Abstract
A projection device and a projection method thereof are provided. The projection device includes an optical engine, a ranging unit, and a processor. The optical engine projects an image beam to a target area to form a first image. The ranging unit emits testing light beams, detects reflected light beams reflected from the testing light beams, and obtains effective sensing information from the reflected light beams. The processor is coupled to the ranging unit and the optical engine, receives the effective sensing information from the ranging unit, and generates first projection distance information according to the effective sensing information. The processor controls the optical engine so that the first image corresponding to the image beam is located within an effective focal length range of the projection device.
