Abstract

An active monitoring system with multi-spot image display and a method thereof are disclosed. The active monitoring system includes at least one image-obtaining module, at least one image-receiving module, and at least one image-display module. The image-obtaining modules respectively obtain a dynamic image and generate a triggering signal according to the obtained dynamic image. The image-receiving modules are connected with the image-obtaining modules via a network. Each of the image-receiving modules is controlled by the triggering signal to receive and process the dynamic image. The image-display modules are respectively connected with the image-receiving modules and are controlled by the triggering signal to display the processed dynamic image.

Claims
