Abstract
Official abstract text for this publication.
An interactive projector includes a projection section adapted to project a projected screen on a screen surface, an imaging section adapted to take an image of an area of the projected screen, and a pointing element detection section adapted to perform a detection process for detecting the pointing element based on the taken image, which is taken by the imaging section, and includes the pointing element, and the pointing element detection section sections the taken image into a plurality of small areas, and performs the detection process in at least one of the small areas using a parameter different from parameters in the rest of the small areas.
