Abstract
An image sensor includes an optical system including a liquid lens, a nonvolatile memory that stores property information about an amount of change in a refractive power of the liquid lens in response to an application voltage, a temperature sensor that detects a temperature of the liquid lens, and a body module. The optical system, the nonvolatile memory, and the temperature sensor are disconnectable from the body module that includes a controller that performs image processing on image data received from a imaging device and performs liquid lens control for determining the application voltage to be applied to the liquid lens based on the property information stored in the nonvolatile memory, the temperature of the liquid lens detected by the temperature sensor, and a target value for the refractive power of the liquid lens and applying the application voltage to the liquid lens.
