Figure 1 to 4 represent conditions where the lens is focused (1) too near, (2) correctly, (3) too far and (4) way too far. It can be seen from the graphs that the phase difference between the two profiles can be used to determine not just in which direction, but how much to change the focus to achieve optimal focus. Note that in reality, the lens moves instead of the sensor.
