The encoding apparatus selects an intra prediction mode of current block to encode from input video by a variation of the value of pixel adjacent to the current block; encodes a residual block from intra-predicting the current block in the selected intra prediction mode of current block to generate coded coefficient bit having a bitstream generator for generating and outputting a bitstream including the coded coefficient bit and a prediction mode bit representing the selected intra prediction mode of current block by a macroblock or subblock unit with the prediction mode bit included selectively in the bitstream depending on the variation. Accordingly, selection process of a prediction mode for image compression is simplified, a faster compression is obtained and compressed data is deflated to improve compression efficiency."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for selecting a prediction mode, and image encoding/decoding method and apparatus using same","description":"The present disclosure concerns a method and apparatus for selecting an intra prediction mode and a video encoding/decoding method and apparatus using same.
