OS05A20 5MP USB Camera (B)

Working with Windows PC

Test Software

Most current Windows 10 systems come with a built-in camera application. You can directly open this default Windows camera app for testing. If you are using Windows 7 or cannot find the camera application on your system, you can download and install the AMCAP test software we provide from the Resources and Documents.

Testing Steps

Windows Built-in Camera Application

Search for "Camera" and open the app.
Click the gear icon in the top-left corner to open the settings interface, where you can set the resolution for photos or videos.
Click the video or photo icon on the right to switch between recording and capturing modes.

Amcap Software

Download and install the Amcap software.
Click the "Options" menu, then select "Video Capture Pin..." or "Still Capture Pin..." to configure image and video parameters.

Working with Linux Embedded Board

Software Environment

On Linux embedded boards such as Raspberry Pi, Jetson Nano, and RDK series, most systems come with default support for the UVC protocol. You can use OpenCV for image preview testing. To properly preview the image, please connect a display to the board.

Testing Steps

Open a terminal and enter the following command to install OpenCV:
```
sudo apt-get install python3-opencv
```

Download the example and test.

wget https://files.waveshare.com/wiki/common/Usb_camera_examples.zip
unzip Usb_camera_examples.zip
cd Usb_camera_examples
sudo python3 Usb_camera_examples.py
