IMAGE PROCESSING METHOD AND IMAGE PROCESSING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an image processing method or the like which can correct image distortion and deformation without relying on the content of an obtained image.

SOLUTION: An image processing method includes the steps of: estimating corners of a contour of an object area in an obtained image; searching for contour lines of the object area between every two points which are offset from the estimated corners within a predetermined angle range along a direction moving away from the object area respectively, and determining intersection points of the contour lines as final corners of the contour of the object area; and determining contour lines between the final corners as a final contour of the object area.
