    Abstract: El método de decodificación de imágenes de una modalidad de la presente invención comprende: un paso de control de contexto (S204) para determinar el contexto que se utiliza para un bloque que es procesado, entre una pluralidad de contextos; y un paso de decodificación aritmética (S210) para utilizar el contexto determinado para decodificar aritméticamente una secuencia de bits que corresponde al bloque que es procesado. En el paso de control de contexto (S204), si un tipo de señal para parámetros de control es un primer tipo, el contexto se determina mediante el uso de una condición que utiliza parámetros de control para tanto un bloque izquierdo como un bloque superior, los cuales son adyacentes al bloque que es procesado (S206), y si el tipo de señal para los parámetros de control es un segundo tipo, el contexto se determina mediante el uso de una condición que no utiliza el parámetro de control para el bloque superior (S207).

    Abstract: A SPATIAL PREDICTION METHOD CAPABLE OF REDUCING THE COMPLEXITY OF SPATIAL PREDICTION INCLUDES: DETECTING AN EDGE (E) OVERLAPPING THE CURRENT BLOCK BY OBTAINING A HORIZONTAL GRADIENT (GY) AND A VERTICAL GRADIENT (GX) BETWEEN PIXELS WITHIN A BLOCK ADJACENT TO THE CURRENT BLOCK (S10); CALCULATING AN INTEGER SLOPE OF THE EDGE (S11); DETERMINING, FOR EACH PIXEL POSITION WITHIN THE CURRENT BLOCK, A SUB-PEL POSITION (450) BEING AN INTERSECTION BETWEEN (I) A LINE THAT HAS THE INTEGER SLOPE AND PASSES THROUGH THE PIXEL POSITION AND (II) A BOUNDARY OF THE ADJACENT BLOCK (S12); AND PREDICTING, FOR EACH PIXEL POSITION, A PIXEL VALUE AT THE PIXEL POSITION (440) BASED ON A PIXEL VALUE INTERPOLATED IN THE SUB-PEL POSITION (S13), WHEREIN THE BOUNDARY OF THE ADJACENT BLOCK IS A ROW OR A COLUMN THAT IS THE CLOSEST TO THE CURRENT BLOCK, AMONG ROWS OR COLUMNS OF PIXELS INCLUDED IN THE ADJACENT BLOCK.

    Abstract: Provided is an image encoding method that uses arithmetic encoding and that comprises the following: a first flag encoding step (S701) for arithmetically encoding a first flag (greater1_flag) indicating whether an absolute value of a processing-object coefficient included in the coefficient block of the processing object is greater than 1; and a second flag encoding step (S702) for arithmetically encoding a second flag (greater2_flag) indicating whether the absolute value of the processing-object coefficient is greater than 2. In the first flag encoding step and the second flag encoding step, it is determined whether there is a coefficient the absolute value of which exceeds a threshold in the coefficient block immediately prior to the coefficient block of the processing object (S711), and depending on the determination results, the context used in the arithmetic encoding of the first flag and the second flag is switched (S712).

    Abstract: A coding method of coding a first picture group and a second picture group that are interlaced and captured at different view points, said coding method comprising: 5 defining an access unit including a picture of the first picture group and a picture of the second picture group that corresponds to the picture of the first picture group; and coding each of the pictures included in the access unit, the access unit being defined in said 10 defining, wherein said defining includes: determining a unit of coding for determining whether the pictures included in the access unit are to be uniformly coded on a per-field basis or on a per-frame basis; and determining a field type for determining whether the pictures are to be 15 uniformly coded as top fields or bottom fields, when it is determined in said determining of a unit of coding that the pictures included in the access unit are to be coded on a per-field basis, said coding includes: coding the picture of the first picture group, using a predictive 20 picture generated from a picture of the first picture group; and coding the picture of the second picture group, using one of (i) a predictive picture generated from a picture of the second picture group and (ii) the predictive picture generated from the picture of the first 25 picture group, within the access unit including the picture of the second picture group, and in said coding, each of the pictures is coded for each access unit in a format determined in said determining of a unit of coding and in said determining of a field type. 2949123_1 (GHMatters) P84360.AU.1 11/11/11 Code view components in access unit Determine reference field-pic flag value S502 Field-pic-flag equal to ""?
