A CCD cannot be tricked by illusions of perception, but it can certainly be 
tricked by variable refractive indeces created by varying air temperatures. 
For instance, a camera can be used to film a mirage. The heat of the day is 
essentially 'boiling' into the night air, causing turbulence similar to the 
water currents in a boiling pot. Where these different temperatures meet, 
light is bent by the difference in refraction and the satellite appears to 
wobble.
