Abstract:
Provided is an apparatus and method for generating a hologram pattern with a reduced amount of computation. The apparatus may include a reference depth layer setting unit configured or having a capacity to set a reference depth layer using data associated with a three-dimensional (3D) object, a first hologram pattern generating unit configured to generate a first hologram pattern corresponding to the 3D object in the reference depth layer, and a second hologram pattern generating unit configured to generate a second hologram pattern in a hologram plane using the first hologram pattern.
Abstract:
An image processing apparatus that configures a single frame by determining a central image of a certain viewpoint as an original resolution, and frame another single frame by combining a left image of a left viewpoint and a right image of a right viewpoint. The image processing apparatus may generate three-dimensional (3D) image data configured using the frames, and may encode, decode, and render an image based on the 3D image data.
Abstract:
A display apparatus and method that reduces block noise by performing block noise boundary detections and generating a block noise boundary map on the basis of a result of the detections to cope with local random block noise having irregular shaped and blurred block boundaries to perform adaptive deblocking filtering. The apparatus includes: an image receiver; a map generator to generate a block boundary map by performing convolution using a plurality of kernels on a received image; a determiner to determine a filter parameter on the basis of the block boundary map and a block boundary period included in the block boundary map; a deblocking filter to vary a filter strength on the basis of the determined filter parameter; and a display on which an image in which block noise is removed by the deblocking filter is displayed.
