Troubleshooting Windows Video Devices
If you are having trouble using the Image Acquisition Toolbox software with a supported
Windows video acquisition device, follow these recommended troubleshooting steps:
1
Verify that your image acquisition hardware is functioning properly.
For Windows devices, run the application that came with your hardware and verify
that you can receive live video.
You can also verify your hardware by running the detectDevices utility provided
on the MathWorks Supported Hardware Web page: http://www.mathworks.com/
products/imaq/supportedioWindows.html. Under “Supported Hardware – Operating
System – Windows,” on this page, click the link that says download and run the
detectDevices utility to install the utility.
If you can run the utility without encountering any errors, the toolbox should be able
to operate with your image acquisition device. If you encounter errors, resolve them
before attempting to use the toolbox with the device.
2
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 the Support Package Installer. In order to
use the Image Acquisition Toolbox, you must install the adaptor that your camera
uses, in this case, the OS Generic Video Interface support package. See “Image
Acquisition Support Packages for Hardware Adaptors” on page 4-2 for information
about installing the adaptors.
3
If your hardware is functioning properly, verify that you are using hardware device
drivers that are compatible with the toolbox.
• Find out the driver version you are using on your system. The Image Acquisition
Toolbox software is only compatible with WDM (Windows Driver Model) or VFW
(Video for Windows) drivers. Contact the hardware manufacturer to determine if
the driver provided with your hardware conforms to these driver classes.
