Hi, This is not a cheese problem, but rather a problem with the driver for your webcam likely the autoexposure algorithm is not doing the right thing in your specific circumstances. Since getting autoexposure right in all circumstances is rather tricky, the best solution is probably to just turn it of. Do as root: yum install gtk-v4l And then start gtk-v4l, Expand the more properties expander, unselect auto matic exposure, and then manually adjust the exposure and gain to your liking. Please let me know if this fixes things. Thanks & Regards, Hans This has been further discussed by mail, and manually controlling the exposure seems to fix this, closing. |
