    摘要： A method and apparatus for encoding/decoding an image by using an extended skip mode are provided. The method includes setting a backward reference block motion vector with respect to an adjacent block of a current block as a predictive motion vector of the current block or determining a predictive motion vector from a forward reference block motion vector with respect to a block located in a backward reference picture at the same position as the current block, performing motion compensation by using the predictive motion vector, and setting a prediction mode when the motion compensation results in satisfaction of an optimal skip condition.

    摘要： The present disclosure relates to encoding and decoding apparatus and method using intra prediction. The encoding apparatus includes a reference pixel characteristics extractor for receiving reference pixel(s) included in neighboring blocks of a target block to encode to determine a reference pixel characteristic and determining whether adaptive filtering is applied to the reference pixel(s), based on reference pixel characteristic; a first intra predictor responsive to when the adaptive filtering is determined by the reference pixel characteristics extractor to be applied for comparing between results of performing intra prediction using high-frequency filtered reference pixel and intra prediction using high-frequency-unfiltered reference pixel to output the cost-efficient result along with filtering information indicating whether to perform filtering; and a second intra predictor for outputting the result of performing the intra prediction using the high-frequency-unfiltered reference pixel when the reference pixel characteristics extractor determines that the adaptive filtering is not to be applied.
