Abstract

An image signal evaluator calculates a first image signal evaluation value based on an image signal captured in a state where a focusing position is adjusted to an imaging target. A water droplet adhesion determiner determines whether there is a possibility that a water droplet may be adhered onto an imaging window by comparing a first image signal evaluation value and a threshold value. In a case where it is determined that there is the possibility, an image signal evaluator calculates a second image signal evaluation value based on an image signal captured in a state where the focusing position is adjusted to a position of a close distance. The water droplet adhesion determiner determines whether a water droplet is adhered onto the imaging window by comparing the first image signal evaluation value and the second image signal evaluation value.
