A sensor driving device including a fixing part including a first sensor configured to output first inclination information and a plurality of magnets, a moving part which includes a plurality of coils disposed to face the plurality of magnets and a second sensor configured to output second inclination information and which is disposed to be spaced apart from the fixing part, an image sensor coupled to the moving part, and a support connecting the fixing part and the moving part and is made of an elastic material, a controller configured to control electrical signals provided to the plurality of coils using the first inclination information and the second inclination information.

Sensor driving device

An embodiment is a camera module comprising: a lens assembly comprising a liquid lens which comprises a first liquid and a second liquid forming an interface with each other; a temperature sensor for sensing the temperature information of the liquid lens; a controller for adjusting the interface by applying a driving signal to the liquid lens; and a compensation unit for outputting, to the controller, feedback information in which the inclination of the diopter of the liquid lens with respect to the driving signal is proportional to the temperature in a first area and the inclination of the diopter of the liquid lens with respect to the driving signal is inversely proportional to the temperature in a second area which differs from the first area.

Camera module

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.
