QImaging Hardware

Troubleshooting QImaging Devices

If you are having trouble using the Image Acquisition Toolbox™ software with a supported QImaging® camera, follow these troubleshooting steps:

  1. Verify that your image acquisition hardware is functioning properly.

    For QImaging devices, run the application that came with your hardware, QCapture, and verify that you can receive live video.

  2. Select Start > Programs > QCapture Suite > QCapture.

  3. In QCapture, select Acquire > Live Preview to test that the hardware is working properly.

  4. With previous versions of the Image Acquisition Toolbox, the files for all of the adaptors were included in your installation. Starting with version R2014a, each adaptor is available separately through MATLAB® Add-Ons. In order to use the Image Acquisition Toolbox, you must install the adaptor that your camera uses, in this case, the QImaging Hardware support package. See Image Acquisition Support Packages for Hardware Adaptors for information about installing the adaptors.

  5. If your hardware is functioning properly, verify that you are using a hardware device driver that is compatible with the toolbox.


    The Image Acquisition Toolbox software is compatible only with specific driver versions provided with the QImaging software and is not guaranteed to work with any other versions.

    • Find out the driver version you are using on your system. To learn how to get this information, see Determining the Driver Version for QImaging Devices.

    • Verify that the version is compatible with the Image Acquisition Toolbox software. For the correct driver information, check the list of supported drivers on the Image Acquisition Toolbox product page at the MathWorks Web site (

    If you discover that you are using an unsupported driver version, visit the QImaging Web site ( to download the correct drivers.

Determining the Driver Version for QImaging Devices

To determine the QImaging driver version you are using, run the QImaging QCapture utility.

Select Start > Programs > QCapture Suite > QCapture, and then select Help > About to see the driver version number.
