Advanced Functionality
Once you are comfortable with the basic operations, you can explore advanced functionality offered by the Raspberry Pi Camera.
Picture Quality Adjustments
You can improve your image’s quality using various camera parameters such as exposure, brightness, and contrast. Here are some command-line options to consider:
- Brightness: `-br` to set the brightness (0-100).
- Contrast: `-co` to adjust contrast (-100 to 100).
- ISO Settings: Use `-ISO` to set ISO values for better low-light performance.
Using Python For Capture Automation
For those interested in automating captures or incorporating the camera into more extensive projects, you can use Python with the Picamera library:
-
Install the PiCamera Library:
sudo apt-get install python3-picamera -
Write a Simple Python Script:
Here’s a basic example:
“`python
from picamera import PiCamera
from time import sleep
camera = PiCamera()
camera.start_preview()
sleep(5) # Camera warm-up time
camera.capture(‘/home/pi/image.jpg’)
camera.stop_preview()
“`
This script initializes the camera, waits for 5 seconds, and then captures an image. It will help you to understand how to control the camera programmatically.
