    Patent number: 10520709
    Abstract: A projection system includes a long-focus lens that is able to generate an image independently with a focal length between 70-300 mm, a short-focus lens that is able to generate an image independently with a focal length between 3-8 mm and shares an optical axis with the long-focus lens and at least one reflector to reflect the optical axis for direction change. When the long-focus lens generates an image, the short-focus lens then generates the image to a pre-determined position thereby.
