Abstract
Light in a first emitting direction is irradiated on an observation target from a light projecting section and light from the observation target is received by an imaging section via an objective lens while a focal position of the light is changed in an optical axis direction of the objective lens, whereby a plurality of first original image data are generated in a plurality of focal positions. Light in a second emitting direction different from the first emitting direction is irradiated on the observation target from the light projecting section, whereby a plurality of second original image data are generated. First and second focused image data are respectively acquired on the basis of the pluralities of first and second original image data.
