摘要： The present invention relates to an image encoding/decoding method using block transform and an apparatus thereof and provides an image encoding apparatus. In the image encoding apparatus, each pixel in the current block of an image is encoded before the current block is encoded. The image encoding apparatus encodes an image by using and predicting at least one pixel adjacent to each pixel in a determined prediction direction, wherein the current block has L X M dimensions and the L value is not equal to the M value. According to the invention, the pixels in the block can be predicted from the most adjacent pixel in a spatial prediction direction. Therefore, compression efficiency can be improved by increasing the prediction accuracy of the blocks. In addition, an image can be encoded and decoded efficiently through improvement of the compression efficiency.

摘要： The present invention relates to a method for encoding/decoding a motion vector and an apparatus thereof, and comprises the steps of: selecting a candidate motion vector set for a current motion vector, selecting a prediction motion vector from the candidate motion vector set, and judging whether or not the prediction motion vector is predictable in a decoding apparatus. If the prediction motion vector is predictable, the current motion vector is encoded using a motion vector prediction mode that indicates a prediction motion vector and a prediction possibility. If the prediction motion vector is not predictable, the current vector is encoded using a motion vector prediction mode that indicates a default prediction motion vector and a prediction impossibility. According to the invention, the method and the apparatus can provide information for searching for the prediction motion vector and share a certain function for the search without directly notifying the prediction motion vector for the current motion vector to the decoding apparatus so that the current motion vector may be encoded and/or decoded by selecting the prediction motion vector according to the motion vector prediction mode, and the motion vector prediction mode may be transmitted to the decoding apparatus. Therefore, the amount of encoded bits can be reduced and the performances of the motion vector prediction and compensation can be improved.
