Title:
IMAGE SENSOR
Document Type and Number:
WIPO Patent Application WO/2020/189134
Kind Code:
A1
Abstract:
Provided is an image sensor, wherein an image of a subject is formed on an imaging surface of an imaging element by an optical system including a liquid lens. In the image sensor, the optical system is configured, together with a non-volatile memory in which characteristic information related to a change amount in refractive power of the liquid lens with respect to an applied voltage is stored and a temperature sensor for detecting the temperature of the liquid lens, so as to be separable from a main body module that is provided with a control unit that performs image processing for image data from the imaging element, and liquid lens control processing in which, from the characteristic information stored in the non-volatile memory, the temperature of the liquid lens detected by the temperature sensor, and a target value of the refractive power of the liquid lens, the applied voltage to be applied to the liquid lens is determined and the determined voltage is applied to the liquid lens.
