Patent number: 8750641Abstract: Provided are an apparatus and method for correcting distortion of an image. The method includes finding center point vectors including lens distortion center information about an image and dividing the image into at least two blocks on the basis of the center point vectors, and determining representative directions of the at least two divided blocks and removing outlier vectors not indicating the representative directions from the blocks to estimate a lens distortion center. Accordingly, accurate image correction is enabled by estimating distortion centers of images generated by devices equipped with any lens. Also, image content improving lens distortion correction performance is differentiated from image content degrading the same by picking out image content improving lens distortion center estimation performance, so that a superior image correction effect to other image correction techniques can be obtained.Type: GrantFiled: September 29, 2011Date of Patent: June 10, 2014Assignee: Postech Academy—Industry FoundationInventors: Moon Kyu Song, Hyun Woong Cho, Byoung Kwang Kim, Woo Jin Song
