Magnification chromatic aberration correction device, magnification chromatic aberration correction method and magnification chromatic aberration correction program

摘要

PROBLEM TO BE SOLVED: To provide a chromatic difference of magnification correcting device capable of eliminating video blurring resulting from chromatic difference of magnification even when a lens parameter is changed to a variety of values to perform photographing.;SOLUTION: This chromatic difference of magnification correcting device 1 comprises a signal inputting means 2 for inputting a primary color signal, a lens parameter inputting means 3 for inputting a photographic lens parameter of a camera that has performed photographing, a correction data storing means 4 for prestoring a plurality of pieces of correction data showing the amount of color slurring in a prescribed lens parameter, a correction data selecting means 5 for selecting correction data of lens parameters sandwiching the photographic lens parameter from the correction data, a correction amount calculating means 6 for performing interpolation and calculating a correction amount on the basis of the selected correction data, an aberration correcting means 7 for correcting a pixel value of the primary color signal on the basis of the correction amount, and a signal outputting means 8 for outputting the primary color signal with the corrected pixel value.;COPYRIGHT: (C)2006,JPO&NCIPI
