Hamamatsu Hardware

If you are having trouble using the Image Acquisition Toolbox™ software with a x Hamamatsu digital camera, follow these troubleshooting steps:

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

    • Make sure that your camera is plugged into the IEEE® 1394 (FireWire) port on your computer and is powered up.

    • Run the application that came with your hardware and verify that you can acquire video frames. Use the exAcq.exe application, available from Hamamatsu.

  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 MATLAB® Add-Ons. In order to use the Image Acquisition Toolbox, you must install the adaptor that your camera uses, in this case, the Hamamatsu Hardware support package. See Image Acquisition Support Packages for Hardware Adaptors for information about installing the adaptors.

  3. Make sure you specified the hamamatsu adaptor when you created the video input object. Some IEEE 1394 (FireWire) cameras can be accessed through either the dcam or winvideo adaptors. See Creating a Video Input Object for more information about specifying adaptors.

  4. Verify that you are using the correct hardware device driver that is compatible with the toolbox. The Image Acquisition Toolbox software is only compatible with specific driver versions provided by Hamamatsu and is not guaranteed to work with any other versions.

    • Find out the driver version you are using on your system.

    • 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 Hamamatsu Software API Support page ( to download the correct driver that is supported by the toolbox, if it is available there. If it is not available, please contact Hamamatsu to obtain the correct driver.
