Abstract

A microscope device includes an interface detector that detects the position of an interface present in a container containing an observation object and a controller that performs focus maintenance control for maintaining the focal position of an objective lens in a reference position distant from the interface detected by the interface detector in the direction of the optical path of the objective lens by a predetermined distance (an offset value) and, in a time period when an image capture unit is capturing images, changes the focal position from the reference position by moving at least one of the objective lens and observation object in the direction of the optical path with reference to the reference position.
