Hi every one.  
I need help, I am trying to find the brightest pixels in a video with a webcam, the idea is to aim with a laser pointer the wall and find the white pixels, it works, but the problem is than I need a completly dark room because the rectangle find every pixel with color…  
I am using:

zone.getColorBoundsRect(0x000000CC, 0x00FFFFFF, false);

I already tried to scan pixel by pixel, with getPixel(), but the process makes the computer very slow…  
if you have any idea…  
…  
thank you very much.
