First, read the English article below.

If your laptop has a built-in webcam as most do, you can easily take a photo. If not, however, you'll need to install a webcam on your computer before continuing. Click the Windows logo in the bottom-left corner of the screen. This will search your computer for the Camera app, which allows you to take a photo with any attached camera. It's a white, camera-shaped icon at the top of the Start window. Doing so will open your Windows Camera app. A light next to your camera should come on once the camera is on, and you should see yourself in the Camera app's window. You should see your photograph subject's image on the screen. This camera-shaped icon is at the bottom of the Camera app window. Doing so will take a photo and save it to your Windows computer's Photographs app.
