TopOCR's Real-Time Document Camera Image Preview Dialog
The DocCam Image Preview Dialog lets you use your document camera as a high quality scanner.
You can launch this dialog by simply clicking on the Image Window's (left window) top level DocCam menu item.
When you launch this dialog, you can use the "Esc" key as a "hotkey" to scan an image, or you can use the Dialog's Scan Image button to scan an image.
You can even add a USB foot switch set to emulate the Esc key without time delay to gain maximum scanning speed.
The capture delay makes it easier for you to use your hands to hold documents (particularly books) flat to reduce page curl.
This approach of using hand-flattened documents with a document camera can allow you to acquire and process images much faster than a flat-bed scanner!
