    • 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.

    • A deblocking filtering method for image data and a deblocking filter. According to the deblocking filtering method for image data and the deblocking filter, when computation of Boundary Strength (BS) values for each boundary based on one of horizontal and vertical directions from input image data is completed, it is possible to estimate BS values for each boundary based on a direction different from the currently selected direction by using the computed BS values. Further, deblocking filtering is performed based on corresponding directions according to the estimated values, so that the deblocking filtering can be completely performed with only a BS value of boundaries based on a selected one direction. Consequently, a BS value computation process necessarily required in a deblocking filtering process can be considerably reduced, and thus time required in the operation process of a deblocking filter can also be considerably reduced.
