    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.
