  • Publication number: 20170324970
    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: 9210433
    Abstract: A specific region in each frame image input after a detection process has been completed a predetermined number of times or more is estimated from a specific region detected from a past frame before the frame. The shift between the specific region detected from a first frame image input after the detection process has been completed the predetermined number of times or more and the specific region estimated for the first frame image is obtained. When the shift falls within a predetermined range, an encoding parameter to encode the specific region estimated for a second frame image input at a point the detection process for the first frame image has been completed with a higher image quality than that of regions other than the specific region is set.
