RASPBERRY PI CAMERA V2

All codes below start with:
from picamera import PiCamera
from time import sleep
however you can see few options depends on what you are looking for and your setup

Python code:

To test the camera copy the below command

from picamera import PiCamera
from time import sleep

camera = PiCamera()

camera.start_preview()
sleep(10)
camera.stop_preview()

If your preview was upside-down, you can rotate it with the following code:

To rotate the PiCamera copy the below command “//un-hash the needed rotation angel//”

You can rotate the image by 90180, or 270 degrees or you can set it to 0 to reset.

from picamera import PiCamera
from time import sleep

camera = PiCamera()

#camera.rotation = 90
camera.rotation = 180
#camera.rotation = 270

camera.start_preview()
sleep(10)
camera.stop_preview()

Save photos from the PiCamera is the most common use for the Camera Module

from picamera import PiCamera
from time import sleep

camera = PiCamera()

camera.start_preview()
sleep(5)
camera.capture('/home/pi/Desktop/image.jpg')
camera.stop_preview()

It’s important to sleep for at least 2 seconds before capturing, to give the sensor time to set its light levels.

You can find the photo on the Desktop. Double-click the photo to open it:

Save Video from the PiCamera

from picamera import PiCamera
from time import sleep

camera = PiCamera()

camera.start_preview()
camera.start_recording('/home/pi/Desktop/video.h264')
sleep(10)
camera.stop_recording()
camera.stop_preview()
