Here is a step by step guide on accessing USB Camera(Webcam) with Python and Python Imaging Library(PIL).
(For Windows platform).1. Download and install Python 2.5 from here. You can choose the folder C:\Python25 for installation.
2. Download the zip file Videocapture from Sourceforge here.
Open the zip file and copy the vidcap.pyd in DLLs to C:\Python25\DLLs and files in Lib to C:\Python25\Lib folders respectively.
The installation is over. Now you are ready to access the USB camera.
4. Open the GUI for Integrated Development Environment(IDLE) by Start -> Programs -> Python 2.5 > IDLE (Python GUI).
You can take a snapshot by executing three command lines only:
>> from VideoCapture import Device
>> cam = Device()
>> cam.saveSnapshot('Snap.jpg')
Snap.jpg file will be stored in the root folder C:\Python25.
It can be viewed by MS Paint.
PIL - Python Image Libray is a collection of files to manipulate images.
