Title: OBSERVATION DEVICE AND METHOD, AND OBSERVATION DEVICE CONTROL PROGRAM
Abstract:
An observation device and method for moving a stage in relation to an image-forming optical system and observing an image of an observation object, and an observation device control program, wherein the effect of positional fluctuation in the vertical direction that accompanies movement of the stage is reduced, and autofocus control is performed with high precision. Before an observation region of an image-forming optical system 14 reaches an observation position in a culture container 50, the position of the culture container 50 in the vertical direction in the observation position is detected in advance by a displacement sensor for autofocusing, and when an objective lens is to be moved in an optical axis direction on the basis of the detected position, the error between the position detected in advance of the stage 51 in the vertical direction in the observation position and the position of the stage 51 in the vertical direction at the time the observation region of the image-forming optical system 14 is scanned to the observation position is acquired, and the objective lens is moved in the optical axis direction on the basis of the error.
