    Abstract: An image encoding method comprises an encoding step (S801) for encoding first binarized data, which indicates a first intra prediction mode, and second binarized data, which indicates a second intra prediction mode. The encoding step (S801) uses a context adaptive arithmetic encoding to encode a first context adaptive portion, which is a portion of the first binarized data, and a second context adaptive portion, which is a portion of the second binarized data, and further uses a bypass encoding to encode a first bypass portion, which is another portion of the first binarized data, and a second bypass portion, which is another portion of the second binarized data, thereby generating encoded data that includes the first and second context adaptive portions and that also includes the first and second bypass portions following the first and second context adaptive portions.

    Abstract: An image encoding method comprising an addition step (S701) for adding a first adjacent motion vector as a prediction motion vector candidate to a candidate list of prediction motion vectors for use in the encryption of the current motion vector, a selection step (S702) for selecting a prediction motion vector from the candidate list, and an encoding step (S703) for encoding the current motion vector using the prediction motion vector, wherein during the addition step (S701), the first adjacent motion vector, which designates a position within a first reference picture included in a first reference picture list, is added to the candidate list for the current motion vector, which designates a position within a second reference picture included in a second reference picture list.

    IPC: H04N7/26

    Abstract: An image decoding method according to one embodiment of the present invention comprises: a context control step (S204) in which a context to be used for a block to be processed is determined from a plurality of contexts; and an arithmetic decoding step (S210) in which the determined context is used to arithmetically decode a bit string corresponding to the block to be processed. In the context control step (S204), if the signal classification of a control parameter is a first type, the context is selected using a condition whereby the control parameters of the left-side adjacent block and upper adjacent block of the block to be processed are employed (S206), and if the signal classification of the control parameter is a second type, the context is determined using a condition whereby the control parameter of the upper block is not employed (S207). The second type is "cbf_luma", "cbf_cb", or "cbf_cr".
