Dynamic Web TWAIN vs. ImageCapture Suite

Last Updated on 2018-10-10


Both Dynamic Web TWAIN and ImageCapture Suite are web-based image capture SDKs from Dynamsoft. Dynamic Web TWAIN was first released in 2003. Since then it has been chosen by thousands of customers including Lockheed Martin, HP, IBM, Shell, etc. Based on the TWAIN specification, Dynamic Web TWAIN is mostly used with scanners. In the past few years, we received many requests from our customers for a similar control for webcams. Therefore we introduced Dynamic Webcam SDK in 2012 which has almost the same feature set as Dynamic Web TWAIN but was meant for webcams. After that, a few of our customers asked us to support both scanners and webcams in their web applications. With that thought in mind, our R&D team worked out ImageCapture Suite, which is a browser-based TWAIN & DirectShow Webcam Capture SDK.

How to upgrade from Dynamic Web TWAIN to ImageCapture Suite?


ImageCapture Suite provides two acquisition modules – a Scanner Module and a Scanner+Webcam Module. If you only need support for TWAIN scanners, the Scanner Module is enough. And your current Dynamic Web TWAIN licenses (if any) are compatible with ImageCapture Suite. Otherwise, you can contact sales[at]dynamsoft.com to upgrade your license.

Meanwhile, if you need a 1D/2D barcode Reader or an OCR SDK for your web application, you can purchase the corresponding licenses here.
