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()
by use Pygame 3.4

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")
cv2orPyGame. I'm not sure but maybeffmpegcan also readweb_cam. And if you have problem with speed then you should first check if you have the same problem with other tools - maybe problem is camera, not Python.
