Step 1: Requirements Project camera

Step 2: Connect & Start Up

On the side of the Raspberry Pi 4B are two Micro HDMI ports. Plug the Micro HDMI cable into the left port, and the HDMI end into a monitor or display.
Connect a keyboard & mouse to the USB ports and finally insert the power cable into the USB-C port.

Your setup is now ready to start.
If the de Raspberry Pi Now you start up you will see a desktop on your monitor. When you start up for the first time, you have to set it up, but that is explained step by step.

Step 3: Connect Camera Module To Raspberry Pi

  1. First check if you Raspberry Pi is off.
  2. Then locate the module port (Figure 1).
  3. Gently pull up the plastic from the port.
  4. Then slide the camera ribbon into the port. Make sure you connect the cable on the right side (Figure 2).
  5. Push the plastic clip back into place.

Step 3: Start up the camera

Once you have connected the camera, start up the Pi.

Now we are going to activate the camera.

  1. Go to the main menu (Figure 4).
  2. Click on “Configuration”.
  3. Then you go to interfaces. And click Enable for the camera (Figure 5).

To make sure the camera is activated, we go to the terminal. In the terminal, type:

sudo apt raspi-config

Then you will see this screen (Figure 6). Click on the 5th step.

      Figure 6

      Then click on “P1 Camera”. You will then be asked “Would you like the camera interface to be enabled?”. Then click Yes (Figure 7).

        Figure 7

        Reboot you Raspberry Pi.

        Step 4: Control the camera module in the terminal

        Open the terminal.

        To save a desktop photo type:

        raspistill -o Desktop / image.jpg

        The photo will automatically appear on your desktop.

        You can determine the size of your image by using the rasp still command. You can follow this command -h en -w places to determine width and height.

        raspistill -o Desktop / image-small.jpg -w 640 -h 480

         

        Now you can make a video through the video.h264 commando.

        raspivid -o Desktop / video.h264

        Step 5: Control the camera module with Python

        You can also control the camera with the Python IDE. Go to main menu, to programming and open Python IDE (Figure 8).

        Figure 8

        The Python picamera library connects to your camera. For this reason, it is important that you save your file as camera.py. Save the file cannot on as picamera.py. If you save it under this name, the library cannot be found and your camera will not work.

        Put the code in your Python IDE. This program ensures that the film (5) continues to film for 5 seconds. You can adjust this, the camera must have a timer of at least 2 seconds. This way it has enough time to measure the light.

        from picamera import Picamera
        from time import sleep
        camera = picamera()
        camera.start_preview ()
        train (5)
        camera.stop_preview () Open the terminal

        Flip image
        If your image is reversed, you can adjust it by adding this code.
        camera = PiCamera ()
        camera.rotation = 180

        You can rotate the camera with 90, 180, Or 270 degrees. To reset the whole image use 0 degrees.

        see-though
        You also have the opportunity to film while you can still see what is happening on your screen. For this we create a see-through alpha level. Due to the sleep 5 function you only see a see-trough screen after 5 seconds. If you do not want this, you can remove the drag function.

        camera.start_preview (alpha = 200)

        De alpha number can be between the 0 en 255. The lower the alpha number the clearer your monitor is and the camera falls backwards.

        Take a picture
        To take a picture, add camera.capture () code.

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

        Add loop
        Now we add a loop so that 5 photos are taken in succession.
        camera.start_preview ()
        for i in range (5):
        sleep (5)
        camera.capture ('/ home / pi / Desktop / image% s.jpg'% i)
        camera.stop_preview ()

        The variable i counts how many times the code has been repeated in a loop, from 0 to 4. The photos are saved as image0.jpg, image1.jpg, and so on.

        Record video
        Adjust your code by capture ()  to delete. Then write start_recording () en stop_recording (). Your code should look like this:
        from picamera import PiCamera
        from time import sleep

        camera = PiCamera ()
        camera.start_preview ()
        camera.start_recording ('/ home / pi / Desktop / video.h264')
        sleep (5)
        camera.stop_recording ()
        camera.stop_preview ()

        Your camera first starts a preview, records the video for 5 seconds and then closes the preview.

        Step 6: Change photo settings / effects

        The python pic camera software contains a number of effects and configurations that allow you to adjust your photo / videos.

