I can't stand just a simple Nope without an explaination:-). Gamma correction
is nonlinear amplification applied to the video signal's amplitude to compensate
for the fact that television picture tubes are nonlinear EG: twice as much 
video level doesn't make the picture twice as bright. Correction for this is
always applied in TV cameras (Commercial ones, I don't know about the cheap
home ones). The ratio between R G and B signals when mixed to produce monochrome
is something else entirely. The ratio is something like 11% Blue, 59% Green and 
the rest Red. These are not necessarily the CORRECT figures as I don't have
them right here. If anyone really needs to know, I can look it up later.
