Abstract: There is provided a calibration apparatus for a camera module capable of calibrating the difference in optical characteristics between left and right images of a binocular camera module in real time by capturing images of a plurality of rotating test boards. The calibration apparatus of a camera module includes: a test unit including two or more mutually connected test boards, the test boards having images captured by a camera module and rotating at a pre-set angle; and a calibration unit receiving the images of the test boards captured by the camera module and calibrating optical characteristics thereof.
