Description
The detection functions of the DR-S250N scanner are described below.
Solution
- Auto Resolution Detection
When enabled in the CaptureOnTouch or scanner driver settings, this function detects the content of documents and determines the scanning resolution automatically. It can optimize the file size.
- Auto Color Detection
Automatically detects whether scanned documents are color, grayscale, or black and white.
- Paper Size Detection
Detects the size of the scanned document and creates an image without margins.
- Content Skew Correction
Even if the print on the document is skewed, it is corrected to be straight.
- Character Emphasis
You can adjust the thickness of characters and lines, improving the OCR processing accuracy for characters with thin lines.
- Ultrasonic Double Feed Detection
The scanner stops feeding when the ultrasonic sensor detects that two or more document pages are feeding at the same time.
- Text Orientation Detection
The text orientation on each page is detected, and the scanned image is rotated in 90-degree increments as necessary for normalization.
- Text Enhancement Modes
The scanner is equipped with three functions to improve the visibility and OCR processing accuracy of documents with low character visibility.
- Advanced Text Enhancement mode
: Makes documents with a dark background or uneven background easier to read.
- Advanced Text Enhancement II mode: Makes it easier to read characters on documents with a uniform background and faint characters and background.
- Active Threshold mode: Can batch process various types of documents, such as documents with faint characters or stains, at once.
- These modes may not work, depending on the type of document.
