I got a webcam and I'm running some algorithm on the received images to find movements in it. But, the automatic auto white balance is changing the excepted result of the pixels color variance. That's why I'm trying to disable it. Some one knows a way to get the web can image with out this automatic color balance or disable it ?

Click the desired webcam. Click the Video tab. Click Color Adjustment. Click the toggle to turn off Auto exposure.
Pale might mean the contrast level is too mild to make al lof it look washed out. Color correction would not be the pale factor. Just contrast and brightness which work together to produce good images.
If you are on Linux, you can test disabling automatic white balance using the uvcdynctrl command line utility. This is not a permanent solution, since these settings are reset every time the webcam is disconnected from the computer. As of OpenCV 2.1, configuring white balance is not supported using cv::VideoCapture::set(). Assuming this is still the case in OpenCV 2.2, you will need to use another library to configure your webcam and capture frames.
If you on Linux, you can see an example of using direct Video4Linux (V4L) syscalls to do this in one of my Github projects.
