A magnified observation apparatus includes an illuminator, a feature quantity calculator, and an illumination controller. The illumination controller selectively performs first and second sequences. In the first sequence, the illuminator is operated in the first lighting pattern, and a display is operated to display a live image of the observation object that is irradiated with the first lighting pattern by a display controller. In the second sequence, the illuminator is operated in the second lighting pattern as at least one of the different illumination directions that is selected based on the feature quantities of the image data, which are calculated correspondingly to the different illumination directions by the feature quantity calculator, and the display is operated to display by the display controller an image of the observation object that is captured when the observation object is irradiated with the second lighting pattern.

Magnified observation apparatus, magnified observation method, and non-transitory computer-readable storage medium or storage device

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.

Magnified observation apparatus

To make it possible to observe an observation target from a plurality of different angles and to make, when acquiring and displaying an image including a placement unit separately from an observation image, the image an image with less discomfort. A side-view image capturing unit having an optical axis different from an optical axis of a magnified observation image capturing unit is provided facing a placement table. The side-view image capturing unit is provided so as to eliminate a connection or to lower a connection with a swinging motion of a supporting member to acquire a side-view image. A magnified observation image and the side-view image are displayed.

Magnifying observation apparatus

To easily obtain a magnified observation image in which a user's intention is reflected. A side-view image acquired by a side-view image capturing unit is displayed on a display unit. An arbitrary position designation by a user is received on the side-view image displayed on the display unit. A magnifying observation apparatus is controlled based on the received position.

The present invention is for saving the time of searching a visual field to be observed and observing a synthetic image. A magnifying observation apparatus includes a controller configured to set an imaging condition, to generate a first image to be displayed in a first display mode by performing a first image processing on the image acquired on the imaging condition, to generate a second image to be displayed in a second display mode by performing a second image processing on the image, to detect an image changing operation including at least one of changing of the imaging condition and changing of a visual field, and to switch from the first display mode to the second display mode in response to detect the image changing operation.

Magnifying observation apparatus, magnified image observing method and computer-readable recording medium

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-axis and a y-axis. In this case, moving amounts along the x-axis and the y-axis are controlled based on a rotational angle detected by a rotational angle detecting part.
