Abstract: A projection device with automatic spot correction includes an image generation unit, a light sensor, and a controller. The image generation unit outputs a light beam to scan to generate an image. The light sensor senses the light beam to obtain a spot position formed on the light sensor. The controller is coupled to the image generation unit and the light sensor. When executing an automatic spot correction procedure, the controller calculates an offset value of the spot position and uses an adjustment mechanism to correct the spot position.
