    摘要: There are provided an encoding device, a decoding device, an encoding method, and a decoding method that enhance optimality in a case of encoding moving image signals having no sample ratio distinction between color components such as a 4:4:4 format. In a case of conducting compression encoding by inputting digital moving image signals of the 4:4:4 format, there are prepared a first encoding process of encoding three color component signals of the input moving image signals in a common encoding mode, and a second encoding process of encoding the three color component signals of the input moving image signals in respective independent encoding modes. The encoding process is executed by selecting any one of the first encoding process and the second encoding process, and the compression data contains an identification signal for specifying which process is selected.

    摘要: Encoding and decoding are uniformly carried out for a plurality of chroma formats. Based on a control signal for providing a chroma format type of an input moving image signal, in the case of a chroma format of 4:2:0 or 4:2:2, a first intra prediction mode deciding unit and a first intra prediction image generation unit are applied to a luminance component of the input moving image signal, and a second intra prediction mode deciding unit and a second intra prediction image generation unit are applied to a chrominance component. In the case of a chroma format of 4:4:4, the first intra prediction mode deciding unit and the first intra prediction image generation unit are applied to all color components to carry out encoding, and a variable length encoding unit multiplexes the control signal as encoding data to be applied to a moving image sequence unit on a bit stream.

    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.
