Is there a way to use the final OpenCV image as a camera?

edit

please explain: "OpenCV image as a camera"

sure you can put some text onto the image before showing it

You can use opencv to capture images from a webcam and then annotate it with text. That's basic functionality and not complicated.

So you wanted to put timer in cv2.putText?

I am in good mood currently so i guess what he wants to do:

1. Grab periodically a frame from a webcam
2. Annotate it with some text
3. Show the image

Is this understanding correct?. If so do the following:

Create a timer thread. Use VideoCapture object to grab frame. Use putText to draw the text. Use imshow() to show the picture, Or serialize the image and show it in your application.
