The present invention relates to a system for a dynamic brightness change of a display device for a vehicle. The present invention comprises: a camera brightness estimation unit detecting brightness at a driver's gaze from a camera installed to have the same gaze with a driver; an image brightness estimation unit dividing an image captured by a front camera into a plurality of patches, adding weighted values to a patch average value according to a distance after calculating the average value of each divided patch, and estimating the brightness of the image by calculating a median value of the entire patch; and a dynamic brightness conversion unit converting external light density into the target brightness of the image by using a pre-stored lookup table for dynamically changing the brightness to be matched to the light density in a direction of the driver's gaze.
본 발명은 차량용 디스플레이 장치의 동적 밝기 변화 시스템에 관한 것이다. 본 발명은 운전자와 동일한 시선을 갖도록 설치된 카메라로부터 운전자 시선에서의 밝기를 검출하는 카메라 밝기 추정부; 전방 카메라에 의해 촬영된 영상을 복수의 패치로 분할하고, 분할된 각 패치별 평균값을 계산한 후 패치 평균값에 거리에 따른 가중치를 추가하고, 전체 패치의 중앙값을 계산하여 영상 밝기를 추정하는 영상 밝기 추정부; 및 운전자 시선 방향의 광 밀도에 맞도록 동적으로 밝기를 변화시키기 위하여, 기 저장된 룩업 테이블을 이용하여 외부 광 밀도를 목표 영상 밝기로 변환하는 동적 밝기 변환부를 포함한다.
