More Information
Summary:Provided are a degradation compensating device which can accurately detect a logo region even in a video image as well as a still image by detecting the logo region using 3D depth map information, and can prevent logo colors from being distorted by converting a logo in the detected logo region into a transparent logo with low luminance, and a display device including the same. The degradation compensating device includes a depth map extracting unit, a logo region detecting unit, a color analyzing unit, and a gray scale level adjusting unit. 3D 깊이 맵 정보를 이용하여 로고영역을 검출함으로써 정지영상 및 동영상에서도 정확하게 로고영역을 검출할 수 있고, 검출된 로고영역의 로고를 저휘도의 반투명 로고로 변환함으로써 로고 색상이 왜곡되는 것을 방지할 수 있는 열화보상장치 및 이를 포함하는 표시장치가 제공된다. 열화보상장치는 깊이 맵 추출부, 로고영역 검출부, 컬러분석부 및 계조레벨 조절부를 포함한다.
