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.

Abstract: A decoding apparatus has an arithmetic decoder and a controller. A counter logic of the controller generates a first statistics result according to a first syntax element decoding result. A control logic of the controller instructs the arithmetic decoder to perform a first scan procedure at least once to generate the first syntax element decoding result of transform coefficients of a transform coefficient block, controls a repetition number of a second scan procedure based at least partly on the first statistics result, and instructs the arithmetic decoder to perform the second scan procedure at least once to generate a second syntax element decoding result of the transform coefficients. The first scan procedure decodes a first coded syntax element of one transform coefficient when performed by the arithmetic decoder once. The second scan procedure decodes a second coded syntax element of one transform coefficient when performed by the arithmetic decoder once.
