Abstract

Lights in a plurality of emitting directions different from one another are selectively irradiated on the observation target from a light projecting section. A plurality of image data indicating images of the observation target at the time when the lights in the plurality of emitting directions are respectively irradiated on the observation target are generated by an imaging section. An imaginary emitting direction of light is designated on the basis of operation of an operation section by the user. Image data for display indicating an image of the observation target that should be obtained when it is assumed that the light in the designated emitting direction is irradiated on the observation target is generated on the basis of the designated emitting direction and the plurality of image data generated by the imaging section. The image based on the generated image data for display is displayed on the display section.

Dependent claims

A magnifying observation apparatus comprising:

a stage on which an observation target is placed;
a light projecting device configured to selectively irradiate lights in a plurality of emitting directions different from one another on the observation target placed on the stage;
an imaging section configured to receive light from the observation target and respectively generate a plurality of image data indicating images of the observation target at times when the lights in the plurality of emitting directions are respectively irradiated on the observation target;
a designating section configured to designate an imaginary emitting direction of light on the basis of operation by a user;
a data generating section configured to generate, on the basis of the emitting direction designated by the designating section and the plurality of image data generated by the imaging section, image data for display indicating an image of the observation target that should be obtained when it is assumed that the light in the designated emitting direction is irradiated on the observation target;
and
a display section configured to display an image for display based on the image data for display generated by the data generating section.
