Claim Text:
1. An imaging method for taking an image of an object to be inspected from reflected light obtained by irradiating the object to be inspected with measuring light, in which an aberration generated in the object to be inspected, when the image is taken, is corrected by an aberration correction unit, the imaging method comprising the repeatedly performed steps of: measuring an amount of the aberration generated in the object to be inspected; comparing (a) a prior aberration amount, measured by measuring an amount of the aberration, with (b) a subsequent aberration amount that is subsequent in time sequence; storing, in a storage unit, (a) a control state of the aberration correction unit at a time of measuring the amount of the aberration, in association with (b) a corresponding amount of the aberration; and correcting the aberration by controlling the aberration correction unit in accordance with the measured amount of the aberration, wherein the storing is performed when the subsequent aberration amount is equal to or smaller than the prior aberration amount, and wherein the aberration corresponding to the subsequent aberration amount is corrected by the aberration correction unit in the control state stored in the storage unit when the subsequent aberration amount is larger than the prior aberration amount.
