摘要： An optical element includes a prism and a light blocking member. The prism has a first surface, a second surface and a third surface. The first surface is connected to the second surface. The third surface is connected between the first and second surfaces and opposite to a light valve of a projection device. The first surface reflects an image light beam from the light valve to allow the image light beam to pass through the second surface. The light blocking member is disposed on the prism and includes a first light blocking portion and a second light blocking portion adjacent to each other. The first light blocking portion shields a part of the first surface adjacent to the second surface, and the second light blocking portion shields a part of the second surface adjacent to the first surface. A projection device using the optical element is also provided.

摘要： A feature surface projection system includes a projector, a camera, and a controller. The projector projects a structured light and an image beam to a feature surface at different times. The structured light forms a structured light pattern on the feature surface, and the image beam forms an image on the feature surface. The camera photographs the structured light pattern and the image at different times. The controller is electrically connected to the projector and the camera, calculates a position of a feature point of the feature surface, and determines a difference between a position of a feature point of the image and the position of the feature point of the feature surface to determine whether to adjust the image beam. A projection method for a feature surface is also provided. The feature surface projection system provides an automatic alignment function between a projected content and the feature surface.

摘要： A projection apparatus, including an illumination system, a light valve, a first movable reflector, a first projection lens, a second projection lens, and a driving module, is provided. The illumination system is configured to provide an illumination light beam. The driving module is connected to the first movable reflector and is configured to drive the first movable reflector to move. The projection apparatus has a first projection mode and a second projection mode for being performed. In the first projection mode, the driving module controls the first movable reflector to move to a first position. In the second projection mode, the driving module controls the first movable reflector to move to a second position, and the first movable reflector is not located on a transmission path of an image light beam.
