Raspberry Pi high quality camera project - capture still and video images
Python3 script to control the Raspberry Pi High Quality Camera module using a push button with the following features:
Three camera modes. Pressing and holding the button for 2 seconds cycles through each mode indicated by an LED:
- Mode 1 (default) - Still capture - slow flash
- Mode 2 Video capture - fast flash
- Mode 3 Safe shutdown - Raspberry Pi safe power off - solid on
Camera functions are controlled by short button presses:
- Mode 1 - Still capture - press and release button to capture an image
- Mode 2 - Video capture - press and release button to start video recording, press and release again to stop video recording
- Mode 3 - Safe shutdown - press and release button to perform Raspberry Pi safe shutdown
Clone the repository to your Raspberry Pi home directory:
git clone https://github.com/milnepe/pi-hq-camera.git
Before running the script enable the camera interface using the Raspberry Pi Configuration from the Preferences menu or raspi-config and reboot:
cd pi-hq-camera
python3 pi-hq-camera.py
To run the script automatically when the Raspberry Pi boots up install the systemd unit:
sudo cp hq-camera.service /etc/systemd/system/
sudo systemctl enable hq-camera.service
sudo reboot
By default images and video are saved to the following directories:
/home/pi/Pictures
/home/pi/Videos
This script has been designed to use DFRobot Gravity LED & Button modules. These modules can be safely connected directly to the GPIO header using the standard Gravity cables as below:
Warning - check that it is safe to connect any other type of module in this way as you may damage your Raspberry Pi
