    摘要： A variable lens includes a first substrate that is light transmissive, a first liquid, a movable film that is in contact with the first liquid and is light transmissive and elastically deformable, a second liquid that is in contact with the movable film, and a second substrate that is light transmissive, the components described above sequentially arranged in the direction in which the beam passes along the optical axis. The first and second liquids differ from each other in terms of refractive index. In the variable lens, the pressures of the first and second liquids are adjusted to cause the movable film to curve in the direction along the optical axis. At least one of the first and second substrates has power as a lens.

    摘要： An actuator including a first circuit board on which an image sensor is disposed, a first housing disposed on the first circuit board, a lens assembly disposed within the first housing, and a second circuit board disposed on the first side portion of the first housing where a gyro sensor is disposed, and a third circuit board driving the lens assembly is provided. The third circuit board may include a first region disposed on the first side portion of the first housing and in which a first coil driving the lens assembly is disposed. The first coil may overlap the second circuit board in a direction perpendicular to an optical axis direction.
