Abstract: In order to effectively perform auto focusing and an OIS function, provided is an optical device in a first diopter state, the optical device comprising: a liquid lens having a variable diopter; a memory in which regions of interest (ROIs) according to the variable diopter are recorded; a lens control unit for retrieving a first ROI corresponding to the first diopter from the memory and configuring the first ROI; and a diopter operating unit for auto-focusing the first ROI to change the liquid lens to have a second diopter.

Abstract: Provided is an optical device for reducing the time for auto focusing (AF) performed by a contrast detection system, the optical device comprises a liquid lens having a curvature that varies on the basis of an applied electrical signal and the liquid lens may be auto-focused at one time from the current curvature (i.e., the first curvature state, p) to a target curvature corresponding to a distance to the subject (i.e., a second curvature state) based on the FV slope ratio.
