Abstract

Provided is a magnification observation device capable of easily moving an observation object in a desired direction even when a stage is rotated, and capable of preventing a desired region of the observation object from going outside an imaging region due to rotation of the stage. The observation object is placed on the placement surface of the stage. The observation object is imaged by an imaging unit, to acquire image data of the imaging region. Based on the image data acquired by the imaging unit, an image of the observation object is displayed by the display part as an observed image. The stage is moved relatively with respect to the imaging unit along an x t -axis and a y t -axis. In this case, moving amounts along the x t -axis and the y t -axis are controlled based on a rotational angle detected by a rotational angle detecting part.

First claim

What is claimed is:

1. A magnification observation device, comprising:
an imaging part that images an observation object, to acquire imaging data of an imaging region;
a display part that displays an image of the observation object as an observed image based on the image data acquired by the imaging part;
a stage that has a placement surface on which the observation object is placed, and is provided relatively rotatably with respect to the imaging part around a rotational axis…
