(三维)。其差异在于，两者查询数据以修正色彩值的方式。1D LUT 依赖红色、绿色及蓝色的单一颜色来区别单向线的色彩。这对于一般使用的显示器已经足够，但对于需要精准复制色彩，或是需要使用进阶影片编辑软件的色彩专业人士来说，3D LUT 会更符合需求。请想象各色彩都为三个变量 (RGB)，而输出有对应各色彩的值，例如，假设输入值为 100，则输出显示值要为 R = 88、G = 26 且 B = 10，才能重现输入色彩值。</p><p>这些 LUT 在传统上也提供 8 位或 10 位版本，并且分别使用 1,677 万色至 10.7 亿色来重现色彩。其色彩潜力非常高，但相较于 3D LUT 来说，1D LUT 全都受到线性程序的限制，而且更容易发生错误，色调范围也较小。此外，由于只有 256 阶可以应用，因此每个 RGB 色彩输入讯号都有 8 位也不会产生令人印象深刻的多层次。另一个 10 位输出正逐渐成为标准，但由于原先使用 8 位输出的 Windows 近期刚升级，这对于色彩专业人士来说可能仍嫌不足。透过此次的升级，不论色彩处理器采用 1D 或 3D LUT，使用者都可利用更高位的 LUT 来使其发挥更多效能。</p><p><img alt="" class="img-responsive"

兆色調色盤</h3><p>拥有更高位计数 (14 位) 的优点在于，色调转换更精准且可用的调色盘增加。这项能力让更高位的 LUT 能提供很高的满意度，因为色彩数的增加可创造出更加平滑的色彩转换，特别是较暗色渐层的转换。高位 LUT 非常适合进行完美颜色管理，完全符合要求高质量色彩之程序的需求。更高的位计数也能创造更精准的 Gamma 转换，提高灰阶呈现的平滑度。此 RGB 透明混合有助使用者精确符合自身需求，同时降低色彩错误，并精确重现色彩输入。通过运用更大型调色盘的先进 ViewSonic 12 位色彩引擎，彩色显示器将提高输出，即使计算机输入讯号的比特率较低，由于色彩引擎的比特率较高，且采用先进的 LUT，因此您仍将获得更佳的色彩重现。此外，使用增强的 12 位色彩引擎及纯量，可提高色彩精确度并降低 Delta E 数值，带来更大的调色盘与令人惊讶的精确重现。</p><p><img alt="" class="img-responsive" src="https://www.viewsonic.com/vsAssetFile/jp/img/colorpro/upload/14-bit-LUT-02-02.jpg" style="margin:auto;"/></p></div></div><div class="row"><div class="col-md-12"><div class="col-md-6"><h3>3D LUT</h3><p>当试图为每种颜色找到正确的阴影值时，以线性方式显示色彩可能造成配对错误。3D LUT 的效果更佳，因为它们使用体积色彩空间产生色彩，这能更加准确显示色彩并减少校准误差。3D LUT 有助于建立更好的色彩渐层，并用于表示存在于现实生活中的非线性值。当能够更佳配对色彩浓淡以建立更佳色彩重现时，尤其是在编辑过程或使用者处理色度、色调和亮度时，则可呈现更宽的色域范围和色彩饱和度。将一个色彩空间转换成另一个色彩环境的成效更佳。当将一个色彩空间转换为另一个色彩空间时，3D LUT 更为精确，可减少原始色域中遗失的色彩信息。3D LUT 的非线性行为改善了中间色彩渐层，从而提高了灰阶准确度。</p></div><div class="col-md-6"><img alt="" class="img-responsive" src="https://www.viewsonic.com/vsAssetFile/jp/img/colorpro/upload/3d-lut.jpg"/></div></div></div><h3
