<p>PROBLEM TO BE SOLVED: To provide an imaging device, an image correction device, software, and an image correction method, capable of correcting reduction in quantity of light of a lens with accuracy.SOLUTION: An inclination of a solid line is rapidly changed at an image height point 4. On the other hand, at an image height point in a broken line corresponding to the image height point 4, the change is not so rapid compared with the solid line. Therefore, from the image height point 4 to the image height point 7, the broken line largely deviates from the solid line. A photographed image is corrected on the basis of an inclination An of the solid line. Therefore, if the photographed image is corrected on the basis of the solid line deviated from the broken line, probability that correction unevenness (a correction trace) appears in the vicinity of the image height point 4 between an inclination A4 and an inclination A5 where a change in inclination is large is high. Thus, an image height point with large inclination change described as follows, that is an inflection point, is detected to adjust the change in inclination.</p> |
