Abstract:
1. A method for forming and picking up an image by using an apparatus having a frontal plane with an opening, an intermediate plane, and a two-dimensional image pick-up device, the method comprising the steps of: forming a first undistorted image of an object by waves of a first kind through the opening of the frontal plane onto a front surface of the intermediate plane; converting the waves of the first kind that formed the first undistorted image of the object to waves of a second kind emitting from the rear surface of the intermediate plane, the intermediate plane acting as a wave converter from the waves of the first kind to the waves of the second kind, the waves of the second kind detectable by the two-dimensional image pick-up device; forming a second distorted image by waves of the second kind onto an image sensor of the two-dimensional image pick-up device; and outputting a corrected image of the object by the two-dimensional image pick-up device, by using information of the first undistorted image and second distorted image for distortion calibration.
