Black Level#
例如，您可以將影像中每個像素的灰階值增加 3。
使用此功能#
資訊
Basler 建議在使用任何色彩增強功能（例如 Balance White、Color Transformation 或 Gamma）之前，先將黑階設定為 0。套用色彩增強功能後，您可以根據需要變更黑階。不過，增加黑階會降低色彩準確度。
設定 Black Level#
- 如果可用，請將
BlackLevelSelector參數設為所需的值，例如：All. -
為
BlackLevel參數的值。- 由
BlackLevel參數值 產生的灰階值變化取決於相機型號. - 將黑階值指定為 0 等同於停用相應的調整。
- 由
Black Level Selector#
在 racer 2 L 相機型號， BlackLevelSelector 參數可用。如果相機在 Dual 或 Quad Line 模式下運作，此參數可讓您將黑階全面套用或套用到特定行 感測器擷取模式.
您可以將 BlackLevelSelector 參數設為下列其中一個值：
All：全面套用黑階。Line1,Line2,Line3,Line4：將黑階套用到第 1、2、3 或 4 行。
資訊
- 只有在啟用 Dual Line sensor acquisition mode 時，為第 2 行指定的黑階值才會生效。同樣地，只有在啟用 Quad Line sensor acquisition mode 時，為第 3 行和第 4 行指定的黑階值才會生效。
- 為指定之
All的黑階值會加上為指定之Line1,Line2,Line3的狀態，以及Line4指定的增益值的總和。 - 如果您正在使用 Shading Correction 功能的 DSNU 校正，則在調整感光元件黑階之後，必須再次 create 用於 DSNU 校正的陰影校正集。
Black Level Compensation#
Dark current 可能會對影像 Quality 產生負面影響。某些影像感光元件可以透過自動調整黑階來補償此情況。
在 某些相機型號，您可以使用手動方式啟用或停用此自動調整 BslBlackLevelCompensationMode 參數的值。
若要這樣做，請將 BslBlackLevelCompensationMode 參數設為下列其中一個值：
Sensor：由影像感光元件執行黑階補償。感光元件會嘗試補償會影響信號的熱生成電壓（dark current）。Off：停用黑階補償。這在進行微弱光信號的定量分析時，或者當您需要不含 dark current 校正的原始影像資料時非常有用。
將補償模式設定為Off會重設用於黑階補償的所有內部校正值。
