Abstract: A hierarchical motion prediction apparatus and method. The hierarchical motion prediction method splits a current frame and a reference frame into pixel groups, changes a pixel location of each pixel group, and selects one pixel, and thus resolutions of the current frame and reference frame are reduced. A motion vector of a down-sampled current block is obtained based on a down-sampled current frame and reference frame, and is expanded to a motion vector of an original resolution based on a down sampling rate.

Abstract: A display apparatus is provided. The display apparatus includes an input interface, a first storage, a display, and a processor. Pixel values corresponding to a predetermined number of lines in an image input through the input interface are stored in the first storage,. The processor acquires a first patch of a predetermined size by sampling a number of pixel values located in an outer region of a matrix centering about a specific pixel value from among the pixel values stored in the first storage, acquires a high-frequency component for the specific pixel value based on the acquired first patch, and processes the input image based on the high-frequency component. The display displays the processed image.

Abstract: A motion vector estimation method of a motion vector estimation apparatus are provided. The motion vector estimation method of the motion vector estimation apparatus includes: determining a motion vector of a current block by setting, in another frame, a local search area for searching a plurality of reference pixel blocks corresponding to the current block which is one of pixel blocks in a single frame; and finally determining one of the determined motion vector and a previous motion vector referred to in order to determine the local search area as a motion vector of the current block, based on sum of absolution difference (SAD) values of the reference pixel blocks included in the local search area.
