Dynamic vision sensor is a novel type of imaging sensor. "Regular" image sensors output a 2D image where each pixel encodes light intensity. Dynamic vision sensor outputs pixel-level changes in the scene. For dynamic applications you usually are only concerned about the changes in image (e.g. object tracking, robotic navigation). An image sensor which only outputs changes reduces image processing requirements considerably! Example: 640x480 greyscale image at 120FPS is about 35MiB/s of data. If the scene is static, all the computation cycles are wasted just to find out there is nothing new in a frame. That is rather heavy load for tablet/cellphone class processors which are usually found in embedded devices!
