  • Patent number: 10422986
    Abstract: An emitting section of a light projecting section is provided to surround an optical axis of an objective lens of a lens unit. The optical axis of the emitting section is substantially the same as the optical axis of the objective lens. Ring illumination is irradiated on the observation target from the emitting section and light from the observation target is received by an imaging section via the objective lens, whereby first original image data is generated. Directional illumination is irradiated on the observation target from the emitting section and the light from the observation target is received by the imaging section via the objective lens, whereby second original image data is generated. Image data for display indicating an image of the observation target that should be obtained when it is assumed that light in a specific emitting direction is irradiated on the observation target is generated.

  • Patent number: 8994810
    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 xt-axis and a yt-axis. In this case, moving amounts along the xt-axis and the yt-axis are controlled based on a rotational angle detected by a rotational angle detecting part.
