(57) [Summary] In drive control of an optical element utilizing electrocapillary phenomenon, drive control according to temperature can be performed, and the effect of hysteresis can be ignored or the effect of hysteresis can be ignored. To provide an optical device that can easily correct the following. An optical device having an optical element whose optical characteristics change due to a change in an interface shape due to application of a voltage, wherein a first voltage for applying a predetermined voltage is set to an environmental temperature of the optical element. To apply as an adapted voltage, A means for generating a transient second applied voltage before generating the first applied voltage can be configured to perform drive control in accordance with temperature, and can ignore the influence of hysteresis. Or the effect of hysteresis can be easily corrected. |
