| 发明名称 | Projector, image projecting system, and image projecting method | ||
| 摘要 | A projector system may include a camera, a controller unit and a projecting unit. The camera may pick up a first image of a projection surface by visible light and a second image of the projection surface by a decreased visible light. The controller unit may perform a keystone distortion correction processing on a basis of the first image and perform an interactive processing on a basis of the second image. The projecting unit may project an image based on the performed keystone distortion correction. | ||
