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 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.
