摘要： A projector for masking out one or more objects between the projector and a screen. The projector includes an image capture sensor configured to produce a captured screen image. The projector further includes a processing device configured to receive a video-in signal, create a masking image that corresponds to at least a portion of the captured screen image, and produce a video-out signal, wherein the video-out signal comprises a combination of the video-in signal and the masking image. A panel controller in the projector receives the video-out signal and causes at least one or more pixels of at least one panel to be closed based upon the masking image such that any objects positioned between the projector and the screen are masked from any light projected by the projector.
