Image processing apparatus and corresponding method for correcting optical distortions

摘要

In the DSP which processes an image pickup signal obtained via an optical lens (imaging optical system) and outputs the resulting image pickup signal as processes to an image display section, distortion aberration due to the optical lens is corrected according to a distance from a pixel position corresponding to an optical axis of the optical lens by changing the pixel position for each of a target image in radial directions when the pixel position corresponding to the optical axis is set as a center while suppressing an occurrence of jaggy in the resulting image. With this structure, an image pickup apparatus which corrects distortion aberration by changing pixel position only in radial directions from a pixel position corresponding to an optical axis of the imaging optical system while suppressing an occurrence of jaggy.
