Abstract

The present invention relates to an encoding method and an encoding device. The encoding method comprises acquiring a plurality of code stream components of a to-be-encoded image, each of the plurality of code stream components comprising a code stream of a transform coefficient of the to-be-encoded image; and storing the plurality of code stream components according to the type sequence of the transformation coefficients. According to the scheme provided by the embodiment of the invention, the plurality of code stream components of the to-be-coded image are stored according to the type sequence of the transformation coefficients, so that the code stream carrying frequency can be reduced in the coding process, and further, the coding efficiency can be improved.

Description

technical field [0001] The present application relates to the field of encoding and decoding, and more specifically, relates to an encoding method and an encoding device. Background technique [0002] Joint Photographic Experts Group Extended Range (JPEG XR) is a continuous-tone still image compression algorithm and file format. [0003] The JPEG XR code stream structure can be composed of tagged image file format (Tagged Image File Format, TIFF) encapsulation information, image header (Image_header) information, index table (Index_table) and the code stream of each tile. In the frequency mode, the code stream of each macroblock in the tile can be divided into DC coefficient (Direct Current Coefficient, DCCoefficient), low pass coefficient (Low Pass Coefficient, LP Coefficient), high pass coefficient (High Pass Coefficient, HP Coefficient) and variable Truncation coefficients (FLEX coefficients) are stored independently. [0004] However, in the process of entropy encoding...
