    摘要: Recent video coding schemes support different size of interpolation filter length for interpolation process. However, the schemes are using fixed, one sized interpolation filter length for all different size of picture resolutions and all different size of inter predicted units, leading to undesired large memory bandwidth usage. Especially for large spatial resolution images or large prediction blocks, the required memory bandwidth is substantially increased by using fixed interpolation filter length. The current invention provides methods and apparatuses for selecting the different interpolation filter coefficients adaptively based on a pre-determined interpolation filter length selection scheme. The benefit of the current invention is in the form of saving memory bandwidth usage.

    摘要: An image coding method determines one of frame coding and field coding while suppressing an increase in the complexity. The image coding method includes coding a current picture included in the pictures; determining whether a picture next to the current picture is to be coded in frame coding or field coding, depending on motion information that is information for indicating a motion in the current picture; and coding the next picture in frame coding when it is determined in the determining that the next picture is to be coded in frame coding, and coding the next picture in field coding when it is determined in the determining that the next picture is to be coded in field coding.

    摘要: An image coding method decodes a coded stream which is generated by inter prediction coding a moving picture and includes processing units and a header of such units, the processing units including at least one processing unit divided in a hierarchy, the hierarchy including: a highest hierarchical layer in which a coding unit is a largest processing unit; and a lower hierarchical layer in which a prediction unit exists. The method comprises: identifying, by parsing hierarchy depth information stored in the header and indicating a hierarchical layer higher than a lowest hierarchical layer in which a smallest prediction unit exits, a hierarchical layer which is indicated by the hierarchy depth information or a hierarchical layer higher than the indicated hierarchical layer, the hierarchical layer having a prediction unit that stores an adaptive motion vector resolution switch flag necessary for decoding; and decoding the prediction unit, using the flag.
