how to capture web_cam image using python?

how to capture web_cam image using python(raw python) without using any library like cv2 or pygame.

it would be great if anybody know the trick how to capture image using only raw python. advance thank you so much.

I tried using the VideoCapture extension, but that didn't work very well for me. But the problem is that it's a bit slow with resolutions 320x230, and sometimes it returns None for no apparent reason.

you also need this:

pip install opencv-python

To Save image press space

Try This:

import cv2

cam = cv2.VideoCapture(0)

cv2.namedWindow("test")

img_counter = 0

while True:
    ret, frame = cam.read()
    cv2.imshow("test", frame)
    if not ret:
        break
    k = cv2.waitKey(1)

    if k%256 == 27:
        # ESC pressed
        print("Escape hit, closing...")
        break
    elif k%256 == 32:
        # SPACE pressed
        img_name = "opencv_frame_{}.png".format(img_counter)
        cv2.imwrite(img_name, frame)
        print("{} written!".format(img_name))
        img_counter += 1

cam.release()

cv2.destroyAllWindows()

You can download "pygame‑1.9.2a0.win32‑py3.4.exe"

import pygame
import pygame.camera
pygame.camera.init()
cam = pygame.camera.Camera(0,(640,480))
cam.start()
img = cam.get_image()
pygame.image.save(img,"filename.jpg")
