Abstract
A camera module according to an embodiment includes base; a guide portion disposed on an inner side of the base; a lens assembly moving along the guide portion; and a substrate disposed on an outer side of the base, wherein the lens assembly includes a conductor disposed under a lower surface thereof, and wherein the substrate includes a resonance coil disposed in a region facing the lower surface of the lens assembly and overlapping at least a part of the conductor in a direction perpendicular to an optical axis direction in response to movement of the lens assembly.
Claims20
A camera module comprising:
- base;
- a guide portion disposed on an inner side of the base;
- a lens assembly moving along the guide portion;
- and
- a substrate disposed on an outer side of the base,
- wherein the lens assembly includes a conductor disposed under a lower surface thereof,
- wherein the substrate includes a resonance coil disposed in a region facing the lower surface of the lens assembly and overlapping at least a part of the conductor in a direction perpendicular to an optical axis direction in response to movement of the lens assembly, and
- wherein the resonant coil generates a magnetic field by resonating with a resonance frequency, and sensing a position of the lens assembly based on an inductance value that changes according to a change in a strength of the generated magnetic field.
