    摘要: The present invention relates to a method for multiplexing an optimal 3D image, by detecting inhomogeneity and alignment error of lens in a lenticular 3D LCD monitor, minimizing the image distortion caused by the detected error, and considering the viewer's position.Thus, the method in accordance with the present invention is characterized by supplementing the mapping table for compensating the image distortion to the mapping table representing the relationship between N original view images and a multi-view image multiplexed to a 3D image. Thus, the present invention discloses a method for detecting the alignment error and inhomogeneity of lens by predicting the alignment error and inhomogeneity of lens in 3D monitor using intentionally generated test images, calculating the image index difference between the sub-pixel having to be originally observed from a viewer's eyes and the practically observed image pixel. Moreover, the present invention discloses a method for compensating the distance of a viewer by calculating the index difference between the sub-pixel having to be observed by the viewer located at optimal viewing position and the sub-pixel observed at the practical viewer's position, in the method for compensating the image distortion according to a viewer's position.

    摘要: A method for estimating a motion vector in a moving picture is disclosed, that selectively uses a bilinear interpolation to estimate a motion vector, which reduces a computational complexity. The method includes estimating Y component motions of all macroblocks and determining a coding prediction mode when a motion vector is obtained. Then, blocks for which the coding prediction mode is determined to be INTER mode are searched for halfpels. A vector having a smaller SAD to an 8×8 block in question from motion vectors (MVibil) obtained by a bilinear interpolation of a 16×16 block motion vector(MV6) and motion vectors of blocks around the 16×16 block is selected as an initial motion vector. A local search of the initial motion vectors of the 8×8 blocks in a ±2 search region is made when the initial vectors of the 8×8 block are determined. Then, a ±0.5 halfpel search is again made to obtain final motion vectors. The final motion vectors are used either in predicting a motion in 8×8 block units or in predicting a motion in 16×16 block units.

    摘要: A method of coding a moving picture is provided that reduces blocking artifacts. The method can include defining a plurality of defining pixels S0, S1, and S2, which are centered around a block boundary. If a default mode is selected then frequency information of the surroundings of the block boundary is obtained. A magnitude of a discontinuous component in a frequency domain belonging to the block boundary is adjusted based on a magnitude of a corresponding discontinuous component selected from a pixel contained entirely within a block adjacent the block boundary. The frequency domain adjustment is then applied to a spatial domain. Or, a DC offset mode can be selected to reduce blocking artifacts in smooth regions where there is little motion.
