Abstract

To enable an observation image according to an observation setting to be simply and quickly acquired while focusing on each of a plurality of observation positions. In batch replay, a plurality of observation positions are identified, and replay is executed for each of the plurality of observation positions. In particular, the plurality of observation positions to be observed in the batch replay are identified along with reception of a simple user operation such as designation of a target position (steps S207 and S209) or designation of an observation image (steps S203 and S208). Further, an observation setting when the observation image is acquired at each of the plurality of observation positions is designated along with reception of a simple user operation of designating a desired observation image from among observation images stored in a storage unit (step S203).

A magnification observation device comprising:

a placement table;
a lens configured to form an image of an observation object to be placed on the placement table;
an imaging sensor configured to capture the image of the observation object formed by the lens;
a first movement unit configured to change a relative horizontal position between the placement table and the lens in order to change an observation horizontal position;
a second movement unit configured to change a relative distance of the lens with respect to the placement table in order to change an observation height;
a measurement instrument configured to measure, as a focus height, an observation height of the lens with respect to the placement table in an in-focus state in which the observation object captured by the imaging sensor is focused;
an observation position registration section for registering the observation horizontal position;
an image acquisition unit configured to acquire an observation image of the observation object captured by the imaging sensor based on an observation setting;
a storage configured to store the observation image acquired by the image acquisition unit, the observation setting corresponding to the observation image, and the observation horizontal position corresponding to the observation image in association with each other;
an identifying unit configured to receive designation of a target position or designation of a target image from a plurality of the observation images stored in the storage, and configured to identify a plurality of observation horizontal positions based on the target position or an observation horizontal position stored in association with the target image;
an operation reception unit configured to receive a selection operation of selecting the observation image from among the observation images stored in the storage as replay targets;
a reading unit configured to read the observation setting associated with the observation image that received the selection operation by the operation reception unit;
and
a reproduction controller configured to determine whether to start batch replay to acquire an observation image sequentially at each of the plurality of observation horizontal positions based on the observation image selected as the replay targets, and in response to a start instruction for the batch replay, to successively control:
the first movement unit to relatively move a field of view of the imaging sensor to each a respective observation horizontal position of the plurality of observation horizontal positions identified by the identifying unit,
the second movement unit to adjust the relative distance at the respective observation horizontal position of the plurality of observation horizontal positions based on the focus height measured by the measurement instrument and shape information of the observation object, and
the image acquisition unit to acquire an observation image of the observation object, captured by the imaging sensor based on the observation setting read by the reading unit.
