Abstract
Disclosed is a method for correcting a facial region detected from image data for photoprinting of improved image quality. The method includes an image data input step of inputting the image data to an image processing device; facial region detection step of extracting a skin color region from the inputted image data and detecting a planar face or a rotated planar face from a face-existing candidate region; a region division step of dividing the facial region detected in the facial region detection step; a correction step of extracting a distortion data value from the region divided in the region division step and conducting correction; and a photoprinting step of visually outputting the image data finally corrected in the correction step. Various types of distortion of the facial image is effectively corrected before it is printed by a photoprinter so that the image quality is improved.
