Why does a Quickcam not correct for brightness?
The Logitech Quickcam has a software video driver. When the preview screen of the Quickcam is not visible, the driver software supplied by Logitech is not invoked. This means that if the Quickcam is configured for auto-brightness, if the preview window is not shown the auto-brightening will not happen. The preview window is not visible if Webcam32 is minimized, obscured by another window or hidden by a screen saver or simply switched off. This is a known limitation of the Quickcam camera and there is nothing within Webcam32 that can currently assist. The solution is to enable the “Update when Hidden” option under video preferences.
