If you are having trouble using the Image Acquisition Toolbox™ software with a supported Windows® video acquisition device, try the following:
Install the Image Acquisition Toolbox OS Generic Video Interface Support
Package. It includes the necessary files to use the
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.
Confirm that another imaging application is not connected to the camera.
Confirm that the camera and its supported video formats are detected by
the standalone hardware detection utility
detectDevices.exe (64-bit), which is installed
where MATLABROOT is the MATLAB installation folder. For example:
The following is sample output when you run
detectDevices.exe in this folder:

Confirm that the camera is detected in other DirectShow compliant applications, such as VLC Media Player. Utilities such as GraphEdit or AmCap Sample, which are included with Microsoft Windows Software Development Kit (SDK), are also useful for troubleshooting DirectShow driver related issues.
Some camera and video capture hardware manufacturers provide DirectShow drivers that need to be installed in order to use the hardware with imaging applications on Windows. Make sure you install the 64-bit version of the DirectShow drivers, as MATLAB is a 64-bit application.
Some vendor-provided DirectShow drivers might need to be registered using a vendor-provided utility in order to use the hardware with imaging applications on Windows. Refer to the vendor-provided instructions.
