  • Data processing apparatus, data processing method and data processing program, encoding apparatus, encoding method and encoding program, and decoding apparatus, decoding method and decoding program
    Patent number: 8204326
    Abstract: A data processing apparatus includes a motion vector storage unit, an index value generating unit, a storage control unit, and a motion vector reading unit. The motion vector storage unit stores a motion vector in a unit block area. The index value generating unit generates the index value corresponding to a position of the unit block at upper left and upper right corners of an object block for which a prediction motion vector is to be acquired, on the basis of a size of the object block. The storage control unit copies a motion vector of an adjacent block by each of the unit block area and stores the copied motion vector. The motion vector reading unit obtains the index value indicating the unit block area on the basis of the index value. The prediction motion vector is obtained on the basis of the motion vector.
