polynomial. The coefficients thus obtained were used in the procedure
removing the photograph radial distortion deformation.
One should note that in the zoom lenses distortion coefficients vary
along with the focal length, they should be determined for several focal
lengths separately.
All the photographs included in this paper were taken by the author with
Minolta Konica Dimage A2 digital camera with the focal length 28 mm.
