Abstract
A projection system, including a projection target, a projection device, an image capturing device, and a processor circuit, is provided. The projection target includes a reflective surface and an anti-reflective film disposed on the reflective surface. The anti-reflective film defines a projection range. The image capturing device captures a first captured image containing the projection target. The first captured image includes an image of the anti-reflective film. The processor circuit determines a position and a shape of the anti-reflective film in the first captured image according to the first captured image. The projection device projects a projection image on the projection target. The projection device adjusts the projection image according to the position and the shape of the anti-reflective film, and correspondingly adjusts the projection image to the projection range. In addition, an image projection method is also provided.
