Abstract: An image coding method includes: deriving a candidate for a motion vector of a current block from a co-located motion vector; adding the candidate to a list; selecting the motion vector of the current block from the list; and coding the current block, wherein the deriving includes: deriving the candidate by a first derivation scheme in the case of determining that each of a current reference picture and a co-located reference picture is a long-term reference picture; and deriving the candidate by a second derivation scheme in the case of determining that each of the current reference picture and the co-located reference picture is a short-term reference picture.

Abstract: An image coding method includes: writing, into a sequence parameter set, buffer description defining information for defining a plurality of buffer descriptions; writing, into the sequence parameter set, reference list description defining information for defining a plurality of reference list descriptions corresponding to the buffer descriptions; and writing, into a first header of each processing unit which is included in a coded bitstream, buffer description selecting information for specifying a selected buffer description.

Abstract: A moving picture coding includes: coding a first flag indicating whether or not temporal motion vector prediction is used; when the first flag indicates that the temporal motion vector prediction is used: coding a first parameter for calculating the temporal predictive motion vector; wherein when the first flag indicates that the temporal motion vector prediction is not used, the first parameter is not coded.

Abstract: An image decoding method includes: dividing a current block into sub-blocks; deriving, for each sub-block, one or more prediction information candidates; obtaining an index; and decoding the current block using the prediction information candidate selected by the index.

Abstract: An image coding method includes: performing context arithmetic coding to consecutively code (i) first information indicating whether or not to perform sample adaptive offset (SAO) processing for a first region of an image and (ii) second information indicating whether or not to use, in the SAO processing for the first region, information on SAO processing for a region other than the first region, the context arithmetic coding being arithmetic coding using a variable probability, the SAO processing being offset processing on a pixel value; and performing bypass arithmetic coding to code other information which is information on the SAO processing for the first region and different from the first information or the second information, after the first information and the second information are coded, the bypass arithmetic coding being arithmetic coding using a fixed probability.

Abstract: A processing system for processing information in a card having a plurality of functions, comprising a reading unit for reading information stored in a card therefrom, a plurality of processing units, each of which corresponds to one of the plurality of functions of the card, for processing the information read out by the reading unit in accordance with the respective functions, and an interlocking processing unit for interlocking at least two processing units which are included in the plurality of processing units when a card having a plurality of functions is supplied to the processing system.

Abstract: A POS system which readily allows introduction of a self-scanning function. The POS system includes a POS apparatus including a settlement terminal for effecting final settlement of the accounts for a purchased commodity or commodities, and one or a plurality of self-scanning registration terminals accommodated in the POS apparatus by way of a control apparatus and each including a commodity code reader for reading a commodity code applied to a commodity. The control apparatus communicates commodity purchase information based on commodity code information read by the commodity code reader of the self-scanning registration terminal or any of the self-scanning registration terminals between the self-scanning registration terminal and the POS apparatus. The POS system can be applied in the distribution industry, particularly in a store such as a mass sales store, a convenience store or a supermarket.
