I am making a metro app which uses the MediaCapture API to display a custom camera interface. I also want users to be able to manually adjust values such as saturation and individual RGB components, however I cannot figure out how to do this (the API provides controls for brightness, contrast, hues, etc. but not access to the individual RGB components of each pixel). I understand I can make a C++ DirectX runtime component for image filtering, but that component would not be adjustable with a slider, so it doesn't really help me. How can I allow users to adjust properties of a camera preview not provided by the API?
All help is greatly appreciated and I always accept an answer!

This API is for every camera,
if you want additional customize function you need MFT.
please check this video from 0:05:00, it explain how to achieve what you want and more about other camera options.
And MSDN about Metro style Device Apps :http://msdn.microsoft.com/en-us/library/windows/hardware/hh833796.aspx
Hope it helpful.

The video and examples are with regards to third-party cameras. I want to know how to apply a varying level of an effect (e.g. saturation) on the output of the default webcam. This sample illustrates sort of what I want to do (the problem with this sample is that the effect is not adjustable).

I'm not sure about it, I'll involve someone who familiar with this camera API.
Please wait for a few days.

Just to clarify,
You are developing the app for your camera. Is that correct?

Tuesday, August 07, 2012 4:20 PMNo. I am developing an interface for whatever the default camera is. I have taken a look at the MFT0 sample, and while it does help understand how MFTs work, it doesn't explain how to apply an adjustable level of a transform, such as is needed in my case.
