Magnifying observation apparatus

A magnifying observation apparatus that provides an image of the observation target corresponding to an observation region, the magnifying observation apparatus comprising:

• a motorized table for placing the observation target;
• an illumination which illuminates the observation target on the motorized table;
• an observation optical system including an objective lens and a motorized magnification changer;
• a magnifying controller which controls the motorized magnification changer to change a magnification of the observation optical system;
• a table controller which change a horizontal position of the motorized table;
• an imaging element which acquires an image of the observation target corresponding to an observation region via the observation optical system;
• a navigation-image generator which generates a navigation image from a first plurality of images of the observation target illuminated by the illumination, the first plurality of images acquired under first imaging condition by the imaging element;
• an imaging-condition storing section configured to store the first imaging conditions;
• a display which displays the navigation image;
• and
• an observation-image acquiring section configured to determine a first observation region on the basis of designation of a position on the navigation image, control the table controller and/or the magnifying controller according to the first observation region, and acquire an observation image of the observation target corresponding to the first observation region with the imaging element, wherein
• the navigation-image acquiring section controls, in response to designation associated with adding a region of the navigation image, the table controller according to the region to be added and, when a current imaging condition is different from the first imaging condition stored in the imaging-condition storing unit, changes the current imaging condition to the first imaging condition, update the navigation image by adding an image corresponding to the region to be added acquired under the first imaging condition by the imaging element.
