Capture resolution is cropping the cam (Read 734 times)

Capture resolution is cropping the cam
Apr 30th, 2006, 1:02am  
Hi,

I´m having a little problem with resolution settings.

My camera is 640x480, but I wan´t to capture at 320x240 to get a better performance, so:

 video = new Capture(this, "PCTV USB2 2821 Capture-WDM", 320, 240, 30);

The problem is that the output image I get is a crop of the 640x480, and not a identical resized image as I expected.

It´s pretty wierd cause if you center the camera in some subject it will bearly appear on the screen.

Is there a way to set the capture resolution directlly?

Might be the actual driver rather than Processing. I updated my Creative Live Pro driver and now it does the same thing as your whereas it never used to. If I use an irregular capture size I get this crazy robocop vision thing happening.

Tried it in version 92 - same grief. (68 won't even run anymore Sad)

Don't know if perhaps it might be the new Quicktime causing it.

I don't think it's the camera driver since I can capture in other enviroments correctly.

May be QTCap - I get wierd images using it...

Didn't figure out how to solve though..
