    摘要： Disclosed is video encoding technology, and more particularly a method for searching for a motion vector in a procedure of estimating a motion in video frames. The motion vector search method includes the steps of: individually calculating error energies of a center point and vertices of a search pattern in a search window used in a previous frame with respect to a center of the search window established in the current frame, thereby designating a motion vector candidate point; either determining the motion vector candidate point as a moving point of a motion vector, or calculating error energies of a pair of neighboring points and re-establishing a motion vector candidate point; and either determining the re-established motion vector candidate point as a moving point of a motion vector, or re-establishing a search pattern, re-checking the error energies of the center point, the vertices and the neighboring points, and determining a moving point of a motion vector.

    摘要： A motion search method and apparatus for minimizing an off-chip memory access to reduce cycles for predicting a motion vector. A sum of absolute differences (SAD) calculation processing is performed, while an off-chip memory is accessed using Direct Memory Access (DMA). A position of a current macro block is determined if a frame is input and the length of a horizontal search line is set according to adjacent motion vectors and predetermined external parameters. The SADs are calculated by calculating medians of the adjacent motion vectors as a predictive motion vector, setting a vertical direction value of the predictive motion vector as an initial search line, and sequentially searching at least one horizontal search line, and determining a position of a minimum SAD from the at least one horizontal search line. The minimum SAD position is selected as a final motion vector.

    摘要： A method and apparatus for generating a thumbnail image are provided so that the out-of-focus (OOF) information can be ascertained from looking at the thumbnail. An input image is decoded, and a degree of the amount of OOF of the decoded image is measured (OOF information). There is a determination as to whether or not there is an EXchangeable Image File (EXIF) information about the input image. In the presence of EXIF information, a thumbnail image is extracted from the EXIF information and as much an OOF effect is applied to the thumbnail image in accordance with the degree of OOF. In the absence of the EXIF information, a thumbnail image is generated by scaling down the decoded image at a down scaler and applying as much of an OOF effect is applied to the thumbnail image in accordance with the degree of OOF.
