Abstract
A vision based sensor, image processing method and system, and an interactive device including the same are provided. The sensor includes an optical lens, an image acquisition chip that captures image resolution below a first threshold, and a micro-controller. The image acquisition chip acquires an object's image through the optical lens, and output an ultra-low resolution image with a resolution below the first threshold, and sends the ultra-low resolution image to the micro-controller. The micro-controller obtains object information by analyzing the ultra-low resolution image, and sends the object information to an external component, so that the external component performs a predefined act.
