MOTION DETECTION DEVICE AND DETECTING METHOD THEREOF

原文（中文）

There is provided a motion detection device including a pixel array, multiple comparators and multiple logic check circuits. One comparator is coupled to a pair of pixel columns of the pixel array. The pixel array acquires a reference image and a current image. The comparators generate a reference feature position map corresponding to the first image and generate a current feature position map corresponding to the current image. The multiple logic check circuits process the reference feature position map and the current feature position map to detect a motion.
