Initially , the cam was very crisp and clear resolution. Now , has rough textured appearance. resolution sucks. Is the USB cable / connection to blame? Or has Cam been damaged by some impact ? post:ask.metafilter.com,2005:site.27236 Mon, 14 Nov 2005 21:17:21 -0800 Agamenticus webcam http://ask.metafilter.com/27236/Webcam-grainy-images#428778 Add more light? comment:ask.metafilter.com,2005:site.27236-428778 Mon, 14 Nov 2005 21:25:16 -0800 smackfu http://ask.metafilter.com/27236/Webcam-grainy-images#428785 You've likely checked this, but have any software settings for image resolution/quality been modified by someone? comment:ask.metafilter.com,2005:site.27236-428785 Mon, 14 Nov 2005 21:33:30 -0800 NucleophilicAttack http://ask.metafilter.com/27236/Webcam-grainy-images#428786 Try turning the focus ring around the lens comment:ask.metafilter.com,2005:site.27236-428786 Mon, 14 Nov 2005 21:34:00 -0800 weapons-grade pandemonium http://ask.metafilter.com/27236/Webcam-grainy-images#428810 Aperture (if it has one) might be jammed, hence not enough light and it gets noisy by trying to crank up the gain in software. comment:ask.metafilter.com,2005:site.27236-428810 Mon, 14 Nov 2005 22:32:20 -0800 polyglot http://ask.metafilter.com/27236/Webcam-grainy-images#428828 Clean the lens, too. You can get a cloth to do so from a camera store. If it's a really cheap webcam, then the lens is plastic, and will degrade all on its own over time. comment:ask.metafilter.com,2005:site.27236-428828 Tue, 15 Nov 2005 06:19:08 -0800 mendel http://ask.metafilter.com/27236/Webcam-grainy-images#429805 Have tried all of these things. I'm thinking it's an internal problem . Seems to be clean lens, ring /focus works/light bright enough. Next I'm moving it to another computer to replicate issue. comment:ask.metafilter.com,2005:site.27236-429805 Tue, 15 Nov 2005 20:50:29 -0800 Agamenticus
