If you are having trouble using the Image Acquisition Toolbox™ software with a supported QImaging® camera, try the following:
Install the Image Acquisition Toolbox Support Package for QImaging Hardware.
Starting with version R2014a, each adaptor is available separately through MATLAB® Add-Ons. See Image Acquisition Support Packages for Hardware Adaptors for information about installing the adaptors.
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 website (
If you discover that you are using an unsupported driver version, visit
the QImaging website (

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.
Select Start > Programs > QCapture Suite > QCapture.
In QCapture, select Acquire > Live Preview to test that the hardware is working properly.
Note that Qmaging hardware is supported only on Windows 8 and prior versions of Windows. It is not supported on Windows 10.
Make sure no other application is accessing the camera.
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.
