SIVP How to configure a webcam (disable auto focus or white balance)

[manuel.kuehner]

Hello. I want to get pictures from a webcam. I use SVIP (http://sivp.sourceforge.net/). So far I have no problems.

In my application it is very important that I get the 'raw' information. I do not want that the camera does an anutomatic white balance.

Is it possible to configure a camera this way?

In Matlab there are ways:

Matlab example:

Solution:
To turn off the face tracking feature for a videoinput object created in the Image Acquisition Toolbox 1.5 (R14) and later, perform these steps:

vid=videoinput('winvideo',1);
src=getselectedsource(vid);
src.TiltMode='manual';

Verify the above by previewing the video stream:

preview(vid)

To turn it back on, use the following setting:

src.TiltMode='auto'

With some versions of the Logitech drivers, other mode settings may also need to be set to manual in order to disable head tracking. For example ZoomMode and PanMode may also need to be set to manual. For example:


src.PanMode='manual';
src.ZoomMode='manual';
