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.
