video acquisition from frame grabber

[rui0632]

I wanted to acquire image from a video camera which only has analog output. To do that, I used a framegrabber, called :"Hauppaugel analog video giditizer".

However, as I can see from the list, the framegrabber provides image with YUY 2 format and in the list of my Labview vision module, I could not find such type.

I have written a code for acquiring image which works fine with normal web cameras. however, when I want to use it for acquiring the image from frame grabber, it gives following errors:
1. Error code: 1074396120 Not an image
2. Error code: 1074396015 Cannot connect to camera, it may be in use.

I guess it has something to do with the formats of the picture, but I really don't have experience with that. Could you help me out? The code is attached.

I lookforward to your advice and thank you in advance for the help.

Hello,

First, you have to know that your camera must be Direct Show, otherwise, you won't be able to use it in LabVIEW.

If it is compatible, then you will be able to grab image using IMAQ USB, but keep in mind that this set of VI is no longer supported as IMAQdx is fully compatible with DirectShow cameras, and much better than IMAQ USB.
