Disclosed is an ambient light estimation system. The ambient light estimation system comprises: an image sensor that captures an image; a region of interest selector for determining at least one region of interest of the image; an occupancy detector that determines a presence state of an object in the region of interest; and an ambient light estimator which estimates the illuminance of the ambient light of the region of interest according to the brightness of the region of interest of the image.
一种环境光估算系统,包含影像传感器,撷取一影像;感兴趣区域选择器,决定影像的至少一感兴趣区域;占用检测器,决定感兴趣区域的对象的存在状态;及环境光估算器,根据影像的感兴趣区域的亮度以估算感兴趣区域的环境光的照度。
