矯飾。
偽色（細節）。
| Signal processing (especially operations performed during RAW conversion) can cause significant visual artifacts, including oversharpening “halos” and loss of fine, low-contrast detail. These artifacts result from nonlinear signal processing (so-called because it varies with the signal). Log frequency-Contrast chartImages may be sharpened (MTF boosted) in the presence of contrasty features like edges and blurred (lowpass filtered) in their absence. This generally improves measured performance (both sharpness and noise/Signal-to-Noise Ratio (SNR)), but it may result in a degradation of perceived image quality, for example, a “plasticy” cartoon-like appearance of skin even though edges are strongly sharpened. This loss of detail cannot be measured with SFR. |
| 信號處理(特別是在原始轉換過程中執行的操作)可能導致顯着的視覺偽影，包括過度銳化“光暈”和丟失精細、低對比度的細節。這些偽影是非線性信號處理的結果(因為它隨信號的變化而變化)。日志頻率-對比度圖表圖像可能被銳化(MTF增強)，在出現對比特征，如邊緣和模糊(低通濾波)，在他們沒有。這通常提高測量性能(銳度和噪聲/信噪比)，但它可能導致圖像質量下降，例如，一個“塑料”卡通樣的外觀，即使邊緣是強烈銳化。這種細節的損失不能用SFR來衡量。 |

An 8-bit color cube does not have enough data in its root sector to support an unmodified logarithmic remap without producing undesirable artifacts
原文對antifact的注解：
Artifacts include striping, chroma noise, and sparse-data noise
偽影包括條紋、色度噪聲和稀疏數據噪聲。
方塊效應，銳化造成的亮邊，毛刺等。
