TWAIN :: Avision.com

	Avision's easy-to-use TWAIN driver provides various useful features such as auto color detection, color matching, multi-feed detection, and blank page removal to enhance your image quality and improve your productivity.

Scan one image and show 2~3 images in different image modes in one time. Scan one image and show 2~3 images in different image modes in one time. Scan one image and show 2~3 images in different image modes in one time.
Automatically scan color image for color document, black and white image for black and white document. With Auto Color Detection, the scanner eliminates the pre-sorting of batched documents and the inserting of separator sheets previously needed to divide color and blank and white document. With this feature, your storage space is significantly reduced.
When the original documents are contaminated or damaged, containing marks, white fonts, etc., the intelligent image enhancement tool helps you create sharp and crisp image.
If your A4 duplex scanner came with a front input tray, the scanner allows you to scan an A3 size document in an innovative way. Simply fold your A3 document into A4, and then load the paper in the front tray. Choose Merge Two Sides from the TWAIN user interface, the scanner is able to scan both sides of your folded A3 document and then merge two A4 image into one A3 image.
Use the default parameters to get the accurate colors of your pictures.
The TWAIN driver allows you to drop either of the red, blue, or green color channel in your scanned image. If your image contains red color watermark or background, choose the R (Red) channel then the red watermark or background will be removed. This feature is used to sharpen your text when using OCR ( Optical Character Recognition ) software. This function applies to gray or black and white image modes.
Crop different areas on your documents and deliver these images in B&W, Gray, or Color separately. For example, you may need to scan the photo area of your resume in color and the entire document in black and white to save your storage space.
Blank pages can be automatically detected and removed. This feature reduces file size by deleting blank pages within a scanned image. In addition, it also reduces document preparation as you can put both simplex and duplex documents in the same batch.
Documents can be scanned in any orientation, reducing the preparation requirements. This feature electronically rotates the image so that it can be displayed in a proper orientation by the scanner operator.
Invert: Reverse the brightness and the colors of your image. Mirror: Reverse the left and right side of your image.
Automatically crop documents according to their paper size.
Place multiple documents on the flatbed and create multiple individually cropped images in one scan.

Occasionally small dots or specks appear in the background of a scanned image. Remove unwanted speckles provides a cleaner image for OCR ( Optical Character Recognition ) processing, and also helps to reduce compressed file size.
The tool is used for keeping track of documents by using inkjet cartidge to print a varity of text massages on each scened document.
The tool is used for keeping track of documents to stamp text on your scanned images.
The reliable paper feed system lets you scan unusually long document. This is ideal for scanning engineering diagram or other special documents.
Multi-Feed Detection by length Detect overlapped document that go through the auto document feeder by defining the length of document being multi-fed. Ultrasonic Multi-Feed Detection (optional) Ultrasonic multi-feed uses sound waves to detect multiple documents going through the scanner at the same time. This technology consists of two sensors: a transmitter below the paper transport and a receiving sensor above. When the paper passes through the scanner, an ultrasonic sound wave is passed through the paper. Since there is only one solid medium ( paper ), the sound is easily detected. If multiple documents feed through, the thickness between the pages weakens the signal. And the receiver interprets this as a multi-feed. Intelligent Mode (Skip Multi-Feed) by Ultrasonic Detection Some document which are glued with a photo or a label may easily be detected as multi-feed yet you wish to bypass these multi-feed conditions.
