LIQUID LENS CONTROL DEVICE

Abstract:

A liquid lens control apparatus according to an embodiment includes: a liquid lens containing a first liquid and a second liquid that form an interface with a first electrode and a second electrode; a lens driver applying a voltage to the first electrode and the second electrode to control the interface, and including a plurality of switching elements; a temperature sensing unit sensing a temperature of the liquid lens; and a control unit controlling the lens driver so that the interface forms a target interface, wherein the control unit controls switching states of the plurality of switching elements of the lens driver to be maintained during a temperature sensing period in which the temperature sensing unit operates.
