<P>PROBLEM TO BE SOLVED: To correct the chromatic aberration of magnification corresponding even to an aberration generation pattern whose point symmetry is lost, by as little data and calculation amount as possible. <P>SOLUTION: A displacement amount calculation part 610 selects uniform aberration correction data 621 from a uniform aberration correction table 620 on the basis of lens control information, and calculates an aberration correction displacement amount SFT2. A lens control part 140 displaces a vibration-proof lens group 132 on the basis of the aberration correction displacement amount SFT2 and corrects uniform aberration. A concentric circular aberration correction amount calculation part 213 selects concentric circular aberration correction data 241 from a concentric circular aberration correction table 240 on the basis of the lens control information, a processing object color, and an image height; and calculates a concentric circular aberration correction amount. A color shift destination pixel value calculation part 214 and a pixel value correction part 215 calculate a pixel value of a color shift destination pixel corresponding to a processing object pixel on the basis of the concentric circular aberration correction amount and rewrite the pixel value of the processing object pixel with the calculated pixel value. <P>COPYRIGHT: (C)2012,JPO&INPIT |
