A projector system includes a first projection section projecting inputted image information onto a projection target, a laser pointer pointing a predetermined part of an image projected onto a screen 1, an image pick-up section picking up the image in a state pointed by the laser pointer, and a pointed position detecting section detecting the position of the part pointed by the laser pointer on the basis of the image information picked up by the image pick-up section. And a projection lens projects an image on the basis of the position of the part pointed by the laser pointer and detected by the pointed position detecting section and/or in correspondence to the image of the pointed part.
