  • Patent number: 10627962
    Abstract: A projector includes an image forming unit, a projection unit, an image capturing unit, and a detection unit. The image forming unit generates projection image data based on a video signal. The projection unit projects a projection image based on the projection image data, on a projection surface. The image capturing unit generates captured image data by capturing an image of the projection surface for each line or for each block. The detection unit detects an object other than the projection image, which included in the captured image data, based on the captured image data and the projection image data. The projection unit switches projection image for each line or for each block, by scanning. The image capturing unit starts sequential image capturing from a region of the projection surface, in which switching is completed, during a period when at least switching of the projection image is performed.
