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.
