如何以编程方式更改 Windows Mobile 上的相机曝光?
我需要从程序内部更改(降低)相机曝光。
我发现的记录的 API (DirectShow) 似乎不起作用。
任何帮助表示赞赏。

The documented API I found (DirectShow) don't seem to work.
Any help is appreciated.

您可能将曝光属性设置为错误的值,或者您的设备可能根本不支持 DirectShow 接口。请参阅这篇文章(可能与您的设备相关,也可能不相关):

您所在的特定设备using 可能有一个可以访问的 API,而不是使用 DirectShow。您的目标设备是哪些?
You may be setting the exposure property to the wrong value, or your device may simply not support the DirectShow interface. See this article (which may or may not be relevant to your device):

The specific device(s) you're using may have an API that you can access instead of using DirectShow. Which devices are you targeting for this?
如果您专门针对高端 Samsung Windows Mobile 手机,他们的 Windows Mobile SDK 具有高级相机 API,可让您设置 ISO 速度。可以通过 http://innovator.samsungmobile.com 获取。
If you're specifically targeting higher-end Samsung Windows Mobile phones, their Windows Mobile SDK has an advanced camera API that enables you to set ISO speed. It's available at http://innovator.samsungmobile.com.
