Abstract
A method of shoot suppression when transition properties of an image signal are improved. The method includes improving transition properties of an original image signal and filtering a local overshoot and/or undershoot at edges of the transient-improved image signal. Accordingly, a transition time of the original image signal may be reduced and generation of shoots may be suppressed so that a quality-improved image is generated.
