Windows Mobile: using phone's camera with C#
提问by VansFannel
I want to show the image that mobile phone's camera its taking on a control in a WinForm. The idea is that my application works like camera's program. I want to show the image like if the user is going to take a photo.
我想在 WinForm 中显示手机摄像头在控件上的图像。这个想法是我的应用程序像相机的程序一样工作。我想显示图像，就像用户要拍照一样。
How can I do that? Can I do that?
我怎样才能做到这一点？我可以这样做吗？
If you need more details ask me.
如果您需要更多详细信息，请询问我。
Thank you!
谢谢！

Not very sure what you need, but you may try using Microsoft.WindowsMobile.Forms.CameraCaptureDialog:
不太确定您需要什么，但您可以尝试使用 Microsoft.WindowsMobile.Forms.CameraCaptureDialog：
string originalFileName;
using (CameraCaptureDialog dlg = new CameraCaptureDialog()) {
dlg.Mode = CameraCaptureMode.Still;
dlg.StillQuality = CameraCaptureStillQuality.Low;
//dlg.Resolution = new Size(800, 600);
dlg.Title = "Take the picture";
DialogResult res;
try {
res = dlg.ShowDialog();
}
catch (Exception ex) {
Trace.WriteLine(ex);
return null;
}
if (res != DialogResult.OK)
return null;
this.Refresh();
originalFileName = pictureFileName = dlg.FileName;
}

I think you should program against the hardware directly using a sdk or something similar.
我认为您应该直接使用 sdk 或类似的东西对硬件进行编程。
Since programming against hardware directly is usually in c/c++ the sdk will probably be native. So either you probably have to use pinvoke and the unsafe keyword.
由于直接针对硬件进行编程通常是在 c/c++ 中，因此 sdk 可能是本机的。因此，您可能必须使用 pinvoke 和 unsafe 关键字。
But first you should find the way to access the camera, and since this is hardware dependant you can start on the website of the phone's manufacturere.
但首先你应该找到访问相机的方法，因为这取决于硬件，你可以从手机制造商的网站上开始。

Check SmartDeviceFramework from OpenNetCF.orghave some tools for PocketPC including capturing frames from Camera.

What you want is a preview, not the capture, which is far more difficult. The best (and maybe only) solution is to insert a DShow Filter into the filtergraph to pipe the preview window to where you want.
您想要的是预览，而不是捕获，这要困难得多。最好的（也可能是唯一的）解决方案是将 DShow 过滤器插入过滤器图中，以通过管道将预览窗口传送到您想要的位置。
COM is a bear in the Compact Framework, and DShow is tough no matter what platform you're on. There are some resources online, like the DShow.NET library at sourceforge, and Alex Mogurenko's blog, but nothing specific to creating a capture.
COM 是 Compact Framework 中的一员，而无论您在哪个平台上，DShow 都很难。网上有一些资源，例如sourceforge 上的DShow.NET 库和Alex Mogurenko 的博客，但没有专门针对创建捕获的资源。
There is a native capture sample in the WinMo SDK that would be a useful guide to getting you there.
WinMo SDK 中有一个本机捕获示例，它是帮助您实现目标的有用指南。
