Restarting the Image Capture after Stopping
If you stopped capturing images to a folder before it was closed, you can continue to capture images to that folder.
Step 1: To continue working on this folder, in the Green section of the home screen, click Continue Imaging Folder to display the drop-down list of the most recent folders worked on.
Step 2: Click the correct folder. A calibration check dialog box displays.
Step 3: On the calibration check dialog, click Yes or No.
Step 4: Continue to capture images.
Switching Tasks While Capturing Images
You can interrupt the image-capture process to do other things while you are working on a folder that is not completed, allowing you to switch tasks.
Step 1: To return to the DCam home screen, on the tool bar, click Home.
Step 2: From the home screen, switch to a different task.
Refocusing During Capture
Periodically throughout the day, refocus the camera when capturing images, especially when capturing a thick book. To select focus, at the top of the screen on the image viewer toolbar, click Focus or Ctrl+F.
Note: Refocusing may affect the other calibration settings, requiring you to complete all other calibration steps. For details on calibrating, see Color Calibration and Grayscale Calibration.
For a thick book, as pages are turned, the distance between the camera and the surface of the page changes. The camera is in focus only for about 0.5 inch (1.27 centimeters) of the pages. When that thickness of pages has been captured, you need to refocus the camera. If required for accuracy, as capturing progresses, use a measuring tape to check the distance.
Adding a Folder Comment During Capture
You can add folder comments to report missing pages or overall quality issues. These comments are included with the record capture status comments for the folder as a whole, not for a specific image. You can add comments as you capture. Since they accumulate in the folder, you can see all comments that you added previously.
Note: When you create a new folder, comments from that listing or from a previous folder might display. Review those comments. If they do not apply to the current folder, delete them.
Examples of appropriate comments, include the following:
- “Pages 77–92 are missing.”
- “Due to restrictions, some information is covered up.”
- “Book sheets are brittle. Not able to digitize because of their fragile state.”
- To add a comment, click the Comment X-Key button, enter your comments, and click Save.
Image Quality Checks During Image Capture
DCam shows the Quality Checks window at 2 different times: during image capture and during image evaluation. The goal of image quality checks during the image capture process is to catch photographic problems immediately, rather than waiting for the evaluation process—at which point you will evaluate all of your captured images at the same time with a more methodical approach. (See Image Quality Checks and Feedback Errors.)
If enabled in the quality check tab in preferences, the quality checks warning dialog box displays when DCam detects an image quality issue with either clipping or out of focus parameters. It displays the image ID number and status of each type of quality check for that image. At the same time, Dcam also flags the images.
Note: You can configure the quality checks. In the dialog box, click Configure Quality Warnings, or open the Quality Check tab in preferences. (See Quality Check.)
To review and clear warnings at any time, in the image viewer toolbar, click the Quality Checks icon. The quality checks dialog stays open until you close it. (To work with flagged images, see the Addressing Flagged Images section.)
Note: Only clear a warning if an image retake has failed after diligent effort to correct conditions. Cleared warnings may trigger additional attention during the manual headquarters audit. Hover the mouse cursor over the blue information icons to see additional information, including guidance for correcting the issue.
Addressing Flagged Images
A flagged image is one that has been marked in some way to indicate that the folder cannot be closed and transferred to headquarters. There are 3 types of flagged images:
- Quality check warnings
- Capture errors
- Manually flagged
You can go to the evaluate panel and review flags during image capture. See Flagging Images for Later Review.
