摘要： The present technology relates to an encoding device and an encoding method capable of reducing the amount of information relating to information that specifies a reference image.
An encoding unit generates a predicted image using a reference image. A transmission unit transmits inter_ref_pic_set_prediction_flag representing whether reference image specifying information specifying the reference image of a prior image that is an image prior to a current coding image in coding order is used as the reference image specifying information of the current coding image in a case where the current coding image is an image other than a first image of a GOP (Group of Picture). The present technology, for example, can be applied to an encoding device of an HEVC (High Efficiency Video Coding) system.

摘要： An image processing system, method, and program suppress block distortion when decoding block-encoded image data. Filtering content to be applied to the block image data is selected based on the encoding types of the block image data to be filtered. A filter filters block image data according to the selected filtering content.

摘要： The present invention relates to an image processing device and method, which realize improvement in encoding efficiency for color difference signals and reduction in address calculations for memory access. In a case where a block size of orthogonal transform is 4×4, and a macroblock of luminance signals is configured of four 4×4 pixel blocks appended with 0 through 1, the four luminance signal blocks are corresponded with one color difference signal 4×4 block appended with C. At this time, there exist four motion vector information of mv0, mv1, mv2, and mv3, as to the four luminance signal blocks. The motion vector information mvc of the one color difference signal 4×4 block is calculated by averaging processing using these four motion vector information. The present invention can be applied to an image encoding device which performed encoding based on the H.264/AVC format, for example.

摘要： An apparatus includes at least one processor provided with at least one memory that includes computer program code. The memory and the computer program code are configured, when working with the at least one processor, to cause the apparatus to decode, from a bitstream, quantized transform coefficient data for 16×16 transform unit, and an 8×8 quantization matrix and to inversely quantize the quantized transform coefficient data for 16×16 transform unit using a 16×16 quantization matrix. The 16×16 quantization matrix is set by duplicating at least one of two elements adjacent to each other in the decoded 8×8 quantization matrix.
