Title:
IMAGE SENSOR
Document Type and Number:
WIPO Patent Application WO/2021/014843
Kind Code:
A1
Abstract:
This image sensor comprises: an imaging element; an optical system including a liquid lens; a temperature sensor for detecting the temperature of the liquid lens; a heating unit for heating the liquid lens; a temperature regulation unit which regulates the temperature of the liquid lens to a predetermined temperature by controlling the heating unit; a non-volatile memory in which characteristic information on the liquid lens is stored; a refractive power control unit which determines, on the basis of a target refractive power and the characteristic information stored in the non-volatile memory, an application voltage to be applied to the liquid lens the temperature of which is adjusted to the predetermined temperature, and applies the application voltage to the liquid lens to control the refractive power of the liquid lens to the target refractive power; and an image processing unit, wherein the optical system, the non-volatile memory, and the temperature sensor are configured to be separable from a main body module including the refractive power control unit and the image processing unit.
