Abstract
A magnified observation apparatus includes an FOV changer, an in-focus degree evaluator, and a focus sequence executor. The in-focus degree evaluator calculates in-focus degree feature quantities, which represent in-focus degrees of image data corresponding to images to be displayed by a display controller on a display. The focus sequence executor executes an FOV-moving focus sequence in which a focusing device adjusts a relative distance between a focus position of the objective lens and an observation object in accordance with in-focus degree feature quantities of image data that are successively calculated by the in-focus degree evaluator corresponding to images of the observation object that are captured during movement of an observation FOV by the FOV changer so that a live image of the observation object is displayed on the display based on image data that is obtained during the movement of an observation FOV by the display controller.
