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.

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.

摘要： A method and apparatus for estimating the contour of a user object in a moving picture during video communications so that a personal background image is not provided during video communications. Information about center coordinates as well as a size of a face of the user object is extracted from a moving picture frame. Edges are extracted from the moving picture frame, and a boundary of a head of the user object is estimated using a semicircle. The boundaries of left and right shoulders and left and right arms of the user object are estimated using second-order function graphs that overlap a largest portion of the edges. An entire contour of the user object is estimated according to the boundaries of the head, the left and right shoulders, and the left and right arms of the user object.

The decoder comprises a plurality of operation units that successively perform a Variable Length Decoding (VLD) operation, an Inverse Transform & DeQuantization (ITDQ) operation, and an intra PREDiction & inter PREDiction (PRED) operation with respect to a macroblock for which each operation unit is to perform a decoding operation, on receiving information on a macroblock, for which each operation unit is to carry out the decoding operation, with reference to a synchronization information storage unit. When the VLD, ITDQ, and PRED operations have been completed with respect to all macroblocks, the synchronization information storage unit is initialized, and the multiple operation units perform Deblocking Filter (DF) operations with respect to macroblocks for which the operation units are to carry out the DF operations respectively, and then, complete decoding of compressed image data currently received.
