摘要： In the case where an input image is an image of a non-YUV420 format and an encoding unit is the smallest CU block, an adaptive-sub-sampling luma reference pixel acquisition unit sub-samples reference pixels existing neighboring a luma block corresponding to a chroma prediction target block based on a luma intra prediction mode, and acquires a pixel value of each of the sub-sampled reference pixels. In the case where the input image is an image of a non-YUV420 format and the encoding unit is the smallest CU block, an adaptive-sub-sampling chroma reference pixel acquisition unit sub-samples reference pixels existing neighboring the chroma prediction target block based on the luma intra prediction mode, and acquires a pixel value of each of the sub-sampled reference pixels.

摘要： An intra prediction unit that performs intra-frame prediction includes a luminance reference pixel acquisition unit and a chrominance reference pixel acquisition unit. When the coding unit is set to a smallest CU block, the luminance reference pixel acquisition unit subsamples reference pixels arranged at integer pixel locates neighboring a luminance block that corresponds to a chrominance prediction target block, and acquires the pixel values of the reference pixels after the subsampling. Furthermore, when the coding unit is set to a smallest CU block, the chrominance reference pixel acquisition unit subsamples reference pixels arranged at integer pixel locates neighboring the chrominance prediction target block, and acquires the pixel values of the reference pixels after the subsampling. Such an arrangement is capable of reducing the number of reference pixels used to reduce the redundancy between the color components.

摘要： A communication control apparatus, in a wireless communication system having an area in which coverage areas of a macro cell base station and a small cell base station using different frequency bands overlap, includes a storage unit and a control unit. The storage unit stores small cell base station information indicating whether the small cell base station is present within a coverage area of a macro cell base station. The control unit instructs a radio terminal apparatus present within the coverage area of the macro cell base station to perform quality measurement in a frequency band of the small cell base station when the small cell base station is present within the coverage area of the macro cell base station based on the small cell base station information.
