IMAGE PROCESSING APPARATUS FOR OFFERING A SMOOTH IMAGE AND A METHOD FOR IMPROVING SHARPNESS

摘要

PURPOSE: An image processing apparatus and a method thereof are provided to improve sharpness by applying optimal algorithm to each edge area.;CONSTITUTION: An image processing method comprises steps of receiving image signal from an external device(S601); filtering brightness component from the input image signal(S603); detecting edge signal from the filtered brightness component(S604); and increasing sharpness of edge signal area by discriminating the detected edge signal(S609).;COPYRIGHT KIPO 2011
