PURPOSE: A method of correcting an interval between lenses is provided to automatically correct an interval between a second lens and a first lens by calculating the interval between the first and the second lens. CONSTITUTION: In a method of correcting an interval between lenses, a first lens of a camera faces an alignment mark formed on an object(S110). The optical axis of the first lens and center of the alignment mark are on the same line(S120). A second lens of a camera faces an alignment mark formed on an object(S130). The second interval between the optic axis and the alignment mark is calculated(S140). The first interval is corrected by using the first and the second interval (S150).
