IMAGE PROCESSING DEVICE AND METHOD CAPABLE OF REDUCING A HUNTING PHENOMENON BY APPLYING A WEIGHTED VALUE

摘要

PURPOSE: Image processing device and method are provided to reflect a property of an initial image on contrast ratio improvement, thereby implementing optimized brightness and reinforcement of a contrast ratio.;CONSTITUTION: A brightness improvement unit(110) improves brightness of an inputted image based on a predetermined knee-point by increasing the brightness of a dark image and decreasing the brightness of a light image. A contrast ratio improvement unit(120) improves a contrast ratio of the image outputted from the brightness improvement unit.;COPYRIGHT KIPO 2013;[Reference numerals] (110) Brightness improvement unit; (120) Contrast ratio improvement unit; (AA) Image input; (BB) Image output;
