Demonstration of photo taking

Written a frame and put camera.py(written before) into video().

First frame

But there appears two windows: one is opencv.imshow and the other is tkinter’s frame. Find ways to merge the two windows into one.

video

OpenCV represents images in BGR order, however PIL represents images in RGB order, cv2image swap the channels.

imgtk converts image to a Tkinter-compatible photo image.

Next is to get a screenshot of the video after pressing a button. Code for adding a button:
