Abstract

According to an embodiment, a liquid lens control apparatus includes a liquid lens configured to control an interface between liquids in response to a driving voltage, a voltage booster configured to increase the level of a supply voltage and output a voltage having a higher level than the supply voltage, a controller configured to control the driving voltage, and a gyro sensor configured to sense the movement of the liquid lens and output a signal corresponding to the movement of the liquid lens. The controller acquires a signal corresponding to the movement of the liquid lens output from the gyro sensor during a period in which the voltage booster is in an OFF state, and controls the driving voltage using the signal corresponding to the movement of the liquid lens.
