Why does my front facing camera light up red?


forgive me if weird/stupid question, i've noticed on iphone 4, when i'm in phone call or using google voice app, front facing camera lens turns red. didn't think of @ first, it's kind of creeping me out now. ideas of why this?

edit: ok, feel little idiotic know it's proximity sensor (i think?). anyway, read online in forums, seems people upset it, i'm not sure why bad thing , means? can explain?
