Provided is an imaging method for correcting aberration generated when imaging an object to be inspected. The imaging method includes: irradiating an imaging area with a first light beam which is scanned by a scan unit and taking an image of the object to be inspected based on return light of the first light beam； detecting a moving amount of the object to be inspected； comparing the detected moving amount with a predetermined threshold value； and adjusting the imaging area to be irradiated with the first light beam. The adjusting includes determining in accordance with a result of the comparison to change the imaging area by at least one of: using the scan unit, and using an aberration correcting unit.
