SwisTrack/Components/InputCamera1394

Description This component allows you to grab image from firewire cameras using the CMU driver. The output images are grayscale or color (RGB) images. As the CMU driver does only exist for Windows, this component is not cross platform. Input A firewire (1394A or 1394B) camera. Output Image:SwisTrack_ColorImage.jpg A grayscale or color (RGB) image. Parameters Camera Number Allows you to select the camera if there are multiple firewire cameras connected. Video Format and Mode Video Format (0..2) and Mode (0..7) allow you to select the desired input type from the camera. Beware that a conversion is automatically done to output only grayscale or RGB images. Thus, YUV format are not really interesting, except if it allows for an increased camera frame rate. The following table describes the different modes and formats. To check the available input types of you camera, you can use the 1394CameraDemo.exe that is shipped with the CMU driver, or check the camera datasheet.

To check the available frame rates of you camera, you can use the 1394CameraDemo.exe that is shipped with the CMU driver, or check the camera datasheet. Configuration Window Allows you to open a configuration window to modify other camera parameters of the firewire camera, such as the white balance, saturation, gain, etc. Note that not all cameras allow you to modify all these parameters.
