The invention provides projection device, a projection method and a projection system. The projection system includes the projection device. The projection method is for controlling the projection device. The projection device includes a projection apparatus, a video and audio processing circuit and a power control circuit. The video and audio processing circuit is coupled to the projection apparatus. The power control circuit is coupled to the projection apparatus and the video and audio processing circuit. The power control circuit is for receiving a power signal correspondingly provided by an external power supply unit when a switchable mechanism is in an open state. The power control circuit enables the projection apparatus and the video and audio processing circuit according to the power signal, such that the video and audio processing circuit outputs image data to the projection apparatus and controls the projection apparatus to project a dynamic projection image.
