• 4096*4096: Divide the color balancing area into 4096x4096 sub-regions.
• 8192*8192: Divide the color balancing area into 8192x8192 sub-regions.

Adjust the brightness of the result image. The value range is [-100, 100], with a default of 0.0.

The larger the value, the higher the brightness of the result image.

Adjust the contrast of the result image. The value range is [-100, 100], with a default of 0.0.

The larger the value, the stronger the contrast of the result image.

Adjust the saturation of the result image. The value range is [-100, 100], with a default of 0.0.

The larger the value, the stronger the saturation of the result image.

This parameter is available only when Mask Data is checked.  Not provided when executing a production workflow.

Specify the data source where the mask dataset resides.

This parameter is available only when Mask Data is checked. When executing a production workflow, it uses the mask data from True Color Output by default.

Specify the vector surface dataset used as the mask. The dataset must contain an ImageName field, and the name must correspond to the name of the image currently being processed.

Set the resolution used for the color balancing preview.

Lower resolution (larger downsampling factor) preview is smoother but blurrier; higher resolution (smaller downsampling factor) preview refreshes slower but is clearer. This setting only affects the preview and does not affect the quality of the final output result.

The available options are as follows:

• Downsample 4 times (default): Preview resolution is 1/4 of the original image.
• Downsample 8 times: Preview resolution is 1/8 of the original image.
• Downsample 16 times: Preview resolution is 1/16 of the original image.
• Downsample 32 times: Preview resolution is 1/32 of the original image.
• Downsample 64 times: Preview resolution is 1/64 of the original image.
• Downsample 128 times: Preview resolution is 1/128 of the original image.
• Downsample 256 times: Preview resolution is 1/256 of the original image.
• Downsample 512 times: Preview resolution is 1/512 of the original image.

Set the storage path for the result image after color balancing.

If executing a production workflow, use the Processing path parameter in Set Image Path or Add orthophoto, and it cannot be edited.

Specify the resampling method used during the image processing.

Three options are provided: Nearest, Bilinear, Cubic, with a default of Bilinear. For more method descriptions, refer to Resampling Method.

Specify the method for setting the output image resolution. Provides the following options:

• Original resolution (default): Retain the original resolution of the input image.
• Fixed Value: Use a fixed input value as the output image resolution.
• Custom: Specify the output resolution according to different satellite sensor types. After selecting this option, a dialog box will appear for detailed settings. In the dialog box, you can click the Add button in the toolbar to add a row; then click the cell in the Satellite Sensor Type column to select the sensor type; finally, enter the corresponding resolution in the Resolution column cell.
  Notes:

  • If the corresponding satellite sensor type is not found, select the USEDEFINE option. The system will use the resolution set for this option to output data for all satellite sensor types not listed.
  • If multiple satellite sensor type image data (e.g., ZY3, GF-2, LandSat) are processed together, but only the resolution of one satellite sensor type (e.g., only ZY3) is set, other satellite sensor type images (e.g., GF-2 and LandSat) will be output at their original resolution.

Set the storage format of the result image. Provides the following options:

• Not set: Output using the original image format.
• Tiff/GeoTIFF (default): Output the result image in Tiff/GeoTIFF format.
• Erdas Image: Output the result image in Erdas Image format.
• PCIDSK: Output the result image in PCIDSK format.

If executing a production workflow, use the Output format parameter in Set Image Path or Add orthophoto, and it cannot be edited.

When Output Format is Tiff/GeoTIFF, set the compression method for the output image.

Four options are provided: NONE, DEFLATE, LZW, JPEG, with a default of NONE. For more method descriptions, refer to Compression method.

If executing a production workflow, use the Compression method parameter in Set Image Path or Add orthophoto, and it cannot be edited.

If checked, the result data will use the same image coordinate system as the input data. If not checked, use the Output coordinate system parameter in Set Image Path or Add orthophoto, and it cannot be edited.

This parameter is available only when the function is launched from the Imagery tab -> DOM Data Production group -> Image Color Balancing.

Checked by default. After successful execution, the result data is automatically added to the current map window for display.

Checked by default. Image pyramids will be built for the output image data, thereby improving the zoom browsing speed and display performance of large volume images.

If executing a production workflow, use the Create Image Pyramid parameter in Set Image Path or Add orthophoto, and this parameter will not be displayed.

This parameter is available only when Create Image Pyramid is checked.

Specify the resampling method used when creating image pyramids. Provides NONE, Average, Nearest Neighbor, Gaussian Kernel, with a default of Average. For more method descriptions, refer to Resampling Method.

If executing a production workflow, use the Resampling Method parameter in Set Image Path or Add orthophoto, and this parameter will not be displayed.

Image statistics are used to optimize the stretch effect during display. If the image has no statistics, the image will be displayed using the default stretch method, and 8-bit data will not be stretched.

• Checked (default): Create statistics for the image in the background without affecting the workflow execution.
• Unchecked: Create statistics during the execution of this tool, which may consume time.

If executing a production workflow, use the Asynchronously create statistics parameter in Set Image Path or Add orthophoto, and this parameter will not be displayed.
