Abstract
An image processing apparatus includes: an image storage unit storing a first image affected by aberration of an optical system; a position information generation unit generating position information about a pixel of the first image corresponding to a scanned target pixel on the basis of position information about the target pixel scanned in the predetermined order and a distortion aberration table; an image output unit outputting a first image in which distortion aberration correction is performed in units of one pixel based on integer information about the position information generated by the position information generation unit; a first aberration correction unit, using fractional part information about the position information, correcting phase shift caused by distortion aberration for each pixel of the first image; and a second aberration correction unit generating the second image by correcting aberration other than distortion aberration in the first image.
