Colleagues, May be someone of you like me has this really old (but still working!!) webcam. I've made a small patch for spca501 chip based cameras. It has the following imrovements, features: 1. Brightness autocorrection; 2. Color autocorrection; 3. Brightness is changed by exposition time - not by color offsets; 4. Fixed gamma coefficients; You may download it here: http://d-n-korovkins.narod.ru/gspca_spca501/ Regards, -- Dmitriy
