This a KDevelop project to make a control for the Logitech Quickcam Express. This program is compatable with the new v4l2 drivers on the 2.6.x kernel. There are only 4 controls that work. They are 1. Exposure 2. Gain 3. White Color Balance 4. Auto Gain. The last one is only on or off. Just untar the file. cd to the directory where the files were untared. Do the command ./configure then make then make install. The executiable will be put in your bin directory. Just give the command logitechcamctrl . That should do it.

我做的一个图像数据库，有用户管理功能，支持图像的添加查询等操作。自己做了图像报表功能（还不完善）。使用时候要在SQLserver中建一个对应数据库，参见程序。-I made an image database, user management functions and support the addition of image-search operation. Own statements function of the image (not perfect). Use the time to build an SQL server database counterparts, see procedures.

现在在vc上采集视频常用的方法有三：vfw，directshow，opencv ；今天我们首先做一下利用vfw的视频采集程序。 VFW(Video for Windows)是Microsoft推出的关于数字视频的一个软件开发包，VFW的核心是AVI文件标准。AVI(Audio Video Interleave)文件中的音、视频数据帧交错存放。围绕AVI文件，VFW推出了一整套完整的视频采集、压缩、解压缩、回放和编辑的应用程序接口(API)。由于AVI文件格式推出较早且在数字视频技术中有广泛的应用，所以VFW仍然有很大的实用价值，而且进一步发展的趋势。 　　在VC++开发环境中调用VFW和使用其它开发包没有什么不同，只是需要将VFW32.lib文件加入工程中，但在开放视频捕捉与压缩管理程序时需要其它软件硬件设置。VFW为AVI文件提供了丰富的处理函数和宏定义，AVI文件的特点在于它是典型的数据流文件，它由视频流、音频流、文本流组成。所以对AVI文件的处理主要是处理文件流。
