WIPO Patent Application WO/2024/080234
Kind Code:
A1
Abstract:
This projection device projects an image onto a projection surface. The projection device comprises: a light source that emits light that is used for projecting an image; a lens on an optical path from the light source to a projection surface; an image capture element that is used for capturing an image of the projection surface; and an optical element that guides the light for projection from the light source to the lens, and guides light from the lens that is obtained by the capturing to the image capture element. A first partial optical path from the optical element to the projection surface of a first optical path from the light source to the projection surface and a second partial optical path from the projection surface to the optical element of a second optical path from the projection surface to the image capture element are aligned.
