    Abstract: PURPOSE: An image encoding/decoding method and device thereof are provided to improve image encoding performance by adaptively allocating a codeword about a syntax element in an image encoding environment having various resolutions and a picture quality. CONSTITUTION: An image encoding device(110) includes a characteristic analyzing unit(111), a codeword allocating unit(112), and an encoding unit(113). The characteristic analyzing unit analyzes a characteristic of encoding data which encoded characteristic of an input image and the input image. The codeword allocating unit allocates a codeword to a syntax element of the input image according to a characteristic of the encoding data. The encoding unit generates a bit stream by encoding the input image by the codeword.

    Abstract: PURPOSE: A method and apparatus for video encoding/decoding using an adaptive codeword assignment to syntax elements are provided to enhance encoding performance under an image encoding environment having various encoding bit rates and various image sizes. CONSTITUTION: A feature analysis unit(111) analyzes the features of encoding data obtained from an input image, and a codeword assignment unit(112) allocates a codeword to a symbol value of a syntax element when using the input image. An encoding unit(113) encodes the syntax elements in the codeword to generate a bit stream.
