Sketch the image in Problem 2.7 for k = 2.

2.7 Suppose that a flat area with center at (x0, y0) is illuminated by a light source with intensity distribution

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?
