Abstract

A projector divides and projects a single image onto two different projection surfaces and performs virtual user interface through one projection surface. The projector projects a VUI screen image on a desk and projects a main projected screen image on a wall. The projector includes a light receiving element, which is installed at a position that receives light emitted to the desk (the projection surface of the VUI screen image) and reflected (or scattered) by an object in the vicinity of the desk. The projector calculates a position of the object based on a light detection timing of the light-receiving element and a scanning position of light at each time and changes a projected image based on the calculated position. The projector displays a designated region of the VUI screen image to be brightened.
