Abstract
An image processing apparatus comprises a selection unit for selecting at least one pair of two layer image data items having focus positions shifted oppositely, by equal distances, in a positive direction and a negative direction relative to a reference depth in a specimen from among a plurality of layer image data items acquired with the focus positions set at different depths in the specimen and a phase contrast correction unit for performing, for each of the pair of the two layer image data items selected by the selection unit, a correction process which reduces a difference in phase contrast component between the two layer image data items.
