4. [10 pt] Suppose that a flat area with center at (xo, yo) is illuminated by a light source with intensity distribution i(x, y) = Ke-[(x−xo)²+(y—yo)²] Assume for simplicity that the reflectance of the area is constant and equal to 1.0, and let K = 255. If the resulting image is digitized with k bits of intensity resolution, and the eye can detect an abrupt change of eight shades of intensity between adjacent pixels, what value of k will cause visible false contouring?
