When a webcam is connected to a Windows Vista-based computer, some default values are not regained after you click Default in the webcam’s Properties dialog box
Consider the following scenario. You connect a webcam to a Windows Vista-based computer. In the webcam’s Properties dialog box, you click Default on the Video Proc Amp tab or on the Camera Control tab. In this scenario, you may encounter the following problems:
- On the Video Proc Amp tab, you click to clear the Auto check box for the White Balance setting. Then, you set a value that you want. If you click Default, the default white balance value is regained. However, the Auto check box is not selected.
- On the Camera Control tab, the value of the Low Light Compensation check box does not change after you click Default. This occurs regardless of whether the check box was initially selected or not.
