4 If necessary, use the VRS Adjustment Controls to adjust the image property

settings to suit your preferences. For more information, refer to Using the VRS

Adjustment Controls on page 48.

them as a profile. Refer to Working with Profiles on page 31.

6 When you are satisfied with the preview image, select OK from the VRS

Adjustment Controls. The property settings are saved and put into effect for

the next batch of documents that you scan with VRS. Note that the preview

image is discarded; it is not sent to the scanning application.

Using the Status and Analysis Information

The VRS Interactive Viewer gives you image status information, along with analysis

statistics that summarize the properties for the current image in the viewing pane.

The image status message appears in the title bar and indicates the status of the

current image, such as “Status: OK” or “Brightness Out of Range.”

Figure 2-23. Image Status Information

The image analysis information appears in the VRS Interactive Viewer status bar and

includes the following properties:

 Size: Lists the image dimensions in pixels.

 Skew: Lists the detected skew angle in degrees.

 Brightness: Lists the detected brightness value as a percentage.

 Contrast: Lists the detected contrast value as a percentage.

 Color: Lists the detected image type as “color” or “bitonal,” along with a

confidence value expressed as a percentage. The percentage is listed only if

Automatic Color Detection is enabled.

 Speckles: Lists the number of pixels that are removed from the image when

Speckle Removal is selected from the Noise panel.

The analysis information can help you identify appropriate threshold values for

contrast, brightness, and color confidence on the Warnings tab in the VirtualReScan

Administration Utility, as well as for settings for the VRS Adjustment Controls.You

cannot edit the analysis information on the status bar (Figure 2-24).
