Windows下扫描仪WIA驱动的实现

摘要

Windows Image Acquisition (WIA) provides digital image acquisition service for Windows systems. WIA is one of the most important methods to obtain images for image acquisition devices. WIA supports the scanner to obtain images by MiniDriver or MicroDriver. This paper first introduces the general concepts and architecture of the WIA, and then on this basis, detailed introduces the realization of MiniDriver and MicroDriver. At last, some typical problems in the implementation process are analyzed. This paper based on Microsoft's MSDN literature, combined with the actual project experience, introduces the implementation and typical problem solutions of the WIA Driver, development has an important reference. It is an important reference for related developers.%Windows 图像采集（WIA）为Windows 系统提供数字图像获取服务，是图像获取设备获取图像的重要方法之一。WIA提供了MiniDriver和MicroDriver两种方式以支持扫描仪获取图像。本文首先介绍了WIA的一般概念和体系结构，然后在此基础上又分别详细介绍了MiniDriver和MicroDriver的实现，最后对实现过程中一些典型问题进行了分析。本文以微软MSDN文献为基础，结合实际的项目经验，提出了WIA Driver的实现思路及典型问题的解决方法，对相关的开发者具有重要的借鉴意义。
