  • Patent number: 10218991
    Abstract: Encoded data is decoded based on tile data division information, tile data position information, block line data division information, and block line data position information. The tile data division information indicates whether the encoded data is composed of tile data items that serve as encoded data items of tiles. The tile data position information indicates positions of the tile data items. The block line data division information indicates whether each tile data item is composed of first block line data and second block line data. The first block line data serves as encoded data of a first block line that is a set of blocks arranged linearly. The second block line data serves as encoded data of a second block line next to the first block line. The block line data position information indicates a position of the second block line data.

  • Patent number: 10123021
    Abstract: An amount of code is reduced for blocks in which visible degradation is not easily susceptible, while a large amount of code is assigned to blocks whose degradation in image quality is easily perceptible thereby suppressing the number of blocks for which a process is performed to achieve high quality image and thus suppressing an increase in the total amount of code. An input image is encoded in units of blocks. A block evaluation value for the block is calculated. The block is divided into N sub-blocks where N is equal to or greater than 2, and a sub-block evaluation value is calculated for each sub-block. A quantization parameter for the block is controlled based on the block evaluation value and the sub-block evaluation values.
