Abstract
An embodiment provides an optical device comprising: a lens assembly which includes a liquid lens comprising a first liquid and a second liquid forming an interface therebetween; a temperature sensor which senses the temperature of the liquid lens; and a controller which controls a driving signal for the liquid lens, wherein the controller controls the driving signal by using a first function when the sensed temperature is in a first temperature range and by using a second function different from the first function when the sensed temperature is in a second temperature range.
