Beschreibung
Zusammenfassung:	An image processing device includes a current limiting unit which calculates correction data to reduce a driving current of an image signal based on an on pixel rate of the image signal and calculates correction brightness data of the image signal based on the correction data, and a brightness control unit which selects a dimming value and a gamma set based on correction brightness data. Accordingly, the present invention can prevent a loss of the image signal in an automatic current limiting driving process. 영상 처리 장치는 영상 신호의 온 픽셀율에 기초하여 영상 신호의 구동 전류를 감소시키는 보정 데이터를 연산하고, 보정 데이터에 기초하여 영상 신호의 보정 휘도 데이터를 연산하는 전류 제한부 및 보정 휘도 데이터에 기초하여 감마 세트 및 디밍 값을 선택하는 휘도 제어부를 포함한다.
