i.MX35 How to change camera properties on WinCE

Hi there,

 

I'm actually developing an application that interacts with a camera device on my i.MX35. On WinCE the hardware access is realized with the Microsoft camera device driver interface:

Camera Drivers (Windows Embedded CE 6.0)

 

Up to now I'm able to change the resolution of the camera input. Now I'd like to change the saturation, brightness, ... as well. Unfortuately I didn't get it work. However I'm able to read and write those properties. My solution actually uses the CSPROPERTY_TYPE_GET / CSPROPERTY_TYPE_SET mechanism of the driver interface. Right here I use PROPSETID_VIDCAP_VIDEOPROCAMP for reading / writing the values:

CSPROPERTY_VIDCAP_VIDEOPROCAMP (Compact 2013)

 

As mentioned, I'm able to modify the settings. However, the camera input does not change. Does anybody of you have experiences with that? Are there additional settings to be changed in order to get the modifications active?

 

Any help would be appreciated.

 

Best regards,

Peter
