    摘要： To provide an image decoding method allowing decoding of a multiview video even when no prefix NAL units are used. The image decoding method includes: parsing NAL units of a base view; decoding an image of the base view; parsing MVC extension parameters of a non-base view; searching whether or not prefix NAL units for a base view are present; either computing MVC extension parameters for the base view when no prefix NAL units are present or parsing the MVC extension parameters of the base view when prefix NAL units for the base view are present; and decoding the non-base view using the MVC extension parameters of the base view and the MVC extension parameters of the non-base view.

    摘要： The present invention provides a video coding method and a video decoding method which allow enhancement of coding efficiency and improvement in video quality. A video coding apparatus includes: a mode determination unit which determines a notification method for notifying a transform block size to be used in orthogonal transform of a current block to be either the implicit mode or the explicit mode, and outputs the ABT mode indicating the determined notification method; an orthogonal transformation unit which transforms the difference values between the input image and predicted image into frequency coefficients based on the transform block size determined in accordance with the determined notification method; a quantization unit which quantizes the frequency coefficients and output the quantized values; and a variable length coding unit which performs variable length coding on the quantized values, the ABT mode, and the like, so as to output a coded stream.

    摘要： A decoding method according to the present invention is a method of decoding a variable length code to a Run symbol and a Level symbol. The Run symbol indicates the number of consecutive coefficients each having a value of zero. The Level symbol indicates a value of a non-zero coefficient following the Run symbol. The decoding method includes decoding a variable length code to a code number, determining whether the code number obtained in the decoding belongs to a first range or a predetermined range, decoding the code number to a Run symbol and a Level symbol by referring to a table, when it is determined that the code number belongs to the first range, and decoding the code number to a Level symbol and then decoding a variable length code following the decoded variable length code to a Run symbol, without referring to the table, when it is determined that the code number belongs to the predetermined range.
