Then, the liquid lens (310) can be moved on a virtual grid pattern, and the point where the amount of light detected by the master sensor is the largest can be determined while applying voltages assigned to multiple codes to the liquid lens (310). Once the point where the amount of light is the largest is determined, the liquid lens (310) can be positioned at the point, and the epoxy that adheres the liquid lens (310) to the solid lens can be cured using ultraviolet rays. Thereafter, the liquid lens (310) can be fixed to the solid lens by curing the epoxy through heat.

Meanwhile, the lens unit formed by fixing the liquid lens (310) to the solid lens can be actively aligned with respect to the image sensor. While moving the lens unit on a virtual gridless surface and applying voltages assigned to multiple codes to the liquid lens (310), the point at which the amount of light detected by the image sensor is the largest can be determined and the lens unit can be fixed at the corresponding point. At this time, similar to the previous combination of the liquid lens (310) and the solid lens, the lens unit can be fixed in place through pre-curing and main curing using epoxy.

Furthermore, although it has been described above that the liquid lens (310) and the solid lens are first actively aligned and then the assembly of the liquid lens (310) and the solid lens is actively aligned with the image sensor, the solid lens and the image sensor may be actively aligned first and then the liquid lens (310) may be actively aligned, or the liquid lens (310) and the image sensor may be actively aligned first and then the solid lens may be actively aligned.
