Camera Active Window

The select-level channel parameter Camera belonging to the Camera Specification category declares the unique name of the camera feeding the channel.

Expert-level parameters constituting the Camera Timing category are automatically adjusted to a consistent set of values each time the Camera parameter is updated.

These values define the timing behavior of the signals issued or received by the camera as long as the video sequence is concerned. The camera timing parameters specify the temporal size and location of the Camera Active Window inside the scanning format.

The camera active window is a rectangular region for area-scan cameras and a linear region for line-scan cameras. By definition, the camera active window is the timing area where luminance data are due to be provided by the camera.

Occasionally, a user wishes to adapt the MultiCam operation to a non-officially supported camera. The recommended way to achieve this is to set the Camera parameter to a value specifying a supported camera having characteristics close to the targeted camera. The next step is to adjust a few timing parameters to reflect the actual behavior of this camera. The MultiCam system will automatically adapt all grabber-related parameters to acquire video frames adapted to the newly defined camera active window.
