A vehicle collision event announcing system is provided. The system includes: a processor; an image capturing unit, coupled to the processor, for capturing vehicle images from at least a part of the vehicle; a collision sensing unit, for detecting whether the vehicle is running into a probable collision event; and a feature image comparison unit, coupled to the processor, for when the collision sensing unit detects the probable collision event, comparing the vehicle images before and after the probable collision event to determine whether the probable collision event is a real collision event which causes damage to the vehicle and/or the seriousness of the damage of the real collision event.
