how to add a video option to capture image

[malavi]

Am using a CCD camera to capture the image. I have to add the option to capture video(live )image so that i can focus and adjust the image and then capture it for processing. Is there any option. I searched the SDK along with the camera but could not find.

I assume you want to adjust the focus seeing the streaming in labview (correct me if otherwise). You can easily do this using a "acquire" inside a while loop. Use a capture button to exit the while loop and save/process the captured image.

Hi Malavi,

Did you try the IMAQ grab vi in the vision and motion pallete. This vi continuously acquires images at a rate specified in MAX. Try the vi in the NI example finder>>toolkits>>vision and motion.

I could not find the video and motion pallete in ver7.1. I found just blank blocks for the above. Can  u help me

Hi Malavi,

If you are seeing blank blocks in the pallete, this means you do not have the IMAQ or IMAQ dx drivers. Please make sure they are installed.

Hopefully it would work then.

Best Regards,
