詳細介紹
For high dynamic range cameras, the OECF charts with patches calculated according to ISO 14524 are not that convincing. Densities are calculated according to the cube root formula result in large steps in the high-density patches. Image Engineering’s solution for the problem is the TE269, a 36 patch OECF chart which basically follows ISO 14524 but implements additional steps especially at higher density levels.
使用OECF圖表根據ISO14524計算高動態相機范圍是不可靠的。密度是根據高度板塊多次立方根公式的計算結果得來的。對于這個問題的解決方法是采用TE269,這一個36個小區域遵循ISO 14524標準排列的 OECF圖表,但實現了額外的步驟,特別是在高密度水平測量。
