MICROSCOPE DEVICE AND PROGRAM

Provided are a microscope apparatus capable of executing auto-focus control that appropriately follows a high-speed scan in a case of capturing a high-magnification and wide view image of an observation target contained in a container having large variations in the bottom surface, and a program. In a case where a microscope apparatus main body 10 scans the bottom surface of the cultivation container 50 by synchronously controlling a piezoelectric element 15A and an actuator 15B serving as optical axis-directional transport devices having different properties from each other, an objective lens 14b of the imaging optical system 14 is transported to a focus position in the optical axis direction.
