Claim 4:
5. The image compensation device of claim 4, wherein the array function P(x,y) of the reflective units is determined by an equation below:

P(x,y)=Σj=0h−1Σi=0w−1δ(x−whi,y−wvj)

where h is a number of reflective units in a lateral direction, w is a number of reflective units in a vertical direction, wh is an interval between the reflective units in an lateral direction, wv is an interval between the reflective units in a vertical direction, δ is a Dirac delta function, and x and y are coordinate values of each of the reflective units when a plane on which the reflective units are arranged is represented in a two-dimensional coordinate system.
