Mode |
Mode represents the method to be used for tone balancing.
-
•From Reference - Utilizes a source image color table to balance the selected images. From Reference should be used when one image of the mosaic, or an area of the image, looks particularly good and all other images of the mosaic should look similar. Tone Balance is performed for each selected image, except the reference image, to match the Reference Area. The Reference Area is selected by using one of the available options under the Source Area option list
Note: When Average is selected, only Entire Images and Overlaps are available from the Source Area option list. The other areas, Block, Oriented Block, Element and Fence are not available.

Source Area |
Source Area represents the area of the selected images to which tone balance will be applied. Possible areas are listed below.
-
•Entire Images
Average mode:
All pixels of all selected images are used for the Balance Tone computation.
From Reference mode:
The complete reference image will be used. The Histogram of the Reference image is applied to the selected images.
-
•Overlaps
Average mode:
Only the overlapping pixels of all the selected images are used for the Balance Tone computation.
From Reference mode:
Pixels of the overlapping portion of the reference are used to compute the new histogram that is applied to all selected images.
-
•Block (Available with From Reference only)
In the Block source area, the area is chosen by entering a block shape selection on the Reference Image. This technique allows you to sample pixels of a specific area of the reference image.
-
•Oriented Block (Available with From Reference only)
In the Oriented Block source area, the area is chosen by entering an oriented block shape on the Reference Image. This technique allows you to sample pixels of a specific area of the reference image.
-
•Element (Available with From Reference only)
In the Element source area, the area is chosen by selecting a closed design file element. This technique allows you to only sample pixels of a specific area of the reference image using a non-reticular shape. The pixels comprised inside the element are used to compute the new histogram that will be applied to all the selected images.
-
•Fence (Available with From Reference only)
In the Fence source area, the active fence is used to select the pixels that are used to compute the new histogram that is applied to the selected images.
