logitech 4000 image capture software (hopefully sdk!!)

[todd:: pro5pro.com]

hello,
i have a very tough problem.
i want to capture images from my newly purchased quickcam 4000 using
my own software written in Visual Basic 6.0
i have obtained the ezVidCap.ocx activex control and it works.
but... i cannot set it to grab single frames at full (1.3mpxl)
resolution, only 640x480.
i assumed that i would easily be able to capture still images at the
advertised resolution, but no.
has anyone had any luck with this????!!!!
i'm really desperate, since my app won't work at 640x480.
i don't need high frame rates or anything... 2hz would be fine.

any help is greatly appreciated. please respond to this newsgroup,
since my email is very shaky right now due to spam overload.

thx,
todd

AFAIK the maximum resolution for the QuickCam 4000 is 640x480.
It's possible to interpolate in order to get a bigger image, but it's
just software interpolation -- you don't get a better quality picture.
I don't know where exactly the interpolation is done, but you can do
your own, the result won't be very different from the one you'd have
had with Logitech software.
Look for "bicubic interpolation" in google.
