Abstract:
When projecting a video in conformity to the shape of a three-dimensional object using a projector, a pattern such as a grid is projected and the projected pattern is photographed, and then the position or shape of a projection object is calculated, whereby making it possible to apply appropriate geometric transformation to a projected video. However, when a grid is projected in superposition while video content is being displayed, the grid is visible to a viewer, and that the position or shape of a projection video cannot be calculated while a video content is being displayed. The present invention uses the freedom of color representation and the color redundancy of a color wheel, buries an invisible pattern not visible to human eyes in a video, and photographs the video in synchronism with the rotation of the color wheel, thereby making it possible to discriminate the buried invisible pattern.

Claim (Index 1):
A projector that divides an input video into videos of a plurality of color components, projects the videos of the respective color components to the same position of a projection object in a time division manner, optically synthesizes the videos of the plurality of color components, and performs color display of the input video on a surface of the projection object, comprising:\n a light source; a color wheel that transmits only lights of wavelengths corresponding to the respective color components of light from the light source in the time division manner; an optical modulation device that modulates the light of the light source passing through the color wheel on the basis of a supplied color component video; a lens that projects the light modulated by the optical modulation device onto the projection object; and a projection video generation circuit that divides the input video into the videos of the plurality of color components and supplying the videos of the plurality of color components to the optical modulation device at a timing synchronized with an operation of the color wheel, wherein the color component includes at least one of three components of R, G, and B which are three primary colors and a color component other than R, G, and B, and the projection video generation circuit causes a first superimposition video pattern to be superimposed on a video of the color component other than R, G, and B and causes a second superimposition video pattern to be superimposed on each of videos of the color components of R, G, and B, the second superimposition video pattern being generated to cancel the first superimposition video pattern on a surface of the projection object when averaged in a time direction.
