Problem with changing the size of a webcam picture

 

Hi everyone, 

 

I am using a Logitech quickcam pro 9000 webcam with Labview 8.5 and XP.

 

 I have attached a very simple program where I just take a picture and save it to a JPEG file. I get a correct picture when I set the width and the height to 320x240 (see attached photo). When I set it to 640x480 the photo is wrong (see also attached photo). When I use the Logitech sofware, I can change from one to another without any problem.

 

Would anyone know what is the problem and how I could fixe this? My goal is only to be able to take 640x480 photo using Labview.

 

Had exactly the same problem with another logitech webcam . 

 

Thanks a lot.

 

 Regards,

 

 Marc
