    Abstract: A video processing method includes generating a first down-sampled block by down-sampling a first block included in a first frame; generating a plurality of second down-sampled blocks by down-sampling a second block included in a second frame; selecting one of the plurality of second down-sampled blocks by comparing the first down-sampled block and each of the plurality of second down-sampled blocks; and determining, based on the first down-sampled block and the one selected second down-sampled block, a motion vector whereby the second block points to the first block, wherein the plurality of second down-sampled blocks are generated using down-sampling methods that are different from each other with respect to samples of the second block.

    Abstract: Disclosed is a display apparatus including: a signal receiver configured to receive an image signal; a display configured to display an image; a processor configured to: calculate a change degree and a change direction of pixel value differences between at least one first pixel and two or more second pixels of an image, and change a pixel value of the first pixel based on the pixel value difference which is relatively small among the pixel value differences obtained by the calculated change degree and the calculated change direction.According to this, it is possible to enhance the image details without generating or and increasing of the noises.

    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.
