How to programatically change the camera exposure on Windows Mobile?

Question

I need to change (lower) the camera exposure from inside a program.

The documented API I found (DirectShow) don't seem to work.

Any help is appreciated.

Answer 1

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?

Answer 2

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.
