推荐答案

如果您使用的是CameraCaptureUi，则无法自定义窗口所示。如果您只需要快速简便的相机捕捉，并且无论它看起来如何，这个API都是合适的。

If you're using the CameraCaptureUi then there is no way to customize the window shown. This API is suitable if you just need a quick-and-easy camera capture and it doesn't matter what it looks like.

如果相机是您应用的核心部分而您需要一个特定的用户界面或功能（即完整的应用程序窗口大小），然后你需要使用MediaCapture API在进程中实现自己的Camera UI。

If the camera is a core part of your app and you need a specific UI or capabilities (i.e. full app window size) then you'll need to implement your own Camera UI in-proc with the MediaCapture API.

基本相机应用程序示例将获得您开始朝着正确的方向实施自己的相机用户界面。请参阅https：//github.com/Microsoft/Windows-universal-samples/tree/master/Samples/CameraStarterKit 

The Basic Camera App sample will get you started in the right direction to implement your own Camera UI. See https://github.com/Microsoft/Windows-universal-samples/tree/master/Samples/CameraStarterKit

There is an existing UserVoice request to allow the CameraCaptureUI to run full screen: https://wpdev.uservoice.com/forums/110705-universal-windows-platform/suggestions/10440042-improve-cameracaptureui-on-windows-10-desktop

这是正在调查未来的Windows更新（创建者更新后）。由于CameraCaptureUI是由相机应用程序实现的，并且在应用程序的上下文之外运行，因此其窗口大小取决于底层的IPC管道，而不是直接由相机应用程序或您的应用程序控制的
。在更新低级别管道之前，CameraCaptureUI无法控制其窗口的大小。

This is under investigation for a future update to Windows (after the Creators Update). Because the CameraCaptureUI is implemented by the camera app and runs outside of your app's context its window size depends on the underlying IPC plumbing and isn't directly controllable by either the camera app or your app. Until that low level plumbing is updated there is no way for the CameraCaptureUI to control the size of its window.
