Abstract: A microscope system comprises a microscope body, an image sensor mounted on the microscope body, and a stage that moves in an X-axis direction and a Y-axis direction, and places a slide as an observation object. The stage includes a mark used to indicate a stage reference position. The microscope system obtains positions of the stage in the X-axis direction and the Y-axis direction, and detects the stage reference position indicated by a mark provided on the stage and a slide reference position indicated by a mark provided on a slide placed on the stage. The microscope system manages the position of the stage by coordinates based on the slide reference position if the slide reference position is detected, and manages the position of the stage by coordinates based on the stage reference position if the slide reference position is not detected.

Abstract: A microscope system comprises a microscope body, an image sensor mounted on the microscope body via mounting means and configured to capture an observation image under a microscope, and a stage that moves in an X-axis direction and a Y-axis direction, which are orthogonal to each other, and places a slide as an observation object and includes a mark used to indicate a stage reference position. The microscope system obtains positions of the stage in the X-axis direction and the Y-axis direction, and detects, from an image captured by the image sensor, the stage reference position indicated by a mark provided on the stage and a slide reference position indicated by a mark provided on a slide placed on the stage. The microscope system manages the position of the stage by coordinates based on the slide reference position if the slide reference position is detected, and manages the position of the stage by coordinates based on the stage reference position if the slide reference position is not detected.
