如果您有扫描仪，您可能知道TWAIN标准。如今，大多数扫描设备都支持TWAIN驱动程序，因此用户可以在扫描图像时享受无忧的体验。在本文中，我们将介绍TWAIN是什么以及如何在 Windows 10计算机上安装 TWAIN 驱动程序。^{(install TWAIN driver on Windows 10)}

什么是TWAIN，它如何^(How)使图像扫描变得容易？

TWAIN是扫描设备的标准。它于 1992 年首次发布，适用于在Windows和Macintosh操作系统上运行的计算机。TWAIN的发布使图像扫描过程变得无忧无虑。在TWAIN之前，用户必须选择一个特殊的应用程序从扫描仪接收图像，然后将图像保存到磁盘。之后，他们可以在他们选择的软件中打开该图像以使用。

使用TWAIN，无需将扫描的图像保存在磁盘上。TWAIN在图像处理软件和扫描仪、数码相机等设备之间建立了通信链接。这使用户可以直接在他们用于图像处理的软件中打开扫描的图像，前提是他们在系统上安装了TWAIN驱动程序.

如何在 Windows 10 上安装TWAIN驱动程序^(TWAIN)

每个品牌都开发了自己的TWAIN驱动程序来支持该品牌的扫描仪。您可以从您正在使用的扫描仪品牌的官方网站下载驱动程序。^{(download the drivers from the official website of the brand)}在这里，我们将描述在Windows 10上为五个最受欢迎的品牌安装TWAIN驱动程序的过程：

How to install TWAIN driver on Windows 10

If you have a sсanner, you probably knоw about the TWAIN standard. Today, most scanning devices support TWAIN drivers so that users can enjoy a hassle-free experience while scanning the images. In this article, we will describe what TWAIN is and how you can install TWAIN driver on Windows 10 computers.

What is TWAIN and How did it make the image scanning easy?

TWAIN is a standard for scanning devices. It was first released in 1992 for the computers running on Windows and Macintosh operating systems. The release of TWAIN has made the process of image scanning hassle-free. Before TWAIN, users have to select a special application to receive the image from the scanner, then save the image to the disk. After that, they were able to open that image in the software of their choice to work with.

With TWAIN, there is no need to save the scanned image on the disk. TWAIN establishes a communication link between the image processing software and the devices such as scanners, digital cameras, etc. This lets users open the scanned image directly in the software which they use for image processing, provided they have installed a TWAIN driver on their system.
