Abstract
An image sensor includes an imaging device, an optical system including a liquid lens, a temperature sensor that detects a temperature of the liquid lens, a heater that heats the liquid lens, a temperature adjuster that controls the heater to adjust the temperature of the liquid lens to a predetermined temperature, a nonvolatile memory storing property information about the liquid lens, a refractive power controller that determines, based on a target refractive power and the property information stored in the nonvolatile memory, an application voltage applicable to the liquid lens adjusted to have the predetermined temperature and applies the application voltage to the liquid lens to control a refractive power of the liquid lens to match the target refractive power, and an image processor. The optical system, the nonvolatile memory, and the temperature sensor are disconnectable from a body module including the refractive power controller and the image processor.
