Procedure

  1. In the upper-left corner, select the Enable Degamma Correction check box to enable the de-gamma correction module.
  2. Under Curve Type, select PQ Curve or User Curve for de-gamma curve configuration.
  3. If User Curve under Curve Type is selected, specify the de-gamma value in the Degamma Value spin box under User Curve.
  4. In the Control Points spin box, specify the number of control points in the de-gamma curve.
  5. To further adjust the de-gamma curve, drag each point in the plot to tune the de-gamma mapping value.
    Alternatively, double-click each cell in the control point table and modify the value of the point.
