PURPOSE: A camera module error correction method capable of accurately determining automatic focusing about a subject is provided to reduce the difference between a design value and a measurement value. CONSTITUTION: A camera module error correction method capable of accurately determining automatic focusing about a subject is as follows. A measurement tracking curve is calculated by moving the location of a zoom lens(S10). The wide correcting tracking curve is calculated by comparing a design tracking curve and a measurement tracking curve(S20). The correction tracking curve is matched with the selected point-to-point. By using the calculated error ratio, the design value tracking curve is revised(S40).
