Rand, if setResolution doesn’t support it, my guess is that your driver doesn’t either. Does your webcam actually advertise that resolution?

If it’s not supported, I think upscaling using PIL would be the only option.

I have gone this far too.

But I need to set the webcam to a higer resolution like 1600×1200 or higher and the setResolution function does not work in videoCapture.

Any advice ?

Very nice, but I’m getting an error from the PIL Image.py script saying there is not enough image data. I can’t find my webcam right now so I’m using Fake Cam to use an avi file as a camera instead and AmCap is able to view it just fine. It’s 3am and people are sleeping so I don’t really want to go looking for my webcam ATM.

Here’s how to capture webcam images on Linux. :)

Worked for me, great, but I had to make a couple of changes

1. “from PIL import ImageDraw” instead of “import ImageDraw”, perhaps that’s due to a change in PIL.

2. Added an infinite loop until the image was read, because “getImage()” does not guarantee to produce an image, and freezes the program. I used the following instead of calling getImage from inside Brightness()

camshot = cam.getImage()
while camshot==None:
camshot = cam.getImage()

Thanks a lot for this.

This is really an amazing implementation. I’m using a cheap webcam and this does a fantastic job.

I have written some improvements to this script though. I added controls to rotate the image, and use some of PIL’s imagefilters to have some fun with your mugshot.

My goal is to build a Python app that duplicates (and may even work better) than Apple’s Photobooth. If anyone wants to see my improvements, just email me at webmaster@asporina.com

Hi
It looks very nice
I am trying to do the same in Ubuntu, but videocapture is for win32, do you know any Extension for Accessing Video Devices for python in linux?

thanks

A Linux version would be great! Any news on that?

I think you need some way to interact with Video4Linux2 then …