        Adjust resolution
        When you take a photo via your Pi, the resolution is automatically adjusted to the size of your monitor. The maximum resolution for photos is 2592 × 1644. For videos this is 1920 × 1080. The minimum resolution is 64 × 64.

        camera.resolution = (2592, 1944)
        camera.framerate = 15
        camera.start_preview ()
        sleep (5)
        camera.capture ('/ home / pi / Desktop / max.jpg')
        camera.stop_preview ()

        Add text
        You can add text to your photo with annotate_text.
        Your code looks like this:

        camera.start_preview ()
        camera.annotate_text = "Hello world!"
        sleep (5)
        camera.capture ('/ home / pi / Desktop / text.jpg')
        camera.stop_preview ()

        Text appearance
        To change the appearance of the text, add this text to the code:
        camera.annotate_text_size = 50

        Size text
        You can change the size of the text between 6 to 160 the default size is 32.
        You can change the color by color en import at the top of your program. After the import you can indicate the color. You can do this according to this code:

        from picamera import PiCamera, Color
        camera.start_preview ()
        camera.annotate_background = Color ('blue')
        camera.annotate_foreground = Color ('yellow')
        camera.annotate_text = "Hello world"
        sleep (5)
        camera.stop_preview ()

        Clarity
        To adjust the brightness we use camera.brightness. The standard brightness is 50 and you can adjust it between 0 en 100.

        Try it with this code:
        camera.start_preview ()
        camera.brightness = 70
        sleep (5)
        camera.capture ('/ home / pi / Desktop / bright.jpg')
        camera.stop_preview ()

        This code makes a loop. This loop adjusts the brightness and shows the brightness level via text.
        camera.start_preview ()
        for i in range (100):
        camera.annotate_text = “Brightness:% s”% i
        camera.brightness = i
        sleep (0.1)
        camera.stop_preview ()

        Adjust contrast
        Just like the brightness, you can also adjust the contrast:
        camera.start_preview ()
        for i in range (100):
        camera.annotate_text = “Contrast:% s”% i
        camera.contrast = i
        sleep (0.1)
        camera.stop_preview ()

        You can use camera.image_effect to use a specific effect in your photo.

        The effect options are:

        none
        negative
        solarize
        sketch
        denoise
        embossed
        oil paint
        Hatch
        gpen
        cake
        watercolor

        film
        blur
        saturation
        color swap
        washed out
        postise
        color point
        color balance
        cartoon
        deinterlace1
        deinterlace2

        The standard affect is none.

        Choose an effect and try it out:
        camera.start_preview ()
        camera.image_effect = 'colorswap'
        sleep (5)
        camera.capture ('/ home / pi / Desktop / colorswap.jpg')
        camera.stop_preview ()

        Repeat image effects
        Use case camera.IMAGE_EFFECTS to repeat all image effects.
        camera.start_preview ()
        for effect in camera.IMAGE_EFFECTS:
        camera.image_effect = effect
        camera.annotate_text = “Effect:% s”% effect
        sleep (5)
        camera.stop_preview ()

        You can use camera.exposure_mode to set the exposure to a specific mode.
        The available options are:

         

        off
        auto
        night
        night preview
        backlight
        spotlight
        sports

         

        snow
        beach
        very long
        fixedfps
        anti shake
        fireworks

        The standard mode is auto.
        Choose a mode and try it with this code:
        camera.start_preview ()
        camera.exposure_mode = 'beach'
        sleep (5)
        camera.capture ('/ home / pi / Desktop / beach.jpg')
        camera.stop_preview ()

        You can cycle through all exposure modes with camera.EXPOSURE_MODES, like you did for the image effects.

        Change white balance
        You can do the camera.awb_mode to set the auto white balance to a preset mode.
        The available options are:

        off
        auto
        sunlight
        cloudy
        shade

         

        tungsten
        fluorescent
        Incandescent
        flash
        horizon

        The standard is auto.
        Choose an automatic white balance mode and try it out:
        camera.start_preview ()
        camera.awb_mode = 'sunlight'
        sleep (5)
        camera.capture ('/ home / pi / Desktop / sunlight.jpg')
        camera.stop_preview ()

        You can cycle through all white balance modes with AWB_MODES like you did for the image effects.
