The script below saves the images in the /home/pi/webcam directory, so create the webcam subdirectory first with: mkdir webcam You can write a Bash script which takes a picture with the webcam. Also try other webcams, but you'll get the best performance from the Raspberry Pi camera module. Some webcams are more reliable than others, but this sort of issue You may experience poor quality pictures with a USB webcam, such as this accidentally artistic piece: Now the picture is taken at full resolution with no banner. Which shows the following information: - Opening /dev/video0.Ĭorrupt JPEG data: 2 extraneous bytes before marker 0xd6 Now add the -no-banner flag: fswebcam -r 1280x720 -no -banner image3. Picture now taken at the full resolution of the webcam, with the banner present. jpgĬorrupt JPEG data: 1 extraneous bytes before marker 0xd5 The webcam used in this example has a resolution of 1280 x 720 so to specify the resolution I want the image to be taken at, use the -r flag: fswebcam -r 1280x720 image2. Note the small default resolution used, and the presence of a banner showing the timestamp. This command will show the following information: - Opening /dev/video0.Īdjusting resolution from 384x288 to 352x288.Ĭorrupt JPEG data: 2 extraneous bytes before marker 0xd4 Install fswebcamįirst, install the fswebcam package: sudo apt -get install fswebcam Basic usageĮnter the command fswebcam followed by a filename and a picture will be taken using the webcam, and saved to the filename specified: fswebcam image. Note that the quality and configurability of the camera module is highly superior to a standard USB webcam. Rather than using the Raspberry Pi camera module, you can use a standard USB webcam to take pictures and video on the Raspberry Pi. Documentation > usage > webcams Using a standard USB webcam
