Example of impact of random noise on color image.

Since space, color, and time are the coordinate points built in ⟨ r , c , t ⟩ space, no margin of
noise occurs as a coordinate point itself. Therefore, error and defection of information of
the coordinate point occur in light intensity S at the coordinate point as a false signal, such
as moiré, spurious resolution, false color, color noise, blurring, and lag.
