Answer 1

A simple version of camera capture using OpenCv and Tkinter:

import Tkinter as tk
import cv2
from PIL import Image, ImageTk

width, height = 800, 600
cap = cv2.VideoCapture(0)
cap.set(cv2.CAP_PROP_FRAME_WIDTH, width)
cap.set(cv2.CAP_PROP_FRAME_HEIGHT, height)

root = tk.Tk()
root.bind('', lambda e: root.quit())
lmain = tk.Label(root)
lmain.pack()

def show_frame():
    _, frame = cap.read()
    frame = cv2.flip(frame, 1)
    cv2image = cv2.cvtColor(frame, cv2.COLOR_BGR2RGBA)
    img = Image.fromarray(cv2image)
    imgtk = ImageTk.PhotoImage(image=img)
    lmain.imgtk = imgtk
    lmain.configure(image=imgtk)
    lmain.after(10, show_frame)

show_frame()
root.mainloop()

You will need to download and install PIL...

UPDATE:

... and OpenCV for this to work.

To Install PIL, run the following command in your Terminal/Command Prompt:

pip install Pillow or python -m pip install Pillow

To Install OpenCV, run the following command in your Terminal/Command Prompt:

pip install opencv-python or python -m pip install opencv-python
