Streaming images with HttpResponse?

I have this simple app that I opens webcam and processes the frames using OpenCV. In my views.py I have the following code:

    def processImage():

    

    while True:

        

        rval, frame = settings.CAP.read()  //Read frames from webcam

        gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)         //Make frame grayscale

        pil_img = Image.fromarray(gray)  

        

        response = HttpResponse(mimetype="image/png")

        pil_img.save(response, "PNG")

        

        return response

Although there is a while loop the function runs only once because it is broken by "return response". How could I change the code to make it run constantly?
