Windows Vista recommended to be at Service Pack 2.
Windows 7 recommended to be at Service Pack 1.

How do I know if I have the most recent version of LuCam software?

The most recent version of the LuCam software is always posted on our website. You can determine the version you are working with by opening the LuCam Capture's application's About box. This box displays the software versions for the overall LuCam software, the LuCam API, the device driver, the camera firmware and its FPGA load.

What applications are available for USB cameras with the installation of Lucam software?

Other than the Lucam Capture application, many useful sample applications are accessable in the following folder through the Lucam software: C:\Program Files\Lumenera Corporation\LuCam Software\SDK\Executables. These sample applications are the compiled executable versions of the source code samples included with the purchase of the Lumenera SDK. They demonstrate the use of the many LuCam API functions. As sample executables, these programs are provided for demonstration, but not all functions are supported on every camera model. A detailed list of the executable sample applications can be found in the last section of the USB Camera User’s Manual. Of the samples available, these are the most commonly used:

1) AVISample - save short AVI (Video) file and playback the saved AVI (video) file.
2) CaptureToFile - save captured image directly to your PC hard disk.
3) Framerate - read the various available frame rates with different ROI, binning/subsampling settings.
4) GetRanges - read and write the camera properties and get their value ranges
5) Snapshot – demonstrates camera snapshot functionality with or without hardware trigger
6) AutoLens – provides control for the Canon EF lenses used with the Lw11059

Where can I find the Lumenera Camera User Manual?

An electronic copy of the LuCam User Manual is installed with the LuCam software. The document is in Adobe Acrobat (PDF) format. It is located in a Documentation folder where the LuCam Software was installed. Typically this is the location:

C:\Program Files\Lumenera Corporation\LuCam Software\


Can I pull multiple video streams from the camera?

No. This camera will only support one video stream to one application at a time. However, you can have more than one application access the camera at a time.

How do I control the exposure time?

The exposure time can be controlled through the LuCam API. The LucamSetProperty() function with the LUCAM_PROP_EXPOSURE property provides the mechanism to control the exposure of the camera when in video mode. In snapshot mode you can set the exposure parameter of the LUCAM_SNAPSHOT structure.


How do I control the frame rate after I have configured the camera?

The camera supports a parameter "frame rate" (set through LuCam Set Format) that allows the user to set the value to a rate that is below the maximum. The actual frame rate will be set to the nearest frame rate that is equal to, or below, this desired frame rate.

How can I turn off my USB 2.0 camera?

The USB 2.0 camera will work with your computer's power management scheme. The camera will turn off when your computer turns off or sleeps and turns on when the computer is awake. If you want to turn off the camera without turning off the computer or putting it to sleep you will need to unplug the USB 2.0 cable and the external power supply (if used) from the camera.


What is the maximum number of USB 2.0 cameras on a single USB 2.0 bus?

In theory, you can have up to 127 USB 2.0 devices on one USB 2.0 bus. This value includes all hubs required to connect all the other USB 2.0 devices on the bus. Assuming you wanted to connect as many cameras as possible and you assume that each hub has 4 ports, you would be able to connect, in theory, up to 94 cameras using 33 hubs. In practicality though, we do not recommend connecting more than 4 at a time as the performance of each camera will be reduced with each camera.

I only have two USB 2.0 ports available on my computer. How can I connect more than 2 cameras on the same bus?

There are two options. Either you can purchase a USB 2.0 Adapter card for your computer with extra USB 2.0 ports or you can purchase a USB 2.0 hub.

Do you provide a longer USB 2.0 cable with your cameras?

The standard cable we provide is a 6' (2m) cable. We can provide a 10' (3m) or 15' (5m) cable upon request. Please contact if you require more information on ordering these cables


My USB 2.0 camera is not recognized by the system and not listed in Device Manager. What should I do?

If the camera does not show up in the Windows Device Manager, the cause could be one of the following:

  • Confirm that the camera has the correct DC voltage if it is a camera that requires external power (most newer models include over-voltage protection that will disable the camera circuitry when power input exceeds the required voltage - however, older models do not include over-voltage protection. Care must be taken to ensure that the correct input voltage is supplied. The requirements are always indicated on the camera body. Many models function with only the USB bus power.
  • Verify that the USB cable is not faulty. Test the camera with another USB cable.
  • Test the camera by connecting it into another USB port, or on another PC. If the camera is detected by host, an entry will appear in the Windows Device Manager – regardless of whether the device driver is loaded on the computer.
  • Refer to the Troubleshooting Guide for further suggestions.

Why does Windows Device Manager incorrectly list my Lumenera camera, or displays an exclamation mark beside the device?

  • This describes the situation that occurs when the correct device drivers are not loaded to the camera by the operating system. It may occur if the camera is connected to the PC before the software and device drivers have been installed. Lumenera camera device drivers are now signed and compliant with Microsoft requirements, so device drivers should load automatically whenever the camera is connected to a PC where the device drivers are resident.
  • Refer to the Troubleshooting Guide for further suggestions.

Why is my image darker in the corners?

This issue, known as vignetting, happens when the lensing used is too small for the camera's sensor. Make sure that you use the proper lens/optics for the camera. Your camera's datasheet will state the size of the sensor used so that you can properly match your lens/optics.

What settings have an impact on the camera frame rate of streaming images from the camera?

There are a few reasons why you cannot get the advertised frame rate.
The selected exposure time limits the frame rate. Make sure that the exposure time < 1/desired frame rate.
There is not enough computer resources to keep up with the current camera data rate. You will need to minimize the resource usage or operate the camera on a faster computer.


When I am debugging an application in Visual Basic and stop the debugger while the application is running, I get a error in Visual Basic and it closes down. How can I correct or avoid this issue?

This is an issue with any development environment, not just Visual Basic. The issue is that the DirectShow filters are still trying to stream to the preview window but it is no longer available. What you need to do to avoid this issue is to stop the stream and close the preview window either by closing the preview dialog box or by calling LucamDestroyDisplayWindow(), if it was created by the LuCam API.

DirectX and/or DirectShow

Do you support DirectX and/or DirectShow?



What lenses do your cameras support?

Our cameras support any C-Mount based lens. You can also order cameras with either CS-Mount or microlens mount.

I/O Port

How can I synchronize an external event with the exposure period of this camera in the streaming video mode as well as in the snapshot mode?

In video mode you can use the Start Of Frame (SOF) signal that is generated by the camera to synchronize a strobe. This pulse is generated at the end of the previous frame prior to exposing the next frame. In snapshot mode you can use the strobe output of the camera.

Apple O/S

Do you have a USB 3.0 or USB 2.0 driver for Mac?

A Mac interface is available for the INFINITY camera models only. The microscopy cameras are supported by INFINITY ANALYZE for Mac, or through an ImageJ plug-in.
