Abstract
An image sensor includes an imaging device, an optical system including a liquid lens to form an image of a subject on an imaging surface of the imaging device, and a controller that performs a refractive power control process of adjusting an application voltage applicable to the liquid lens to control a refractive power of the liquid lens, and a recognition process of analyzing image data from the imaging device to recognize predetermined information about the subject. The controller is operable in a plurality of operation modes each with a different wait period from a change in the application voltage to the liquid lens in response to the refractive power control process to a start of the recognition process.
