Abstract
A projection device including at least one projection module and at least one adjusting structure is provided. The projection module has at least one optical axis. The projection module is adapted to provide an image beam. The image beam is transmitted along a light transmission path to a projection target and forms a projection image. The adjusting structure is connected to the projection module. The adjusting structure is adapted to drive at least a part of the projection module to rotate along the optical axis such that the projection image rotates.
Claims21
A projection device, comprising at least one projection module and at least one adjusting structure,
- the at least one projection module having at least one optical axis, the at least one projection module being adapted to provide an image beam, wherein the image beam is transmitted along a light transmission path to a projection target and forms a projection image;
- the at least one adjusting structure being connected to the projection module, wherein the adjusting structure is adapted to drive at least a part of the projection module to rotate along the optical axis such that the projection image rotates.
A projection method, applied to a projection device, wherein the projection device has at least one projection module and at least one adjusting structure, wherein the at least one projection module has at least one optical axis, the projection method comprising:
- providing an image beam transmitted along a light transmission path to a projection target and forming a projection image;
- and
- driving at least a part of the projection module to rotate along the optical axis by the at least one adjusting structure such that the projection image rotates.
