IMAGE PICKUP APPARATUS, IMAGE CORRECTION METHOD, AND MEDIUM STORING PROGRAM

An image pickup apparatus has a first/second optical system transmitting light through a first/second optical path, the second optical system having parallax with the first optical path; a switcher switching between the first and second optical paths in time series; an image sensor forming a first image and a second image by capturing subject images according to the light transmitted through the first optical path and the second optical path respectively; and a processor processing a signal output from the image sensor, wherein the processor calculates a motion vector in each divided region of a first base image from the first base image and a first reference image captured, interpolates an interpolation motion vector for each pixel of the first base image from the motion vector, and corrects the first base image or the first reference image to form a prediction image of the first image.
