摘要： The present invention makes it possible to include, when encoding processing is applied to three color components using a 4:0:0 format, data for one picture in one access unit and makes it possible to set the same time information or the same set encoding modes among the respective color components. In an image encoding system for applying compression processing to an input image signal including a plurality of color components, encoded data obtained by independently subjecting an input image signal of each of the color components to encoding processing and a parameter indicating which color component the encoded data corresponds to are multiplexed with a bit stream. In an image decoding system for inputting a bit stream in which an image signal including a plurality of color components is compressed to perform decoding processing, decoding processing of the encoded data of each of the color components is performed using a parameter indicating which color component the encoded data corresponds to.

摘要： An image decoding device method for obtaining image signals by decoding compressed data of digital moving image signals in a 4:4:4 format is disclosed. An identification signal is decoded, the identification signal indicating whether three color component signals have been encoded in a common encoding mode or in independent encoding modes. The common encoding mode corresponds to a process of encoding the three color component signals of one frame by a common macroblock type information and the independent encoding mode corresponds to a process of encoding the three color component signals of one frame by an individual independent macroblock type information. The three color component signals are decoded in a common encoding mode or in independent encoding modes according to the identification signal.

摘要： A moving picture decoding method and a decoder for restoring a moving picture signal is disclosed. The decoder includes a decoding unit that decodes the differential signal, a motion vector, and a shape information indicating a shape of a block that becomes a unit for the motion compensated prediction by using an encoded bitstream. The shape information indicates an accuracy of virtual pixel and an interpolation filtering method. The decoder also includes a motion compensating unit that determines that the accuracy of virtual pixel and the interpolation filtering method is to be used in generating the predicted picture based on the shape of the block that becomes the unit for the motion compensated prediction, and generating the predicted picture containing the virtual pixel with reference to the reference pictures stored in a frame memory using the motion vector decoded by the decoding unit according to a determination result.
