Camera Manual Focus GUI Test with Picamera2 and Tkinter on Raspberry Pi

Today, we will be testing a manual focus GUI for a camera using Picamera2 and Tkinter on a Raspberry Pi. This GUI will allow users to manually adjust the focus of the camera for precise image capturing.

Getting Started

First, make sure you have the Picamera2 library installed on your Raspberry Pi. You can install it by running the following command:

sudo pip install picamera

Next, we will need to install Tkinter for creating the GUI. You can install Tkinter by running the following command:

sudo apt-get install python3-tk

Creating the Manual Focus GUI

Now, let’s create the manual focus GUI using Python code. Below is a sample code snippet to create a simple GUI interface for adjusting the focus of the camera:

    import tkinter as tk
    from picamera import PiCamera
    import time
    
    camera = PiCamera()
    
    def update_focus():
        camera.zoom = (0.5, 0.5, focus_slider.get(), focus_slider.get())
    
    root = tk.Tk()
    root.title("Manual Focus GUI")
    
    focus_slider = tk.Scale(root, from_=0, to=100, orient=tk.HORIZONTAL)
    focus_slider.pack()
    
    focus_button = tk.Button(root, text="Update Focus", command=update_focus)
    focus_button.pack()
    
    root.mainloop()
    

Testing the Manual Focus GUI

Now that we have created the manual focus GUI, let’s test it by running the Python script on the Raspberry Pi. You should see a slider that allows you to adjust the focus of the camera. Try adjusting the slider and clicking the “Update Focus” button to see the changes in focus.

With this manual focus GUI, you can now easily adjust the focus of your camera for capturing sharp images. Feel free to customize the GUI interface and add more features to suit your needs.

That’s it for our camera manual focus GUI test with Picamera2 and Tkinter on Raspberry Pi. Have fun capturing amazing images with your newly adjusted camera focus!
