Lines Matching refs:luma

1076 monochromatic light intensity (often called "`luma`") and color differences
1079 components at lower spatial resolution than the luma component.
1093     compared with luma: there are unique chroma samples for each texel.
1096     resolution of luma in that dimension.
1100     resolution of luma in both dimensions.
1103 accessing both chroma and luma values at the same location.
1105 components at the location of the luma samples must be reconstructed from
1109 The location of the chroma samples relative to the luma coordinates is
1115 coordinates and (_i_,_j_) integer texel positions in the luma component
1123 If the chroma values are reconstructed at the locations of the luma samples
1306 This will not have any visible effect if the locations of the luma samples
1312 if the component has a downsample factor of two relative to the luma
1370 contains luma.
