the light to a left eye position and a right eye position at a pre-designated viewing distance, respectively, wherein the optical unit may be configured for light from pixels for view images having discontinuous viewing indices, among the plurality of pixels, to be transferred to the left eye position and the right eye position.
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.
Abstract:
A method and apparatus for generating a hologram pattern using depth quantization may generate a hologram pattern corresponding to a three-dimensional (3D) object in a hologram plane using color image information of the 3D object and a point of the 3D object included in a quantized depth layer.
Abstract:
