import cv2
from PIL import Image, ImageDraw

if __name__ == "__main__":
    camera = cv2.VideoCapture(0)
    cv2.namedWindow("Camera")

    if not camera.isOpened():
        print("Camera coudn't be found.")
        exit(0)

    while True:
        status, img = camera.read()
        if status == False:
            print("Camera closed.")
            break

        key = cv2.waitKey(1)

        if cv2.getWindowImageRect("Camera")[0] == -1:
            break

        cv2.imshow("Camera", img)

    camera.release()
    cv2.destroyAllWindows()
