Tuning the 3DLUT Feature in Direct Mode

This section describes how to tune the 3DLUT feature in direct mode.

Before you begin

Make sure:
  • The details view shows the settings of the 3DLUT feature for a DC8200 project in direct mode.

    To tune this feature, you need to choose Display > 3DLUT > Direct Mode in the Features view. For more details, see Tuning a DC8200 Feature.

    Figure 1. Details View in Dragging Mode When Direct Mode under 3DLUT Is Selected

  • 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 check box to enable the 3D LUT module.
  2. From the Enlarge drop-down list, select one of the following options to specify the enlarge mode for color channel values:
    • vivLUT_ENLARGE0: does not enlarge color channel values.
    • vivLUT_ENLATGE9: enlarges each color channel value by 2n, where:

      n = 9 - Bit width of the greatest value among the red, green, and blue channels

    • vivLUT_ENLATGE10: enlarges each color channel value by 2n, where:

      n = 10 - Bit width of the greatest value among the red, green, and blue channels

  3. Select Single Point Precision Mode or Dragging Mode.
  4. If Dragging Mode is selected, drag mesh grid nodes to tune color mappings.
    You can use the color searcher on the right to easily locate a color zone. To use the color searcher, enter a set of RGB indexes in the text box and click Search. Each index must be in the range from 0 to 16, inclusive, and separated with a comma (,).
    Note: HSV-based tuning is not supported. Intersection between grid nodes is not supported.
  5. If Single Point Precision Mode is selected, perform the following steps.
    Figure 2. Details View in Single Point Precision Mode When Direct Mode under 3DLUT Is Selected

    1. In the Index text box, enter a set of RGB indexes to choose a point from the table.

      Each index must be in the range from 0 to 16, inclusive, and separated with a comma (,).

      You can use the index filter in the bottom-left corner to query the RGB indexes of a color. To use the index filter, enter a RGB color based condition and click Search to list the indexes of all RGB colors that meet the condition.

    2. Click the Color Picker button and select a color as the mapped color.

      Then, the color mapping is added to the color table on the right.

    3. Repeat Step 5.a and Step 5.b to add all color mappings.
    4. (Optional) To delete a color mapping from the color table, right-click the corresponding row and choose Delete from the context menu.
    5. (Optional) To modify a mapped color, double-click the cell in the New(R,G,B) column and enter the new RGB color.

Results

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