In this case, computer can do much faster than human, less than 1 ms. What I 
want to comment here is an observation I found. I'm not sure it's already 
discovered by people in the field of vision science. I have a venican blind 
on my window with the strip direction vertical. One dayI had the blind almost 
closed with an opening about several mm in each opening. I still can see 
people walk by pass my window about 20 meters away. It's in a cloudy day. 
Accidently I moved my head horizontally vertical to the blind strip 
direction. Then an amazing thing happened. The figure of the person  becomes 
a white profile in the background of surounding, like being cut off a piece 
of white paper. This seems indicate that human vision process involves 
several stages and seperate processes. When we see a person, first a parallel 
process register the shape of the person only. Only in later stages, we begin 
to fill in the details. When I moved my head, apparently there was not enough 
time for my brain to fill in the details of the figure. Thus, I only see a 
blank or white figure.
