Linearly proportional analysis between traditional grayscale method and super-grayscale method: (a) captured pattern with traditional grayscale method; (b) captured pattern with super-grayscale method; (c) linear relationship between input gray value and output gray value in traditional grayscale method; (d) linear relationship between output gray value and input gray value in the super-grayscale method.
