dinamic image

Hello all.

I have LV7.1 and IMAQ Vision 7.1.

Now I see the dynamic image from WEB-camera.

When I wanted to rotate image – I received  static image.

Question: May I transfer and control dynamic image from WEB-camera.

With respect

Aleksandr

Hello Aleksander,

How are you acquiring images from your WEB-camera?  Is it connected to your computer via USB?

How are you rotating your image?

What exactly do you mean by "dynamic" and "static" images?

What exactly do want to do when you say "transfer and control dynamic image from WEB-camera"?

Hello Allen H.

Yes, I acquire images from WEB-camera via USB.

Menu of “IMAGE” has functions: Mirror, Rotate and ets.

I see in LV  Image moving  (dynamic).

Then I added the function Mirror or Rotate. And Image didn’t move.

And I was forced add the delay 0.2sec.

When delay < 0.3 sec the Image isn’t changed on display.

When delay > 0.3 sec the Image is changed on display
Best Regards,

Aleksander,

Hello Aleksander,

Try creating a separate image buffer to store your post-processed image.  Since your acquired image and processed (symmetry, rotate, overlay) image are both being written to the same buffer, your acquired image may be overwriting the previously processed image.

I have attached your VI with this modification added.  I have also cleaned up the wiring.  When debugging, it is best to first organize your functions and clean up wiring.
