Patent Searching and Data


Title:
TERMINAL AND DATA MANAGEMENT DEVICE
Document Type and Number:
Japanese Patent JP2016005211
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To enhance coding efficiency, by reducing the amount of codes of a block shift vector indicating the position of a reference block.SOLUTION: A terminal is constituted to includes a coding section for searching a motion vector by comparing a coded block and a local decoded image, when generating the prediction image of the coded block, for the data processed by an arithmetic processing section, searching a reference block corresponding to the coded block among an already decoded region in the same picture of the local decoded image, and outputting a block shift vector indicating the position of the reference block, performing variable length coding of the motion vector or the block shift vector, and performing variable length coding of the block shift vector by using a coding system different from that used for variable length coding of the motion vector.
