Comment(by corbet):

 One other note: one clear way to clean up the image is to slow the frame
 rate a bit, giving the sensor more time to gather light for each frame.
 That's been supported on the ov7670 driver for a long time.  I'll attach
 another nasty little utility called "sfrate" that I use to play with this.
 It takes two parameters, being the numerator and the denominator of a
 fraction describing the frame time.  Defaults are 1 and 30, for a 1/30 sec
 frame time - 30fps.  Running something like "sfrate 1 15" or "sfrate 1 10"
 makes for a lower frame rate, but better image quality.
