Thanks for the lighting tip really helped. But, we tried and launched the prototype of a 46 inch screen. Put the resolution of 1920x1080. The brakes were terrible. As we realized that the problem is USB bandwidth. If you reduce the resolution of the camera image to at least 1024, then in principle everything works fine, but still, the movements are very blurry. I would like to find a better option, and possibly more expensive. You may want to pay attention to camera Fire-Wire, or in more expensive solutions?
And I still do not understand why the camera which would support the format HD 1080p, so much the brakes on the maximum resolution. Despite the fact that the computer is the Intel Core 2 Duo 2.2 Ghz, and the processor is loaded only to 15 percent. Whether the problem is USB bandwidth?
