Now you just need to change camera parameters and drivers will perform actions needed to propagate these changes. All the parameters are available in PHP extension, for manual adjustment you may use parsedit.php (that you probably already use). If you open parsedit.php without any parameters it shows several links, including one that has parameters related to white balance. I'm not sure how well it will perform in linescan mode, but it is probably possible to adjust the parameters for satisfactory result. The problems with linescan mode (both white balance and autoexposure) could be related to different latency between changing parameters and histogram data available to the application. Andrey
