Abstract
Vertical lines in a distorted image, which are curved by distortion, are converted to straight vertical lines in a first image period. In a subsequent image period horizontal lines in the distorted image, which are curved by the distortion, are converted into straight lines. As the correction is effected in stages, it can be performed in a relatively fast manner, and a corrected image is available after one image period.
