Abstract
Cameras that are four imagers that form an imaging system are so configured as to be capable of acquiring parallax information based on two sets of parallax images that differ from each other in terms of imaging range for acquisition of the parallax information with the inter-camera distance reduced. The acquired parallax information is used to detect a pointing element on an irradiated region that is a projection screen to achieve interactive image projection.
