Tuning the Gamma Feature

This section describes how to tune the Gamma feature to control the 12-bit R, G, and B gamma lookup tables used by the gamma correction module after alpha blending within a DC8200.

Before you begin

Make sure:
  • The details view shows the settings of the Gamma feature for a DC8200 project.

    For information about how to show the settings in the details view, see Tuning a DC8200 Feature.

  • The VTunerClient is connected to a VTunerServer that works with a DC8200.

    For information about how to set up a connection to a VTunerServer, see Setting Up a Connection to a VTunerServer.

Procedure

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

Results

  • The tuning results are printed in the Console view in real time.
  • The image displayed on the VTunerServer side is updated.
