You don’t need to explicitly copy the image to your PC.
After acquiring the image like in the following listing (taken form here)…
image, status = stream.wait_for(1000)
…the image is already in the RAM of your PC, so copying is completely done for you in the background. If you now want to write the image to your harddisk, you can do so by calling the save function:
image.save("C:/somewhere/on/my/harddisk/myImage.bmp")
I hope this answers your question
