IMAQdx includes a utility VI that can be used to programmatically change the driver associated with a camera. You can use this VI to switch the drivers associated with the camera programmatically.

Even the core LabVIEW products contain capabilities for displaying, loading, and saving images in a variety of formats. Unfortunately, at a moment of time, LabVIEW only inherently supports expensive hardware based capture devices, leaving image capturing and processing out of the hands of low-budget users. This functionality opens up a number of possibilities for the augmentation of collected data by images. For example, webcam images can be embedded in front panels for monitoring remote hardware or even for remote experimentation. As another example, webcam images can be processed for information that can then act as a trigger for other data collection operations. Philipp Spitzer has contributed an updated version of the LabVIEW webcam library that remedies some crash bugs version 1. These devices include USB cameras, webcams, microscopes, scanners, and many consumer-grade imaging products.

It is designed to work with Micorsoft WDM streaming drivers. I am not very adept with this way of doing things. I think there my not be a manufactures filter and what I am getting is some default filter. The card is capturing a full X, but Labview is reducing it to X Default. I have to have the full X Here is what they said to my complaint:. The WDM drivers are written to comply with Microsoft Windows Media Encoder requirements, your DirectX application must ask or set the drivers for the resolution that you require to be captured. If this request is not made, or your application is unable to make such request then the default setting within the registery is x, hence input signals low or higher in resolution could get scaled up or down to x Does anyone know how to make a direct show filter? Or how to set the default size in the registery? This is what I am thinking.

See the information below to programmatically set your camera attributes in LabVIEW and in text-based languages. Note : Some attributes can not be set while acquiring, for example, the width and height of the image. You can use the following code to identify what functions are writable before and while acquiring.
